Can't modify uefi boot label
I'm trying to modify a boot label that I earlier created with efibootmgr. The boot number is 0024, and the existing label is "Arch". I want to change the label to "NewArch".
Here's the command I used:
efibootmgr -b 0024 -L "NewArch"
This doesn't work, and I can't figure out why. There's no error message generated, but I see that the boot label remains as it was.
Any help would be greatly appreciated. Thanks.
The module loads fine, but that directory does not get created. If I'm reading the wiki correctly that means that UEFI isn't being used, however that doesn't make any sense since the BIOS is setup to use UEFI
Edit: Found this link; http://www.linuxquestions.org/questions … 175411129/. Seems that the guys at H2O BIOS has decided to hardcode the paths to UEFI system files. Renaming the windows file solved the problem, although it is hack alert on the highest level!

[SOLVED] Can't setup UEFI boot
Hi, I'm in the process of installing a newly bought laptop (Sony Vaio SVS1311P9EB). I'm able to boot from the install media and to install the system but when it comes to setting up the boot I run into some issues.
The HDD is formated with GPT with a EFI partition on /dev/sda3 (there is actually on on sda1 as well, but I think that one is for system recovery. It does lack the boot flag) and the arch system root on /dev/sda6, the partitions in between is used by Windows 7 (pre installed from factory). Works perfectly by the way...
The BIOS is set to use UEFI, "Boot mode" = UEFI. However even though i run 'modprobe efivars' the kernel can't detect any EFI variables, in fact the directory /sys/firmware/efi doesn't even exist.
This causes problems when I run (from the newbie install guide);
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --recheck
and
efibootmgr -c -g -d /dev/sda -p 3 -w -L "Arch Linux (GRUB)" -l '\EFI\arch_grub\grubx64.efi
The error both times are;
Fatal: Couldn't open either sysfs or procfs directories for accessing EFI variables
If I reboot the computer the BIOS ignores arch (not surprising I guess) and just jumps straight to Windows.
Any ideas how I can get around this problem?

Hi there,
just wanted to share my experience with a manual P2V Migration. The VM became to ressource hungry and it was decided to move it off an ESX 5 Cluster to a dedicated physical Machine.
V2P Virtual Machine to physical Server IBM x3650 M4 and switch from BIOS to UEFI Boot environment
Task:
V2P Migrate a VMware virtual machine to a IBM x3650 M4 with a ServeRAID 5110e RAID Controller or any other LSI RAID Controller without 3rd Party tools.
This should also work with other RAID Controllers or Servers but be sure to pick the right drivers then.
Extra Task:
The VM's boot environment/virtual BIOS is BIOS, not UEFI (as per default VMware Setting). The physical Server is running in UEFI mode.
The Challenge:
After restore the Server won't boot or get into a BSOD (7B), because the RAID drivers are missing.
After restore the VM won't boot because the boot environment has changed from BIOS to UEFI
Preparations:
An existing physical Server of the same type and with the same RAID controller and same OS would be nice for troubleshooting and checking the registry.
An existing DHCP server will make networking things easier.
Connect the new physical server x3650 M4 to power and network
create a virtual drive that has at least the size of the existing VM plus the size of the full backup (.vhd). Should be about twice the size of the original vmdk.
Get a USB Flash stick (I used a 8GB modell so no problem with larger sticks)
Download and extract LSI MegaRAID Driver on that USB media (I used 6.705.05.00-MR_Windows_Driver directly from LSI website)
Download and extract INTEL Network Adapter Driver on that USB media (I used 12.11.97.0 of e1r62x64.inf from 19.5 driver release from 2014.09.26 directly from LSI website)
Step by Step:
if you have an other physical Server of the same type and same Controller and same OS:
1. open regedit and export everything related to SCSIAdapter and megasas2 to .reg files or skip this step and use my files below
some of this (sub)keys may not be accesible - you will then first take ownership and/or modify permissions to read them
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B-E325-11CE-BFC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1000&DEV_005B&SUBSYS_04121014&REV_05
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\megasas2
this one is more complicated:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase (only relevant are those devices where the service name is megasas2 - export the whole subkey and get the filtering done with tools like notepad++)
Make a copy of the following files/folders:
c:\programdata\LSI\
c:\windows\inf\megasas2.INF
c:\windows\inf\megasas2.PNF
c:\windows\system32\drivers\megasas2.SYS
on the existing VM:
1. create a full backup (image) with the built-in Windows Backup Utility and save it in an accessible network location (you will need this one, if anything goes wrong or you want to come back to this point.
Alternatively you could create a VMware snapshot.
2. import the .reg files you created earlier or import my files below.
Attention: This will make the VM unbootable!
But it is required to prepare the VM for the new RAID controller when it will be restored on the physical server.
Do NOT reboot now as this will make the VM unbootable!
4. Copy the LSI folder and the megasas2.INF/PNF/SYS files to the appropriate destination folders on the VM.
3. again create a full backup (image) with the built-in Windows Backup Utility and save it in an other accessible network location but not where you safed the first backup.
This will be the "golden" backup if you want, where the RAID controller is prepares. We will rebuild the new machine with this second backup.
4. Optional: you could use the Backuputility now to restore the Systemstate of the first backup and reboot or restore the VMware snapshot.
This will undo the changes we made to the VM.
on the new physical server:
1. boot the physical server from Windows Server 2008 R2 SP1 DVD
2. when it is ready to install, press shift+F10 to get command prompt and do not click to install Server 2008
3. check driveletter of the USB stick with diskpart list vol (was C: at my Server, so don't wonder about that letter)
3. load drivers for ServeRAID SAS controller (this is mandatory to see the volume in diskpart)
drvload c:\srv_2008_x64\megasas2.inf
4. load drivers for INTEL I350 Gigabit NIC's (you will need this to access the backup that is on the network)
drvload c:\PRO1000\NDIS62\e1r62x64.inf
5. wpeinit (will start network. wait ~15 sec to let it start and get IP address)
check if you have IP connectivity an address with ipconfig, if not, use an other NIC driver and repeat steps 4+5
6. create the EFI and BCD
diskpart
list disk
select disk x (where x is the number of the disk to convert)
clean
convert gpt
create partition EFI size=128
format fs=fat32 quick label=EFI
assign letter=i or any other free drive letter
create partition MSR size=128
6.1 Copy EFI bootloader to EFI partition
i: (where i is the letter of your EFI partition)
mkdir EFI\Boot
mkdir EFI\Microsoft\Boot
copy x:\Windows\Boot\EFI\bootmgfw.efi i:\EFI\Microsoft\Boot (where x ist the default letter of the current Windows PE environment)
copy x:\Windows\Boot\EFI\bootmgfw.efi i:\EFI\Boot\bootx64.efi (note that the file will be renamed to bootx64.efi)
7. create the new partitions
diskpart
create partition primary size=100000 (edit the size to your needs. this will later become the system drive of your server)
format fs=ntfs quick label=Windows
assign letter=Y or any other free drive letter
create partition primary size=990000 (this will temporarily store your backup and we need it for the restore process)
format fs=ntfs quick label=Backup
assign letter=B or any other free drive letter
exit
8. map network drive and copy the backup .vhd to the local disk
net use L: \\networklocation\where\you\saved\the\backup (enter the credentials when asked)
copy the .vhd file that contains the OS of your VM to the local Backup Partition B. The relevant vhd file is usually the largest file in that fileset.
Note that the names are very similarly - be sure to get the correct file!
copy "L:\WindowsImageBackup\VMNAME\Backup 2015-02-03 123456\00e767c6-xxxx-xxxx-xxxxxxxxxxxx.vhd" B:\
give it time, this is slow and will take some minutes/hours and you will not see any progress! Look at the disk-LED's to see if anything is still happening
9. mount the .vhd and copy it's contents to the new system partition
Note that you can only mount a locally stored .vhd. You cannot mount a .vhd in a network location.
diskpart
select vdisk file=B:\00e767c6-xxxx-xxxx-xxxxxxxxxxxx.vhd
attach vdisk
select vol 5 (where 5 is the number of the mounted vdisk)
assign letter=Z or any other free drive letter
exit
10. Restore the files from the image
z: (where z is the letter of your mounted .vhd)
xcopy * Y:\ /e /c /h /k /o /b /q /y (where Y: is the letter of your new partition with the label "Windows")
several "Access denied" messages appear, ignore them. Those are SystemVolumeInformation folders.
11. Create Boot Configuration Data (BCD)
bootrec /RebuildBcd
this will try to repair the missing BCD on the second of the two small partitions we created earlier in and should normally work, otherwise you'll have to create BCD manually (search google for that procedure)
Note that it may find more than one Windows installation and ask which sould be added to the boot list. Be sure to select only the one that is in the correct Volume (Y:\)
that's it - exit the DOS command box and close the "Install Windows" Window, after a prompt it will reboot.
Select "Start Windows Normally", if Windows Error Recovery appears.
12. Preparing Windows
When Windows boots for the first time, DO NOT reboot if you are asked, it won't come back at this stage!
Install Intel chipset drivers for the Server (I used "intc_dd_inteldp_9.4.0.1026_windows_32-64.exe" from IBM website)
Open Device Manager, uninstall the "RAID-Controller" with the exclamation mark. You cannot install the correct driver for this Device at this point, it will bring you the error: "Cannot create a stable subkey under a volatile
parent key"
Once again, DO NOT reboot!
In Device Manager select Action>Add Legacy Hardware
click Next
select Hardware manually
select Storage Controller as Type
LSI should be listed, select "LSI MegaRAID SAS 9281-8E"
click Next, ignore the error "Code 10" Message.
Click Done.
Rightclick the LSI MegaRAID SAS 9281-8E device with the exclamation mark in Device Manager
select Update driver
select Browse my computer for driver software
select let me pick from a list of device drivers on my computer
select "Have Disk"
browse to the folder where the extracted RAID driver 6.705.05.00-MR_Windows_Driver is located (e.g. USB Flash stick E:\6.705.05.00-MR_Windows_Driver\srv_2008_x64)
then unselect "Show Compatible Hardware"
on the right side, scroll up and select "IBM ServeRAID M5110e SAS/SSATA Controller"
ignore the Update Driver Warning and click Yes
click Next, ignore the error "Code 10" Message.
ignore the exclamation mark on "IBM ServeRAID M5110e SAS/SSATA Controller" in Device Manager but be sure that there is only this controller and no other RAID-Controller or LSI SAS Controller listed under "Other Devices"
or "Storage Controllers"
NOW you are safe to reboot
After reboot you will find two "IBM ServeRAID M5110e SAS/SSATA Controller" in Device Manager
Rightclick and uninstall the one with the exclamation mark. Do not tick the checkbox to remove the driver as well!
You're done!! (hopefully)Windows Registry Editor Version 5.00

[SOLVED] Using Apple's UEFI boot menu with Arch
Hello,
I've successfully installed arch on my mid-2012 (5,1) 11" Macbook Air, and now I'm trying to get an entry in apple's boot menu (the one that shows when you hold 'option' when starting the computer). From the author of rEFInd's install instructions (http://www.rodsbooks.com/refind/installing.html#osx) it sounds like I can just add some files to `/dev/sda1` (a vfat directory that contains the stuff needed to boot macos), and then run apple's `bless` command and we're good to go. Unfortunately I've tried this a bunch of different ways, to no avail. I think some of my failure is simply because of a misunderstanding of UEFI, here are some questions I (partially) don't understand and my current understanding of them:
1. Do I even need a bootloader on a pure GPT/UEFI system? It seems like the answer is no, and I can just use the UEFI firmware and the linux kernel to load Arch (per: https://wiki.archlinux.org/index.php/UE … ux_Kernel). Note: I'd like to have as little software between the firmware and the os, for speed and simplicity. However, I'd still like to dual boot, but it sounds like the firmware can handle showing me a menu as long as there are entries pointing to parts of each OS.
2. Will grub/rEFInd/syslinux do some of the work for me initially/on a kernel update? I think the answer is yes, which would be motivation (esp when I need to update the kernel) to just use a multibootloader and have it handle arch and the firmware pass control to either that or MacOS
3. Will `efibootmgr` brick my mac? https://wiki.archlinux.org/index.php/UE … FI_systems says it will, but I think the `grub-install` command uses `efibootmgr`, so should I not try grub on here (this package: https://www.archlinux.org/packages/core … fi-x86_64/ ). Also some of the other packages (like rEFInd-efi) depend on efibootmgr, so does that mean any kind of an install from them (a command from the package, not the `pacman -S pkg` command) will also brick my system? (see rEFInd-efi dependencies: https://www.archlinux.org/packages/extr … efind-efi/ )
I've been searching a bunch of different things, output of the `bless` commands I've been running, and have found the following:
* https://bbs.archlinux.org/viewtopic.php?id=148647
* Using OSX to install rEFInd manually (moving the files around and using OSXs `bless` command) http://www.rodsbooks.com/refind/installing.html#osx , I used the rEFInd files from Archs repos: https://www.archlinux.org/packages/extr … efind-efi/ )
* The Wiki docs on rEFInd https://wiki.archlinux.org/index.php/UE … ing_rEFInd
To summarize, I'm trying to set up a dual boot between MacOS (installed) and Arch (also installed, there's just no way to boot it on my system yet) using Apple's built in menu that deals with the EFI partition on /dev/sda1 . Thanks in advance for any help!

Not quite. That makes a boot loader bootable, but it doesn't add an entry to Apple's boot manager menu. There's a blog post somewhere by Matthew Garrett that describes the steps necessary to add something to Apple's boot manager, but I couldn't find it in a quick Web search. Maybe you'll have better luck, or be able to track down the same information somewhere else. As I recall, it involves using a separate HFS+ volume, creating two or three dummy files, and using "bless" in OS X.
1. Do I even need a bootloader on a pure GPT/UEFI system?
Yes, you do need a boot loader. It's important to distinguish between a boot loader and a boot manager, though. The former is a program that loads a kernel, and perhaps associated data, into memory and transfers control to the kernel. A boot manager presents a user interface that enables you to select which OS (or which boot loader) to launch. A boot manager is not strictly necessary, and Apple's EFI implementation includes its own simple boot manager, which is what you've been unsuccessful in configuring.
Note: I'd like to have as little software between the firmware and the os, for speed and simplicity. However, I'd still like to dual boot, but it sounds like the firmware can handle showing me a menu as long as there are entries pointing to parts of each OS.
Many people make do with the firmware's own boot manager, but this can be rather inflexible. I'm not even sure if Apple's boot manager can handle passing options to Linux kernels' EFI stub loaders. This ability is not absolutely required, but without it you must compile your options into your kernel at compile time, which greatly reduces flexibility since you can't modify the options on a per-boot basis -- say, to boot into single-user mode if this is required.
2. Will grub/rEFInd/syslinux do some of the work for me initially/on a kernel update?
The usual Arch Linux method of handling kernel updates is to overwrite an old kernel with a new one, so no boot loader/boot manager changes are required. If you want to keep numbered kernels around (as most other distributions do), GRUB provides scripts that can help automate changes, but they are required in the grub.cfg file. rEFInd can auto-detect boot loaders, and if you're using the EFI stub loader, that means that the kernel is its own boot loader, and with a proper configuration, rEFInd can detect new kernels without changing its configuration file.
SYSLINUX has some very early and very experimental EFI support. The one and only time I tried it (about a month ago), it wouldn't compile for me. (I don't know of a precompiled binary available on the Web -- the support is that new!) I don't recommend trying it unless somebody who's gotten it to work offers to help you personally.
3. Will `efibootmgr` brick my mac? https://wiki.archlinux.org/index.php/UE … FI_systems says it will, but I think the `grub-install` command uses `efibootmgr`, so should I not try grub on here (this package: https://www.archlinux.org/packages/core … fi-x86_64/ ).
There were reports of efibootmgr damaging Mac firmware several months ago (I believe over a year ago). Since then I've seen claims that this problem has been fixed with recent kernels (3.0 and later, IIRC), but I've seen no substantiation one way or the other. Overall, I recommend caution....
Also some of the other packages (like rEFInd-efi) depend on efibootmgr, so does that mean any kind of an install from them (a command from the package, not the `pacman -S pkg` command) will also brick my system? (see rEFInd-efi dependencies: https://www.archlinux.org/packages/extr … efind-efi/ )
On a Mac, I recommend installing rEFInd (or any other EFI boot loader) from OS X rather than from Linux. (Note that I'm rEFInd's maintainer, so that's an official recommendation from the software's developer.) Offhand, I don't know if the Arch package for rEFInd runs efibootmgr automatically on boot or just has it as a dependency because efibootmgr is the usual way to register a boot loader on UEFI systems. If the latter, it should be safe to install the Arch package for rEFInd, copy its files, and then reboot to OS X to run bless on it. It would be just as easy, if not easier, to install it completely from OS X, though. -
How can I hide a text label as I would a control or indicator?
As I have multiple indicators that must have the same identifier to the operator I can not use the indicator label as the items identifier. At times I want to hide the indicator and label. How can I hide the label? Please recall a text label just sits on the front panel as desired. It isn't within a raised or lowered box. In the attached sample I would like to hide "MyLabel" when the date indicator is hidden.
Attachments:
Test_Label.vi 35 KBHere�s a way. Its a little involved, but it will work:
1. Customize a control or indicator to remove the border (I used a string control)
a. Right click on the control or indicator, go to �Advanced � Customize�
b. Click on the wrench on the tool bar to enter edit mode
c. Select the border and drag it off to the side
d. Reduce the size of the border to a single pixel (it won�t let you delete it)
e. Rubber band a box around the 1 pixel border to select it and use the cursor keys to move it within the �white space� of the string control. It will effectively disappear. You will NOT be able to move it with the mouse as LV will try to resize the border instead of moving it.
f. Using the color tools �suck up� the background color of your vi and �paint� i
t into the white space of the control.
g. Make the control the correct size to hide your label(s). Make sure it is right as you will NOT be able to resize the control outside of the �customize� function (i.e.: while on your front panel)
h. Click on the tweezers to go back to customize mode.
i. Give your control a descriptive name
j. Right click on the control, go to �Visible Items� and uncheck �label� to hide the label.
k. Save your new control
2. Back on your front panel, place your new control over what you want to hide and programmatically make it visible or invisible as desired.
I have included a copy of your original vi, modified to hide and unhide your label. I have also included the customized string control that accomplishes this. You may resize the control as needed by �customizing it as described above.
The only disadvantage to this method is that if you want to hide multiple labels they must be in the same area of the front panel. Otherwise you must have seve
ral �hiding� controls.
An advantage is that you will not have to make the original control or indicator (i.e.: the date indicator) visible or invisible as it can be hidden as well.
Hope this does what you want.
Good Luck.

How can i modify a step type description?
I need to modify the description of some custom step types. I saw how this is made in the Basic Ivi step types. What i want to do is to display the current selected operation for an ivi step type as is done in the basic Ivi step type. Isaw that this is done just evaluating the vriable instrOperation and depending on the value you guys insert a name corresponding to that value.
I tried to do the same and modified a custom step's description in order to display the currently selected oparation. The problem is that i can't display any label...instead of the label i want to appear i get a "String not found in Table" message in the step's description. What table is this?...Do i need to make the changes i want in a table or i can just use some predefined labels?...this is because with simple words like FREQUENCY or INIT the description seems to work fine. What can i do to solve the problem?
This is the description i have in the step:
ResStr("IVI_STEP_TYPE", "IVI", "IVI") + " " + ResStr("IVI_STEP_TYPE", "Counter", "Counter") + ": " + ((Step.LogicalName=="") ? ResStr("IVI_STEP_TYPE", "UNSPECIFIED LOGICAL NAME", "UNSPECIFIED LOGICAL NAME") : LocalizeExpression(Step.LogicalName)) + ", " + ResStr("IVI_STEP_TYPE", ((Step.Operation==0) ? "CONF FREQUENCY" : ((Step.Operation==1) ? "MEASURE" : ((Step.Operation==2) ? "READ" : ((Step.Operation==3) ? "INIT" : ((Step.Operation==4) ? "STATUS" : ((Step.Operation==5) ? "ABORT" : ((Step.Operation==6) ? "FETCH" : ((Step.Operation==7) ? "PERIOD" : ((Step.Operation==8) ? "CONF. VERTICAL" : ((Step.Operation==9) ? "CONF. INPUT IMPEDANCE" : ((Step.Operation==10) ? "CONF. BANDPASS FILTER" : ((Step.Operation==11) ? "CONF. LOWPASS FILTER" : ((Step.Operation==12) ? "CONF. HIGHPASS FILTER" : ((Step.Operation==13) ? "UNCONFIGURE FILTER" : ((Step.Operation==14) ? "SECONDARY EVENT" : ((Step.Operation==15) ? "RISE TIME" : ((Step.Operation==16) ? "FALL TIME" : ((Step.Operation==17) ? "POSITIVE PULSE" : ((Step.Operation==18) ? "NEGATIVE PULSE" : ((Step.Operation==19) ? "CONF. INTERVAL X TO Y MEAS" : ((Step.Operation==20) ? "CONF. PHASE X TO Y MEAS" : ((Step.Operation==21) ? "MEASURE X TO Y" : ((Step.Operation==22) ? "CONF. EXT. START ARM" : ((Step.Operation==23) ? "CONF. IMM START ARM" : ((Step.Operation==24) ? "CONF. EXT. STOP ARM" : ((Step.Operation==25) ? "CONF.TIME STOP ARM" : ((Step.Operation==26) ? "CONF. DIGITS STOP ARM" : "INVALID OPERATION"))))))))))))))))))))))))))))
and this is the description i get in some of the steps:
Ivi Counter, "Sample Counter", String not found in tableEromero -
The ResStr function retrieves a string from the TestStand language resource files. We call this a table. The funtion requires a category and tag value name. Review the Creating String Resource Files section in Chapter 3, page 6 of the User Manual for more details.
So the strings that you are already referencing are in the IviStepTypes.ini file in the
Components\NI\Language\English directory. You could add your new strings that you require to a sister file that you would create under the Components\User\Language\English directory, or you can remove the call to ResStr and just hardcode the string with your step type if you do not want the ability to translate the string for other languages.
The call that is probably failing is:
ResStr
("IVI_STEP_TYPE", ((Step.Operation==0) ? "CONF FREQUENCY" : ...
Also, right now the call to ResStr("IVI_STEP_TYPE", "Counter", "Counter") is probably failing and just using the default value you supply in the call.

Hi,
We have designed some BI queries, when we open Query Designer and execute them (CTRL + R) an Internet Explorer open and ask us to log on this BI Portal.
On this Portal login screen, I can only provide my user name and password.
We would like the user to be able to select the language and to change is password.
How can we enable those changes ?
Thanks,
HugoAlthough in iSQL*Plus 9.0.1 you can't modify the default
login HTML, you can create your own static HTML "login"
page. Just make sure the correct login credential
parameters are passed to the iSQL*Plus URL. Your users will
have to call your new static page instead of the default
iSQL*Plus login page.
Copy the HTML from the default login page and change the
FORM ACTION to include the host and port:
<FORM ACTION="http://host.port/isqlplus" METHOD="post">
and change the "Connection Identifier" field to a drop down
list of the connection identifiers you want:
<TD CLASS="label">Connection Identifier:</TD>
<TD>
<SELECT NAME="sid">
<OPTION SELECTED>SID1</OPTION>
<OPTION>SID2</OPTION>
<OPTION>SID3</OPTION>
</SELECT>
</TD>
Add your own logo, joke of the day, and put it in
production....
iSQL*Plus 9iR2 has an option for a drop down list of connect
identifiers to be configured in the default login screen.
This allows sys admins to restrict the DB servers that can
be accessed. No other connect identifiers can be used, even
from CONNECT commands in scripts.
On the OTN home page there seems to be an "early access"
link for down loading the 9i Database R2.

Booting hangs at loading vmlinuz-arch.efi (UEFI boot)
Hello,
I have just installed Arch Linux on my desktop machine (UEFI motherboard) which contains drives & partitions as follows:
1. /dev/sda (~ 250 GB) with
1: Win 7 64 bit
2: ntfs partition for data
3: ntfs partition for programs
2. /dev/sdb (1 TB) with
1: ntfs
2: fat32 / vfat as the uefi partition thingy
3: linux fs with swap, root and home
I have followed the Beginners' Guide dow nto the letter.
So I used rEFInd to set up the UEFI boot manager. However, it hangs at using the vmlinuz-arch.efi file/partition (?) on boot.
I have tried booting with a new efibootmgr entry as well, but it still hangs.
At this point, I'd like to know:
How can I get rid of all the rEFInd boot manager entries?
What precisely do I have to do to get it working? I could, of course, read around on here all day, but I somehow won't really learn anything as I can't deduct the right path of action for myself. If the machine weren't my productive system I'd definitely "play" around a lot more, that's for sure.
Any advice is greatly appreciated.henrik wrote:

OK, i will post, maybe it can help you!
First you need to boot from the arch installation media in UEFI mode. Mount your system partitions and chroot into it.
If you only have refind and kernel files under /boot/efi/ you can delete all files (clearing the EFI partition).Then run
modprobe efivars
. If you want to remove any efi entry, you can do it with
efibootmgr -b <entry_number> -B
Ok I did that.
sed -i "s/root=PARTUUID=XXXXXXXX rootfstype=XXXX ro/root=UUID=$(blkid -s UUID -o value $(df -k /)) rootfstype=$(blkid -s TYPE -o value $(df -k /)) ro/" "/boot/refind_linux.conf"
You meant here for me as wlel to exchange the X's wit hthe corresponding keys, right? I mean I did it. Would not make sense to me to call the comman with lots of Xs.
The rest was quite easy, I paid a lot of attention and made sure I typed in everthing correctly.
I am now at a blank black screen and there is a white underscore flashing in the upper left corner.
edit Can't boot into Windows anymore. Can't repair the MBR / UEFI boot with the Windows 7 DVD either...
edit2 Did lots of googling and at least Win 7 works fine again.
No. All the code is for you to type exactly as it is. The only statements you need to replace are <drive_with_efi_partition> and <efi_partition_number> with your current setup. What the line you questioned does is to replace the lines with "root=PARTUUID=XXXXXXXX rootfstype=XXXX ro" using the linux "sed" command, in refind_linux.conf with "root=UUID=<autodetected_uuid_of_your_root_partiton> rootfstype=ext4 ro". That will only work with the original refind_linux.conf, so if you edited it, you need to rerun
cp -r /usr/lib/refind/config/refind_linux.conf /boot/
There are 3 main reasons that may caused you to boot into a black screen with nothing written on it.
1. By not writing the code as it is, and editing files by hand instead, you may have done something wrong;
2. Your computer is booting from the wrong uefi entry, intead of the one created earlier;
3. You need to have "nomodeset" in your kernel boot line.
When does the black screen apears? After selecting a refind entry from refind's menu? Right after the pc boots (refind menu does not appear)
Another thing. In order for you to have access to windows, you need to edit refind.conf windows corresponding entry and remove the disabled statement or it wont appear on refind menu

Disabling UEFI boot or prioritizing legacy boot in dv6tqe-7000 laptop
Hey guys, I currently have windows 7 on my pavilion laptop. I'm trying to install ubuntu 14.04.1 LTS on it from the cd-rom drive. Unfortunately, the ubuntu installer does not detect my hard drive's windows 7 partition while booting in UEFI mode as Windows 7 was installed in legacy/bios mode.
I want to either disable UEFI booting or to make the bios prioritize BIOS/legacy boot ahead of UEFI so I can correctly install a second OS. Unfortunately, the bios options I see do not seem to allow me to switch to a legacy boot, they only allow me to change the boot priority within each of those modes. Is there any way for me to boot with legacy?
A screenshot of what I see in the boot options menu in the bios is here: http://imgur.com/aBaZ0Xi
The blue items are the only things that are selectable; the gray/black items cannot be navigated to.Anyone?

Extended partition on old MBR HDD makes Windows 7 UEFI boot fail
There seems to be a bug in Windows 7 Pro x64 that prevents it from booting on a GPT partitioned HDD when the same machine also has an MBR partitioned HDD with an extended partition.
I have a UEFI bootable PC with two HDDs:
Disk 0 is GPT partitioned and contains Windows 7 Pro x64 and openSUSE systems.
Disk 1 is MBR partitioned and contains Windows XP Pro x64 systems and bootable ISO images.
Both the disks also have separate partitions for data and for booting.
They are normally booted via rEFInd on disk 0 as follows:
UEFI => rEFInd => Windows 7 or GRUB2.
UEFI => rEFInd => disk 1 MBR => GRUB4DOS.
I had previously installed Windows 7 when it was first released, but abandoned it in favour of XP and openSUSE instead. With the end of support for XP I decided to re-install W7. Before doing so I unplugged disk 1 to ensure that W7 booted completely
independently of XP. After installing W7 I installed SP1 and all the Windows updates. The new W7 system could be booted without problem via rEFInd => \EFI\Microsoft\Boot\bootmgfw.efi
However when I plugged in disk 1 W7 would no longer boot. It displayed the message "Windows is Loading Files" as the bar progressed twice before returning to the rEFInd menu. On selecting W7 again it presented the option to "Launch
Startup Repair", but on doing so it too just displayed "loading files" and returned to the reEFInd menu.
I UEFI booted from the installation DVD and ran Repair. When re-booted W7 presented a menu with choice of new and recovered systems, but both failed as before. Neither could be booted in safe mode. Booting directly from the UEFI firmware menu
into W7, instead of via rEFInd, gave similar results.
Investigations showed that the problem is caused by the extended partition on disk 1. If it is deleted, or just hidden by changing the partition type from 0x0F to 0x00, then W7 boots OK. Plugging in an external USB HDD with logical partitions also
prevents W7 from booting.
This all seemed to be similar to the problem described in KB979374, so I downloaded the hotfix (404153_intl_x64_zip.exe), which is supposed to be applicable to Windows 7 as well as WindowsServer 2008 R2. However when the hotfix was run it displayed "The
update is not applicable to your computer" and logged the following error:
error 2149842967 "" (Command line: ""C:\Windows\system32\wusa.exe" "<pathname>\Windows6.1-KB979374-x64.msu" ")
Is this because the version of files mentioned in KB979374 is older (6.1.7600.20617) than the version of Winload.exe in my system (6.1.7601.17556)?
According to http://www.techienewsnetwork.com/247/22/ SP1 included hotfix 979374, but it doesn't appear in the list of Installed Updates given in my W7 control panel. Should it, are hotfixes included in a service pack listed individually? If
not is there any way to tell whether or not hotfix 979374 has been applied?
How can W7 be booted without having to change the partition type code of extended partitions every time, is there a newer hotfix that will fix the problem in Windows 7 SP1?
Almost all the references I can find to this problem are at least 2 years old, which suggests it might have been fixed. Does anyone else with an up to date Windows 7 SP1 have this problem with extended partitions. An easy test is to plug in an external
HDD with logical partitions and see if W7 will still boot.
I don't want to convert disk 1 to GPT as that would make XP un-bootable. Also GRUB4DOS only supports MBR, and it is very useful for booting ISO images as well as XP.
Cheers.Hi Wade,
To be sure that openSUSE, XP, or any other software on my PC isn't part of the problem I decided to do a new install of Windows 7 on a blank HDD. As I don't have a spare one I had to backup everything on disk 1 (MBR) and then wipe it, including the MBR,
with zeros (using AOMEI Partition Assistant).
I unplugged the original disk 0 so that the PC had just single completely blank HDD (previously disk 1), UEFI booted the Windows 7 DVD and installed W7 again. Unfortunately at this first attempt W7 partitioned the blank HDD as an MBR disk and booted
in legacy BIOS mode, even though I had booted the DVD in UEFI mode. So I deleted all the partitions it had just created and converted the disk to a GPT one.
The next time I installed W7 it was a UEFI one, with an EFI system partition. After installing SP1 and re-booting it a few times to make sure it was working OK I plugged in the external HDD with an extended partition before re-booting. The result
was exactly the same as reported above for the main GPT disk: it briefly flashed "Starting Windows" then displayed "Loading files" for a few seconds as the bars progressed; when Startup Repair was launched it failed as well.
After removing the HDD I booted the new W7 and added some missing drivers and installed all the Windows Updates, including the optional ones. Many hours later the result was a new up to date installation of Windows that worked perfectly (no errors in
any log files), with no other software on the PC. However as soon as the external HDD was plugged in it failed to boot, as described previously.
I then ran Bootrec from the DVD, trying all the commands, but the results were exactly the same: everything worked successfully but no Windows installations were found, and it didn't fix the problem.
The documentation on how to use Bootrec describes how to backup the BCD store that is on the C: drive (e.g. "ren c:\boot\bcd bcd.old"). However the BCD store for UEFI based systems is in the EFI system partition, NOT on the C: drive. This suggest
that Bootrec does not apply to UEFI based systems.
Are you sure that the MBR is used when booting in UEFI mode? From what I have read in several places (not MS pages) the protective MBR on the GPT isn't used, but instead the UEFI firmware runs \EFI\Microsoft\Boot\bootmgfw.efi which looks in the BCD store
in the EFI partition. Can you point me to any MS documentation please that explains exactly how UEFI booting works for Window 7, including its use of the MBR.
Do you have a Windows 7 system that can boot from UEFI when an MBR disk with an extended partition is attached. If so how is your installation different from the one I have just set up, i.e. Windows 7 installed on a PC with just
a single empty GPT HDD?
Do you work at Microsoft? If so perhaps you could find out if anybody with a straightforward UEFI booted Windows 7 has problems when an MBR HDD with an extended partition is attached.
Sorry for the delay in responding, but a lot of work was involved. -
[SOLVED, sort of] Yet another UEFI boot issue
Hello everyone,
Let me start by saying sorry for the long (first) post.
I've ended up with a UEFI boot problem I can't solve. I've searched the forum and internet and I realize I'm not the only one who ran into problems with UEFI. Unfortunately, the problems other have had seem not similar to mine. I've spent almost 2 days now trying to figure this out, and I'm getting nowhere (though I've learnt some more about UEFI, which I guess is good). I was hoping someone here can give me some hints on how to proceed.
So lets start with the background. I recently bought a new computer (Lenovo Thinkpad Edge E530 with Windows 8) and of course I want to run ArchLinux on it (been using ArchLinux for almost 7 years now and no plans on switching). Installation went ok with only a few problems during installation that I managed to solve (or so I thought). I must admit I didn't follow the guide fully. I didn't want to remove the Restore and Windows partitions, so I figured it would be safe to reuse the existing UEFI System Partition, as long as there was enough room, which there was. Anyway, I now have a computer I can boot into ArchLinux and also Windows 8, just the way I want it, almost. There is this one final issue I haven't been able to figure out how to solve.
The problem
Whenever I reset/power on the computer, I must press Enter during the initial screen (showing a Lenovo logo, and a message about pressing Enter to interrupt normal startup). If I don't press Enter before the timeout (a second or so), the screen will go white and that's it. No beep, no message, no nothing but a white screen. A power cycle is the only way to leave this state. Occasionally the screen will be a white bar at the top and random colours below, but I'm guessing this only represents what is in graphics memory at the time (0x00, 0xFF or any other random value).
If i do press Enter however, then I'm presented with a menu where I can select what to boot; rEFInd (which is preselected) along with Windows 8 and some restore and diagnostic entries. Pressing enter will take me to the preselected rEFInd, pressing enter again (or wait for timeout) will boot linux, and I'm in. Nothing weird there. And if I select Windows in rEFInd, then windows boot, just as expected.
There is no difference whether I'm switching from Windows to Linux or Linux to Windows or just reboot the same OS I was using again. The result is the same whatever I choose to boot.
So the question is: Why do I have to select rEFInd manually and go through all these menus? Should I not be able to just power it on and let it boot the preselected rEFInd entry and continue from there, without me helping it?
Trying to solve it
Searching here and on the internet gave me some ideas on what to try, so here is a list of my attempts:
efibootmgr show me there is a rEFInd entry, and that it is the first one in boot order
I copied refindx64.efi to /boot/efi/EFI/Boot/bootx64.efi (replacing an existing entry)
I've updated the EFI firmware (from Lenovo) to the latest and greatest
One other guy had almost the same issue, but with a single boot of Windows. He solved it with Microsoft Boot Manager (there is an Automatic Repair, or something). I even dared trying this, though I must admit I was a bit hesitant about letting some Microsoft program trying to repair my computer. Anyway, it said it couldn't repair my problem, nor did it say I had one, so I am none the wiser.
None of the above gave anything.
So, that's it. I guess I can live with having to press Enter on every power up/reset, but it is very annoying having to do so, and even more so when I forget it because then I'm forced to power cycle it. I hope someone reading this can figure out what's going on, because I am clueless.
Best regards,
Johan

I would imagine that something coming directly from the upstream developer would be something that they should take into consideration. Also, I imagine that renaming it to refindx64.efi kind of goes against the whole "vanilla packages" thing we tout around here... so it really makes me wonder why it is done in the first place.
I've just done that:
https://bugs.archlinux.org/task/33326
It's not been very important until recently; but I've been putting a lot of effort into the ancillary support scripts (install.sh and mvrefind.sh). They necessarily rely on the files having certain names, so installing them under other names robs users of functionality.

Good luck with that!
FWIW, it seems that the number of EFI-related bug reports on Linux forums has gone way up recently. No doubt this is because EFI is now pretty much universal on new computers, so problems that used to affect one or two people now affect dozens or hundreds, and some of those post about them. -
[SOLVED] UEFI boot configuration using efibootmgr
Hello All,
I've been having a very frustrating time with efibootmgr on my HP Laptop.
I've been searching around for some information regarding the OS Bootmanager in UEFI boot and cannot find anything that works for me.
I'm trying to get efibootmgr to load the boot entries in the order that I specify, but, although it lists exactly what I want in the terminal, when it comes to a reboot, the OS Bootmanager is failing and writing new entries every boot and I cannot fathom why.
Please could someone point me in the direction of a good guide to UEFI boot/OS Bootmanager and it's configuration using efibootmgr? I have read info found in the Archwiki, but was hoping for something focussing on efibootmgr alone as a configuration tool.
Many thanks for your help,
Frazer
Last edited by frazer (2014-03-10 22:21:14)It's likely that the firmware (or maybe Windows, if you're booting into Windows between boots and haven't mentioned that fact) is changing the boot order. Unfortunately, some EFIs do that, or worse.
I recommend you start by upgrading your firmware. (In some cases, this will wipe out all your boot entries, so be prepared.) If the problem continues, either file a bug report with the manufacturer or return the hardware for a refund and buy something else. The manufacturers have had a long enough time to work out such major problems with their firmware, and returning defective hardware is really the only thing we as consumers can do that will get the manufacturers' attention.
If you must keep the hardware and a firmware update doesn't help, you may just need to find a workaround. If you need advice on doing that, you'll need to provide more details about what your setup is -- in particular, what you want the boot manager's boot list to look like (as in "efibootmgr -v" output once it's configured) and how the firmware is reshaping that when you reboot. -
[SOLVED] UEFI-boot on Intel-NUC
Anyone got UEFI-boot working on Intel NUC?
In BIOS i have enabled UEFI and disabled secure boot.
With the latest bootable arch media it boots okay in UEFI-mode.
ls -l /sys/firmware/efi shows a list of files.
If i boot into UEFI shell v 2.0 (from the USB) i can start arch with
fs1:\EFI\arch_grub\grubx64.efi
I have followed the installation guide and created a EFI (fat32) partition on GPT.
I tried to add the entry with both efibootmgr and bcfg, but it doesn't seem like it's being read. I find the entries with bcfg boot dump, but not in intels BIOS under (boot drive order)
It only gives me "a bootable device has not been detected" on startup
