Change boot device

I have SunFire V210 with no internal CD/DVD drive. How do I get it to boot from an external
cd drive.
I do a probe-scsi-all and I get the following:
/pci@1d,700000/pci@1/scsi@5
Target 0
Unit 0 Disk SEAGATE ST373307LSUN72G 0207
Target 1
Unit 0 Disk HITACHI DK32EJ72NSUN72G PQ08
Target 6
Unit 0 Removable Read Only device PLEXTOR CD-ROM PX-40TS 1.11
I tried
boot /pci@1d,700000/pci@1/scsi@5/cdrom@6,0:f
and I get:
Boot device: /pci@1d,700000/pci@1/scsi@5/cdrom@6,0:f File and args:
Evaluating:
Can't locate boot device
thanks,

Try:
boot /pci@1d,700000/pci@1/scsi@5/sd@6,0:f
Since probe-scsi-all sees it then we should probably be using "sd" as in "scsi disk". cdrom@ would be used if it were other than SCSI, such as IDE.

Solaris 10 installation says I changed boot device when I didn't

Hello,
I'm new at Solaris 10, and have been trying to do a net install with Solaris 10 8/07 (127111-11, s10s_u4wos_12b) on
a brand new (but older version of Solaris 10, which is now wiped out) V245 Sunfire.
When it comes to setting up the disk for installation, I have tried a couple of different things, but all seem
to result in
"Warning: Different Boot Device
Because you have changed the boot device (where the root ('/')
file system will be created) from its previous location, you
must re-layout your disks to sync up file systems. "
So -- I have tried manual layout, auto layout (following is what I want) -- and the first
screen tells me that c0t0d0 IS my boot device!

Immediately after the "remote server" and next screen, it says:

Then it suggests going back and changing the default for EEPROM -- but -- does not allow me to go back!
At this point it appears to be installing. But it just sits at the timeline screen

Forever.
Where am I going wrong?
Thanks for any clues!!!
- Judy

Well, actually I don't have a console directly plugged in -- so I only have the secure console server
access, which seems to lock me into the single window mode where the installation stalls.
I left it going all weekend and it still stalls immediately when the installation is
supposed to begin (the "solaris initial install" screen with the percent completed bar at the bottom).
So I am unable to access the system (ctrl-c, ctrl-z do not seem to have any effect) other than
the installation guide interface. How do I get past this problem? Is it something to do with
when I turned off the firmware that keeps popping up the DHCP message (I'm not going to have
this machine's IP dynamically assigned)??? Is there something in the firmware that I need
to set???
Thanks again for help!

Change Boot Device to Use CD First - Win7 - HP1360t

In trying to solve another problem with my PC I loaded my Ghost CD so that on reboot I could use Ghost to revert the system. But the system never went to the CD drive and instead booted normally. As it turned out the boot worked and somehow my origianl problem was solved. But I still need to make sure the CD device is tried first.
I've gone into the BIOS and I notice that the CD drive is 1st in the list under the Legacy list and I can move the arrow up and down, and hit enter all I want, but nothing indicates that the CD is the first drive to try on boot.
What am I doing wrong, or not understanding?

When requesting assistance, please provide the complete model name and/or product number of the HP computer in question. HP/Compaq makes thousands of models of computers that are all different. Without this information it may be difficult or impossible to assist you in resolving your issue.
"HP1360t" doesn't appear to be a valid model name or product number. Assuming you mean you have a HP Pavilion HPE h8-1360t CTO Desktop Computer and it is has a UEFI compatible BIOS, the Legacy boot options will always occur after the UEFI boot options. For example...
UEFI - Hard Drive
UEFI - Internal CD/DVD
Legacy - Internal CD/DVD
Legacy - Hard Drive
As long as the UEFI Hard Drive is connected and functional, it will boot ahead of any Legacy device. If you move the UEFI CD/DVD above the UEFI Hard Drive and the Ghost CD is UEFI boot compliant, it may be possible to get it to boot before the Hard Drive.Additionally, you should be able to tap "ESC" or "F9" immediately after turning on your computer and directly select at boot device from the menu. This method should allow you to boot the "Ghost CD" regardless of it being UEFI or Legacy.
Please send KUDOs

How to change Boot device order to enable install of OS from CD/DVD?

Yoga 3 Pro P1370
I have an external USB CD/DVD drive. I would like to from YOGA "OFF", boot to this drive.
From YOGA "OFF" tried the tiny button (pused with pencil point), choose boot menu, this is using "windows boot mgr.", it said to use the "UP & Down" arrows to, change then press <enter>
The up & down arrows offered NO other choices than what was already there.
So from off how do i boot to the CD/DVD plugged into the USB port?
Thanks

Hi,
First go to BIOS setup and turn off secure boot. If that doesn't do it, switch the boot mode from UEFI to legacy.
What's on the CD you're trying to boot?

IPMITOOL - change the booting device from disk to network

I am using ipmitool utility to change boot device on Sun T3 machine. Currently DISK is set as boot device for Sun T3 machine. I am running the following ipmitool utility commands to force boot from network. But everytime I power on/off the Sun T3 machine, it always boots from DISK.
The setup I am in is the following:
I use ipmitool and connect to ilom of sun t3 and perform/monitor the sun t3 host machine.
Thanks.

Thanks.
The host machine is Sparc Sun T3. It is not x86 hardware.
Ideally I would like to use ipmitool to change the boot device. The commands I am running are the following:
ipmitool -I lanplus -H xxx.xxx.xxx.xxx -U root -P tom chassis bootdev pxe clear-cmos=yes
ipmitool -I lanplus -H xxx.xxx.xxx.xxx -U root -P tom chassis bootparam set bootflag force_pxe
Both commands run to successful but no effect on changing the boot device.
I tried with obp command and SP command like you mentioned below, both are not change the boot order. Not tired eeprom yet.
ideally i want to write a shell script which when run would connect to ilom of Sun T3 Sparc and run change the boot device.

S10-3: Change BIOS boot device sequence with + - keys does'nt work

I want to boot my IdeaPad S10-3 from an USB HDD.
In the default BIOS setting this is the 4th or 5th line in the boot device list.
The help instructions in the right column of the BIOS page tell me to use the <+> and <-> keys to move an entry up or down. When I do this, the BIOS only responds with annoyed beeps.
If the keys refer to a numeric keypad: there is none, and neither an indication how to map one onto the existing keys.
Is this Netbook delivered with a BIOS that was designed for other PCs ?
A workaround is to press <x> twice on a device above the desired boot device:
The 1st press excludes the device, the 2nd press moves it to the end of the list.
In this Forum I have found hints that "incorrect" changes of the boot device list may disable the internal harddisk, but I can't find precise definitions of "correct" changes that avoid this.
Do I miss something or this just an improper BIOS ?

Hi KalvinKlein,
before I received your new Info about Fn+Insert , I had once more checked Fn-F7 : no effect in the BIOS.
I have also tried all non-character keys plus the "Umlaute"-keys on the German keyboard with the following result:
The key right of the "0" shifts boot device entries down in the list.
On the German keyboard this key is labelled with " ß ? \ ".
The next key on the right and left of the "Backward-Erase"-key, labelled with " ´ ` ",
pressed together with the Shift-key, moves list entries up.
Using these keys I have then set the Boot device sequence according to your suggestion :
1: USB CDROM
2: USB HDD
3: HDD
My USB-Memory stick (with BartPE installed) had been recognized as a USB HDD.
After saving with F10 and <Return> the Netbook responded with a Beep and nothing further happened.
I had to switch it off with a long press on the Power Button.
Switched on again, <F2> pressed, BIOS checked,, o.k. <ESC>,
loads Ramdisk image of BartPE from the USB-stick,
starts BartPE with XPE.
Checking available drives in the Windows Explorer resulted in :
RAMDISK ( "B:" )                (used by BartPE for temporary storage)
USB ("C:")                        (the USB-stick with the BartPE-iso file)
"Wechseldatenträger / Removable storage device"           obviously refers to an unused USB-Port
-volid ("X:") "CD-drive"    but actually another Ramdisk containing the expanded and running BartPE package
The internal harddisk is not visible !
I wonder whether this is a problem of the BIOS or whether I require special harddisk drivers (Intel Matrix Storage manager/driver or possibly AHCP drivers) for Windows XP, because my present BartPE version is based on XP, while the Netbook came with Windows 7 Starter Edition.
Further helpful hints would very much appreciated.
Kind regards

T520 with Kingston SSD and OS Win XP Sp3 - Unmountable boot device

Hello everybody,
I have a problem with the combination of our Lenovo T520 and a Kingston SSD. The last laptop we have ordered no SSD seems to be working with the laptop. I install normally WIn Xp with SP3 the installation work very well but when I begin to install new drivers and make a restart Blue Screen with unmountable boot device. Ive tried also an Corsair SSD it results with the same effect. Do have any idea what else I can do? I've also made an bios update but that also doesn't worked very well. Do you have any other Ideas that i can try to have a better result.
Best Regards
ITRUNGIS

Same problem here, spent half the day figuring out what was causing this, now I find another victim. Here's what fixed it for me: Restart WinXP with your ext. monitor connected, login to admin acct, go to "Start" menu>Control Panels>Printers and Other Hardware>NVIDIA Control Panel. Expand the Display folder on the left side and select "Set up multiple displays", then select the "Use only one display" radio button and make sure your laptop display is entered in the "Select the display you would like to use." box. Approve the changes and now it should restart without the ext. monitor connected.

Fresh install of Server 2012 R2 causes inaccessible boot device on first Reboot

Hello Everyone,
Doing a fresh install of Windows Server 2012 R2 on a SuperMicro X9DRT-HF+ motherboard based server. The server is using iSCSI boot, setup detects the iSCSI disk and copies its files, finishes the "Getting files ready for installation" "Installing
Updates" phase, reboots, takes a while and eventually gives a Blue screen with Inaccessible Boot Device error. I have tried some changing options in the BIOS, I've had Nimble (storage array) support on the phone and they confirmed the setup is correct
but for some reason after the first reboot Windows can no longer find its install files and gives a BSOD.
Additional Information:
Server: SuperMicro X9DRT-HF+ (no internal disk)
Storage: iSCSI disk provided from Nimble CS220 Array
Windows 2008 R2 Server installation will proceed without any problems.
I checked the \Windows\Panther\Setupact.log / CBS.log file and there doesn't seem to be anything indicating a problem.
I have googled a number of times to find solutions but most articles reference a similar problem after installing a particular KB (which shouldn't be the case here). Need some help :)

Hey Tim,
Thanks for your reply, since the start of this post I have also installed MDT to try a different approach to installing the OS. Using MDT I have injected the Intel I350 driver into the installation so it should be restarting with the driver loaded.
The odd thing is that when the server reboots the Windows startup screen loads for about 4 minutes before it gives the INACCESSIBLE_BOOT_DEVICE error. This would indicate to me that it sees the disk and tries to boot from it but then something goes wrong.
Other than the \Windows\Panther location is there another place I should be looking for log files during this part of the Windows install? I have reviewed all the locations listed under the TechNet library article "hh824819" (I can't post
a link to the article but a google search brings it up) but I can't seem to find a log of when the server crashes what it is doing at that point.

Can't detect boot device after factory format to new HDD

First off, I have an HP Pavilion G6 that I purchased in December 2012. Yesterday I decided to get a new HDD to upgrade it and start fresh. It's a 1TB SSD+HDD hybrid by Seagate. It installed without a hitch, and I used my HP recovery CDs to do a factory format of the disk.
It finishes, reboots, but instead of rebooting to the HP Windows 8 setup screens, it goes to what looks like Windows 8 safe mode with a box containing the date, time, and it says something along the lines of "HP diagnostics driver installation" with an OK. Clicking that or not makes it disappear, and there's a command prompt bar at the bottom left hand corner of the screen.
The screen changes to an HP screen that begins to install drivers. It finishes, and reboots to a black screen that says "no boot device detected, please install OS."
I ran a check of the drive and it's fine. I swapped my regular drive back in, and it loaded up fine. In fact that's what I'm using right now to type this.
What could be the problem here? The boot order was never changed in the BIOs. If it were the connector failing I doubt it would load the drive that's always been in the computer. Loading up the newly formatted drive in an external enclosure shows that Windows 8 is indeed on it, but on a 93GB partition even though the drive is 1TB.
I'm at a total dead end here and no one seems to know what to do!
This question was solved.

Changing Boot Order on Dual Boot Windows 8 and Ubuntu

Hi there,
Recently got a HP Pavilion g6 2213sa which came with Windows 8 (spit!) and this disgusting UEFI BIOS replacement (double spit!).
Anyway, I need to dual boot Ubuntu on my system, so I installed Ubuntu. Normally, on a non UEFI system, a "Grub" bootloader installed by Linux would take over the startup process, and allow you to choose between either Windows 8 or Ubuntu on startup.
However, on this computer, startup is just booting straight to Windows 8 despite the fact that Ubuntu and Grub IS installed.
Now, upon startup, if I press F9, then I get to change the boot-device on a one-time basis. I can either select "OS Boot Manager", which loads Windows 8, or "Ubuntu" which loads the Grub bootloader which allows me to select Windows 8 or Ubuntu.
However, when I press F10 to enter the Bios Setup with the intention of changing the boot order permanently, the Ubuntu option isn't there. Instead it has OS Manager, USB Disk, CD Rom, USB CD Rom and Network Card.
Thanks, HP for, the crappily designed BIOS.
Anyway, can anyone PLEASE provide me a way of changing the boot order so that GRUB is loaded first and NOT this crap Windows 8 rubbish (that I would happily bin if I didn't need it for work).

There is the same problem in HP 2000 laptops (in my case specifically, HP 2000-2D22DX). I did some investigation using trial and error, and this is what I found out:
There is some sort of a "recovery feature" or so that on every boot sets the very first UEFI load option to point to one of the two locations, in this order:
\EFI\Microsoft\Boot\bootmgfw.efi
\EFI\Boot\bootx64.efi
This option is displayed as "OS boot Manager" (for the first path) and something akin to "UEFI partition" for the second path, completely ignoring the actual name given to it (when you look at the EFI variables through efibootmgr, you can see that what is displayed as "OS boot Manager" actually is set to the name "Windows Boot Manager"; why anyone would do such renaming is beyond me). If you try to change the boot order so that this slot isn't the first, the UEFI will overwrite the BootOrder variable on next boot and reset it to point to "OS boot Manager" anyway.
By default, both of the paths above contain the same Microsoft bootloader (if you check the md5sum of both, you'll see they match).
So, until HP releases an updated UEFI that allows turning this "feature" off or rearranging boot options through the F10 UEFI setup, this is what you can do to get dual boot with the least amount of hackiness:
In Windows, mount the UEFI partition (mountvol S: /S mounts it as the S: drive) and copy the file \EFI\Microsoft\Boot\bootmgfw.efi to use some other name (for example, I copied it to "\EFI\Microsoft\Boot\bootmgfw.efi~", but you can change the name to anything else).
In the Windows command prompt, update the Windows UEFI entry to point to the new name: bcdedit /set {bootmgr} path \EFI\Microsoft\Boot\bootmgfw.efi~ (adapt to your set name accordingly).
Optionally, change the name of the Windows boot loader so that you would be certain that it points to the new file location: bcdedit /set {bootmgr} description "Fixed Windows path"
Install the other OS. In my case the bootloader was installed into \EFI\opensuse\grubx64.efi.
Delete the two files, \EFI\Microsoft\Boot\bootmgfw.efi and \EFI\Boot\bootx64.efi.
Use efibootmgr to delete the "OS boot Manager" entry: sudo efibootmgr -b 0000 -B
Set the new OS bootloader to be the default bootloader by using efibootmgr with the -o option. In my case, I had an entry called "opensuse" in slot Boot0001 and the updated path Windows entry in slot Boot0002, so I had to do sudo efibootmgr -o 0001,0002
Update GRUB to point the Windows entry to your renamed file (you'll have to create a new file in /etc/grub.d and rerun grub-mkconfig).
And that's it, now the UEFI will boot GRUB by default (it won't regenerate the "OS boot Manager" entry since it won't be able to find either of the two hardcoded paths and will "fall back" to properly reading the BootOrder variable), and the F9 menu will still allow choosing to boot Windows directly.

Error Message: Reboot and Select proper Boot device.

My HP desktop computer (model p6654y) will not boot directly into Windows.
I can ALWAYS make it boot into Windows by first pressing the F10 key to enter the BIOS. If I then exit the BIOS (without even making any changes), the computer will boot into Windows.
If I don't first enter the BIOS, the computer will USUALLY take me to a black screen that says:
"Reboot and Select proper Boot device. Or Insert Boot Media in selected Boot device and press a key."
At this point it won't boot any further.
Also, the last message the BIOS displays (before the error) is:
"00 USB mass storage devices found and configured".
After that, all of the lines of text on the screen move up one level and then the screen goes black and soon after I get the Proper Boot Device error.
I do not have anything plugged into USB ports except an ordinary mouse and ordinary keyboard (both of which I changed - in case they were faulty).
My BIOS is set to boot from the Hard Drive first.
I reset my CMOS.
I do not have a CD in the CD drive.
It used to be that this would ALWAYS happen if I (1) Turned off the Computer, (2) Unplugged it for 60 seconds, (3) Plugged it back in, and (4) Turned it on. Now (after trying various things), it only SOMETIMES happens when I do this.
Any ideas?

Hello @GardenGuy1,
I have read your post on how your desktop computer is having a difficult time booting into Windows, and I would be happy to assist you in this matter!
To further diagnose this issue, I recommend testing the health of your system's hard drive by following the steps in this document on Testing for Hardware Failures (Windows 7). If the hard drive is found to be in good working order, I also suggest restoring your BIOS back to factory settings. This can be done by following this document on Recovering the BIOS.
Please re-post with the results of your troubleshooting, and I look forward to your reply!

A45-S120 - WinXP corrupted, unable to change boot order to restore from DVD recovery medium

I have a Toshiba A45-S120 laptop that has previously worked fine. I hadn't turned it on for several weeks. When I tried last week, after the WinXP splash screen came up, the progress bar completed one pass and then the video froze and showed a ghosted image of the WinXP logo off to the right of the real one and the two images were displayed in alternating vertical stripes, almost as thought you were looking through vertical blinds. At that point, there was no further boot progress.
Pressing Esc got me into the BIOS page, so it doesn't appear that there was a hardware video problem. The only options that I can could in the BIOS were the time and password (which is not set). With the recovery DVD in the drive, I couldn't get the system to boot to the CD/DVD drive no matter what I did. I tried all the suggestions of F12, F2, etc., and nothing highlighted any of the row of icons across the bottom of the Toshiba spalsh screen. When I booted, unless I pressed Esc, the system recognized the failed Windows boot and went into the text screen giving me all the safe mode start options.
After typing the above, I had one other thought - to try to force the issue, I replaced the hard drive with one that should have been blank but I got the same louvered WinXP logo. Thinking maybe I had a drive that wasn't blank as it should be, I tried a known blank drive. Now I get no response from the system at all when I try to power it on, even when swapping back to either of the other hard drives.
Is this stuff symptomatic of a dying system or is there something I can do to resurrect it and force the DVD restore somehow? Refurbishing desktops is a hobby of mine but I haven't had much experience with troubleshooting and repairing laptop issues, so thanks in advance for any pointers.
JEFF
Solved!
Go to Solution.

Well, I have good news and confusing news to report...
The dongle worked as advertised. I booted with it installed, powered down and removed it, then restarted the machine. I was able to change the boot device and enter BIOS with the ability to change the boot order, etc.
I then ran the recovery process. The ghosted image restored and then, when the machine restarted, I got the same problem that started it all... the WinXP splash screen came up, the progress bar completed one pass and then the video froze and showed a ghosted image of the WinXP logo off to the right of the real one and the two images were displayed in alternating vertical stripes, almost as thought you were looking through vertical blinds. There were also 4 or 5 thin vertical stripes that were flashing as though video was being displayed though them like it used to if you used an older monitor with a new system that couldn't display things properly. At that point, there was no further boot progress.
In order to do a bit more troubleshooting, I booted the system with a live Linux CD - it booted and ran OK. I then tried installing Ubuntu. It started and then the screen went wonky again, with pixellating lines all over. I then repartitioned it, ran scandisk on the hard drive overnight (no errors), and reran the recovery process. Same shadow image when the XP splash screen appears - and it does this both during the ordinary booting process as well as during an attempted safe mode boot.
As I was typing the above, I remembered one other thing I meant to try. I reset the BIOS to default values and reran the recovery process - still a messed up WinXP splash screen after the progress bar makes 2 or 3 passes.
If anyone has ideas, I'd be grateful for the help.

Inaccessible boot device Windows 8

Hi!
My laptop was supposed to restart after windows updating. Instead of that bluescreen appears and says 'inaccessible boot device'. I've changed SATA Controller Mode Option to Compatibility and it still doesn't work. I also cannot open safe mode. Tried pressing F8, shift+F8, Fn+F8. Nothing works.
Please help me.
Thank you!

hi jumanjirose,
It's possible that one of those Windows Updates corrupted some of the Windows system files, causing the BSOD error. If you didn't create a recovery drive using this method, try one of the following:
Option 1:
Enter Push-Button Reset (PBR) mode - this is like a recovery environment to restore the pc from a previous working state. To do this, hold the power button while Windows 8 is loading up - the one where you see the white dots goes in circles (you need to do this twice). If successful, Windows will run startup repair. If it can't repair the error, you'll see this screen:
From here, click Advanced Options > Troubleshoot and you can:
a. Boot from the Last Known Good Configuration
b Boot into Safe Mode
c. Do a System Restore to restore Windows from a working state
d Refresh your Windows 8 PC or Reset windows 8 (note that this will wipe the computer clean)
Option 2:
If Push Button Reset doesn't work, follow this guide on how to enable legacy Safe Mode. When done, you should be able to access Safe Mode / Last Known Good Configuration by pressing F8 on startup or perform the PBR options above.

U330 Bios Update Issue, no boot device

Hi guys,
just wanted to let you know, that after updating to the latest bios firmware, my U330 said, that it could not find any boot devices.
The solution is pretty straight forward, just enter the bios (which is Fn + F2, even if you changed the Fn thingy before). I think, the only thing I changed was, using legacy instead of UEFI and that worked. Kinda strange since especially the windows 8 bootloader should support uefi.
Just wanted to let you guys know, in case you experience the same issue.

My mistake. The solution with changing the boot menu is correct.
To enter the BIOS is necessary to use a NOVO button. I used "reboot into BIOS" via Windows or the shortcut F2 during startup. Unfortunately, this method is wrong.
Solution: It's necessary to use the NOVO button to enter the BIOS.
