GRUB2 Basics
Hmmmm....
After reading and re-reading the wiki on GRUB2 ,the resource links at the bottom of the page and googling I'm still none the wiser as to why my GRUB2 upgrades fail (two attempts). So I'd like to pose a few basic questions i'm unsure of. I find the available information sparse to say the least and confusing. eg: my undertsanding is the partition numbering has changed from starting at zero to starting at one. With NO changes to the disk numbering system ,though after googleing I found on a gentoo forum it's the other way around?? The disk numbering need to be changed!! So after my little run-around it would seem to make sense to to gather some answers to some simplistic questions.
Maybe this will end up a little reference point and help some people.
All definitive answers I will add to the wiki: my way of giving some back to the Arch community.
If you have questions you are unsure of about GRUB2 or feel will help other's (regardless of wether you know the answer or not) 'post' them here ,i'll endeavour to maintain (and gather) info *if* this is conceived as a valuable idea. Please provide known answers and/or any 'best practice' solutions you are aware of - and must be consistent with the Arch way of doing things.
So for starters...
Where's the official GRUB2 FAQ and doesn't that have the answers?
http://www.gnu.org/software/grub/grub-l … aq.en.html
Must GRUB2 be edited with 'nano' or similar in place of a text editor?
Is it ok to hack grub.cfg with a text editor ie: Gedit?
Does GRUB2 require install where only / exists or does it work ok where users have a seperate /boot partition?
Is GRUB2 case sensitive?
Can GRUB2 support NTFS?
Does GRUB2 have issues with any special characters and/or character sets?
In a live system I can type # grub and then configure ,where has it gone in GRUB2?
Must I run mkinitcpio to (create new image)?
When I borked my system I could goto GRUB find /grub/stage1. Why is the 'find' command
not present in GRUB2 ?
Can GRUB2 work with the existing kernel-image that GRUB supports without intervention?
Does GRUB2 have issues with 64bit?
I followed the wiki rebooted and got kernel panic ,cant sync ,cant find init! - what do I do next?
Should I crack open a 4X ,boot half-life2 and forget about all this stuff? lol
Save the latter I guess going straight to the dev(s) is one idea though they're probably busy at the moment ,i've looked around for answers to the above though it's all bits n pieces hence this... !
Err. You couldn't find the GRUB 2 FAQ?
http://www.google.com/search?q=GRUB2+FAQ (works with a space between grub and 2 as well)
First result you see there (or second). As they say (and link) the wiki has the rest of the info.
Rather vampirish IMHO.
Disk numbering has changed only slightly.
Here is a great page with a ton more answers: http://wiki.archlinux.org/index.php/GRUB2
1.) nano is a text editor.
2.) They don't recommend it, but yes. The preferred way is to edit scripts which themselves build grub.cfg. http://grub.enbug.org/grub.cfg
3.) GRUB usually installs to the MBR. You set the boot and root partitions yourself. This hasn't changed. In other words, yes.
4.) What do you mean? In what? Does it matter? Install and find out. I would guess yes, since that's the Unix style.
5.) http://grub.enbug.org/CurrentStatus
6.) Considering that one of the most hyped features is not requiring ASCII like the old GRUB, meaning UTF-8, graphics, etc.? http://grub.enbug.org/AboutInternationalization
7.) http://grub.enbug.org/Manual http://grub.enbug.org/UseCases http://grub.enbug.org/InstallingGrubNatively http://grub.enbug.org/CommandList
8.) Dunno. Try and see.
9.) http://grub.enbug.org/CommandList (Look carefuly...)
10.) I think so. I'm not quite sure what you mean. Again, try and see.
11.) No.
12.) Wait, so you know about the wiki? Arrgh... Anyways, this probably means you didn't load the initrd, or set it up wrong (without the modules necessary to load your filesystem). Please post all relevant info (mkinitrd config, filesystem used for root, grub.cfg and commands used, etc...)
90% of all that was just me effectively using Google. If I could do it, so can you. Please search next time I almost didn't reply - there's not much incentive to reply to posts like this when there's others to help too.
Hope you get your issue resolved.

[SOLVED] Can't boot Windows 8 using grub2. invalid EFI file path
English is not my native language. Please excuse typing errors.
I have just successfully installed Arch linux with grub2 as its boot manager. I
followed the arch beginner guide. I've used grub before and I'm familiar with
it, so chose to use grub instead for efistub. I installed os-prober and
ran grub-mkconfig to create the grub.cfg file. The problem now is that I recieve
an error when I try to boot windows 8. I have two drives (/dev/sda and /dev/sdb)
and I believe both are EFI-systems.
However, it's not very important for me to use grub, so if booting into windows
8 is easier using efistub, I will try that.
The computer is ASUS ux32vd with a hybrid disk with 25GB on the SSD and 500GB on
the hard drive. I believe the SSD part is used by Windows.
This is the first error I recieved when I tried to boot windows.
error: can't find command `drivemap'.
error: invalid EFI file path.
Press any key to continue...
Then I tried to follow this post
https://bbs.archlinux.org/viewtopic.php?id=150183 and made a new boot
entry "Windows 82". And I got a new error:
error: unspecified search type.
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found
Press any key to continue...
Here are some command line outputs.

I gave up trying to make grub work, so I uninstalled grub and deleted all the grub files I could find.
# pacrem grub-efi-x86_64
# rm -fr /boot/grub
That last one I came to regret later on. So I installed rEFInd using the archlinux beginners guide. When I then tried to boot into windows It told me that /boot/grub/x86_64-efi/normal.mod was not found. I then reinstalled grub-efi-x86_64 and copied /usr/lib/grub/x86_64 to /boot/grub. Now everything works fine.

8 is easier using efistub, I will try that.
The EFI stub loader is a Linux-only boot loader; however, it is possible to use the EFI stub loader in conjunction with a separate boot manager, such as rEFInd or gummiboot. In such a configuration, you'd use the boot manager to select the OS to boot (Windows or Linux, and possibly the specific Linux kernel), and the boot loader (the Windows loader or the EFI stub loader built into a specific kernel) will then take over booting the OS. In Arch, this is often easier to configure than is GRUB, since GRUB is very complex and its automated tools to help with setting things up often get it wrong.
This is the first error I recieved when I tried to boot windows.
error: can't find command `drivemap'.
error: invalid EFI file path.
Press any key to continue...
The "drivemap" command in GRUB is generally used when booting a BIOS-mode boot loader, and in fact your "Windows Recovery Environment (loader) (on /dev/sda2)" and "Windows 8 (loader) (on /dev/sda4)" GRUB entries are both built as for BIOS-mode Windows installations -- but the fact that your disks both use GPT means that Windows won't boot in BIOS mode on your computer. (This is one of the many things that the GRUB setup scripts can get wrong.)
Then I tried to follow this post
https://bbs.archlinux.org/viewtopic.php?id=150183 and made a new boot
entry "Windows 82". And I got a new error:
error: unspecified search type.
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found
Press any key to continue...
Both your "Windows 8" and "Windows 82" entries refer to an EFI boot loader file called EFI/Microsoft/Boot/bootmgfw.efi on your EFI System Partition (ESP). This should be correct, but your Boot Info Script output doesn't show any evidence of such a file. Sometimes Boot Info Script misses such things, so you may want to check it just to be sure. Your ESP is /dev/sda1, and it looks like it's being mounted at /boot/efi by default, so check for the /boot/efi/EFI/Microsoft directory tree, and for /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi in particular. If that file isn't present, then something is wrong -- perhaps you mistakenly erased the ESP when you installed Linux, thus wiping out the Windows boot loader; or perhaps the file was accidentally deleted somewhere along the way. (Note that on FAT, which the ESP uses, case is irrelevant, and in fact case varies between the filenames reported by Boot Info Script and what's recorded in your configuration files.)
You do have another boot loader file that may be a duplicate of the Windows boot loader: EFI/BOOT/bkpbootx64.efi. This filename is generally created by Ubuntu's "Boot Repair" tool, which IMHO can do as much harm as good, especially on a system that's not booting Ubuntu. If you ran this tool, though, it's conceivable that bkpbootx64.efi is a copy of the Windows boot loader, so copying it to EFI/Microsoft/Boot/bootmgfw.efi might get things working. OTOH, the Windows boot loader relies on other files to do its job, so if they're not present, copying the Windows boot loader to its original location won't be sufficient.
If you can't get things working based on the preceding suggestions, I recommend you run a Windows repair tool. These are accessible from a Windows recovery disc. Such disc images are readily available on the Internet, but I don't happen to have any links handy. Try Microsoft's own site; images obtained from random third-party sites might contain malware. Once you've done this, chances are the computer will boot directly into Windows. You'll then need to either restore GRUB as the default boot loader or install another boot loader or boot manager. You can use the Windows "bcdedit" command to do the former, as in:
bcdedit /set {bootmgr} path \EFI\arch-grub\grubx64.efi
You'll need to type this from an Administrator Command Prompt window. -
[Solved] grub2: file not found but booting fine
I just ran grub-mkconfig to update my grub.cfg because I installed E4rat. But now I have a problem: Every entry in grub2 can be booted and E4rat really boosted my boot process so actually everything is fine. But while grub2 is loading it says something like:
Grub 2 is loading...
Welcome to Grub 2!
error: file not found.
error: file not found.
error: file not found.
Now grub shows up and everything is as it should be. When I select Arch it again says "error: file not found." three times and continues with a normal boot process. So basically it's nothing that would brake my system but something seems not right and that's just a huge annoyance.
Here's my grub.cfg just in case:

Last edited by retzu (2012-04-16 14:16:02)I have the same error message as in the first post. "error: file not found" listed three times when I first choose Arch from the Grub2 menu. The solution linked to by the.ridikulus.rat would not seem to apply as I do not have the locales en* in /boot/grub/locale BTW, I am in the US. The system does boot though.
I just fixed this a few seconds ago and was going to post how, basically I just did "cp /boot/grub/locale/[email protected] /boot/grub/locale/en_US.mo" which seem to do the trick, the reason I didn't fix this sooner is the error only stays up for a very small fraction of a second making it hard to read.
# ls /boot/grub/locale
ast.mo da.mo fi.mo hu.mo it.mo nl.mo ru.mo uk.mo zh_CN.mo
ca.mo de.mo fr.mo id.mo ko.mo pl.mo sv.mo vi.mo
EDIT: I get the same three "error: file not found" messages when I boot Fedora (a multiboot system). This is with grub2 installed from Arch Linux.

[VIDEO TUTORIAL] Installing Arch Linux on GPT/LVM/GRUB2
Hello everyone,
I've recently switched over from running my machine on LVM with a MSDOS partition style, and I was tired of the limitations of it. Such as 4 primary partions or 3 primary and 1 extended. It was also hindering my flexibility since I had to make 1 primary partition that was /boot, which forced me to make an initram image if I wanted to put my / inside of the LVM. The only way I could truly fix all my problems was to move away from GRUB-Legacy (Which I love since it's so easy to configure) over to GRUB 2(Which is not as bad as I thought it was).
I made this video to help people trying to do this combination. I also included the links to further information in the videos' description. It contains a link to GRUB 2 Architecture and moving over to GRUB (on IBM's site), and also ArchWiki resources for further reading.
I hope you enjoy it.
http://www.youtube.com/watch?v=69X9ZYA41xU
After you finish doing this, you will end up with this style:
GPT Partition Layout w/ Protective MBR.
/dev/sda1 - BIOS Boot Partition
/dev/sda2 - Linux LVM (arch is name of LVM)
--> /dev/arch/boot - ext2
--> /dev/arch/swap - swap
--> /dev/arch/root - ext4
--> /dev/arch/home - ext4As a complete newbie to partitioning on Linux I'd like to say how grateful I am to for making this.
You've kept it clear, clean and simple which I appreciate.
As most of my ventures into installing Linux is usually accompanied with a graphical installer a great deal of this is fairly alien. It could be nice to have a wiki entry just laying out a few examples for partitioning and setting up arch in various simple and exotic ways.
Again, thank you for this contribution. (While I quickly transcribe the steps in your video and ready the 'man' command)

Cannot make GRUB2 use (perfectly-working) max resolution
My arch installation is still in its infancy console-only (no X installed) and it is perfectly working @ 1920x1200 native resolution on a Dell Inspiron 9400 E1705 with ATI Radeon X1400 @ 1920x1200 (aka WUXGA mode) with the xf86-video-ati driver installed and the corresponding RADEON module on (/etc/mkinitcpio.conf) for early KMS start.
cat /sys/class/graphics/fb0/virtual_size ... reports 1920x1200
However, when I boot and enter GRUB2 console and run VBEvideo to show all supported resolutions it shows preferred-resolution=1920x1200 but current-resolution=1600x1200 and there's no entry for the native 1920x1200 resolution -the closest one is 1920x1440 which does not fit my laptop screen; which perfectly explains why GRUB2 is using what is currently using.
Obviously, switching the associated GRUB_GFXMODE entry from =auto (default) to =1920x1200 in (/etc/default/grub) and then running grub-mkconfig --output /boot/grub/grub.cfg does not make any changes: it always ends in 1600x1200 for the boot screen.
GRUB2 works fine. Arch works fine too. Only problem I am trying to fix is some screen flash when GRUB2 turns control to linux and thus is how I discovered the GRIB2 entry for video.
Any clues why GRUB2 is not listing/supporting a video mode that is obviously supported on this particular laptop and/or linux installation ?Although I still can't find conclusive evidence on this matter what you tell me seems to be right: for what I learned so far GRUB2 loads some very-basic VESA driver and maybe this is the key issue here for non-standard resolutions -mine @ 1920x1200 (widescreen) sure it is not.
Anyway thanks for your help -
I was able to snag a Dell 1703FP Monitor and was very pleased to discover that I could rotate the monitor by 90 degrees clockwise (or pi/2 if you prefer radians). I have been able to get the initial boot console text oriented correctly by changing my grub.cfg boot arguments:
linux /vmlinuz-linux root=UUID=fc122248-ba87-4c61-89e6-ad24f22bfcbc ro quiet fbcon=rotate:3
This, however, does not work on Grub itself. Grub remains in a horizontal orientation. Although this isn't such a big issue (after all, I only see Grub each time I reboot, and only for 3 seconds), it's just one of those "little things" that irks me. I have tried setting the framebuffer resolution in grub.cfg as such:
set gfxmode=1024x1280x32
This does somehow set the resolution correctly, (this is a 1280x1024 monitor in horizontal mode) but it is still not orientated to my needs. Is there any settings that I am missing to rotate Grub's output, or is this a feature that is not yet implemented into Grub? Is there an alternative bootloader that supports rotated monitors?
This thread is very similar, except it is more concerned with SLiM login manager (which I have the same issue with, too, but that can be saved for a later day.)
Just in case, video card is GeForce FX 5200, and here is my 10-monitor.conf:
Section "Monitor"
Identifier "Monitor"
EndSection
Section "Device"
Identifier "Device"
Driver "nouveau"
Option "RandRRotation" "on"
Option "Rotation" "CCW"
EndSection
Section "Screen"
Identifier "Screen"
Device "Device"
Monitor "Monitor"
Option "RandRRotation" "on"
Option "RandRRotation" "CCW"
EndSectionLastebil wrote:
Spent some basic time with this, exploring the possibilities with the vbe graphics modes and the "vga video driver," read some config details about booting into a rotated buffer / different graphics buffer, but finally settled on looking directly at grub2's main documentation for some hints.
It's there I realized that since grub2 is targeted for many platforms, not just intel, there are some stumbling blocks; for example one of the non-intel consoles only supports ascii. Serial can have one of three methods for drawing, etc. In short: this would be very specific to the vbe driver, and it's not in the code. I don't know that there would be that much use for it, given that there _is_ support for theming.
I also considered trying some of the fbcon ideas, but then realized that is only the console after booting - and I don't think there's a fbcon console driver in grub2 based on what I looked at codewise. (I could be wrong, as something led me that way for a few "patch commits" but I eventually decided it wasn't really adding the fbcon interface, just launching to it with gfxpayload.)
I'm not sure what it will take to make a theme that is "rotated." It may also suffer from "90 degree keyboard syndrome" (where you press the "down" key, and the cursor moves to the right.) Still, I'd think that is the faster way of doing this, rather than trying to add this support to the VBE code.
Since I spend very little time on that screen in reality, I think I can live with it for today. (I'd been wondering this for some time but hadn't attempted to fix it until today.)
My goodness! Someone has REALLY been doing his/her homework! I kinda feel bad that you are doing this much work, especially for such a small quirk. But if it satisfies you, I applaud thee
Lastebil wrote:Since I spend very little time on that screen in reality, I think I can live with it for today.
I can totally agree with you there. Since I'm in the middle of academics I haven't found that much time to be tinkering. That being said, when I do get free time, I'd start looking at the grub code itself, as I have found no way using kernel settings or other programs (fbcon, xrandr), so I'd assume changing grub code itself would be the only solution. This seems like a daunting task, especially for someone like me who is not a professional programmer by any means, but it seems like a fun project that would give me the incentive to learn about low-level programs like this (I consider myself a Linux hobbyist, calling me a scripter would be stretching it.)
If you do decide to continue working on this (by no means am I demanding you to) I'd love to see what kind of stuff you are doing and learn from someone who (clearly) knows his stuff. Thanks for your input! -
GRUB2 Graphics Mode doesn't work
I removed old grub and installed grub2 and everything went smoothly, I even got the 1024x768 resolution on grub menu. Then I slightly changed /etc/default/grub and when I again generated grub.cfg, I always get plain console resolution (80x24).
Here is my /etc/default/grub file. I tried both gfxmode and vbemode options, but no success.

How to set native resolution in GRUB2 - Intel HD graphics
Hello.
I want to set 1440x900 in GRUB2.
I use Intel HD 3000 integrated graphics with CPU i5 2500k.
I use grub2-efi-x86_64 1:2.00beta4-1.
Hwinfo from running Arch Linux shows:

I tried these settings in /etc/default/grub:
GRUB_GFXMODE=auto #running with 800x600 resolution
GRUB_GFXMODE=1440x900x24 #not working: still running with 800x600 resolution
but always GRUB2 run with 800x600.
Any ideas how to set 1400x900 in GRUB2? Is it even possible?

hwinfo shows your desired resolution, so it's in the vbios, which means you don't need i915resolution. That one is to program resolutions that are *not* in the vbios already.
But as to why grub2 won't work, idk, I'm staying away from this over-engineered piece of... something... that just happens to also include a bootloader . Could be your syntax is wrong. Have you already tried 1440x900@24 or 1440x900-24 or simply 1440x900 or 0x037f?
Edit: Gah, GRUB_GFXMODE isn't for grub.cfg, it's for /etc/default/grub. If you're configuring grub.cfg directly, it's 'set gfxmode=1440x900x24'. See what I mean with over-engineered piece of something?
Thanks for tips. Yes, I edited /etc/default/grub not grub.cfg. Everytime when I finish editing /etc/default/grub I execute
grub-mkconfig -o /boot/grub/grub.cfg

GRUB2 still running at 800x600. Any ideas? -
Hey Peeps,
So I was playing around earlier today with a GPT/LVM/GRUB2 install. I've read up on it a bunch, as well as the Arch GRUB2 & LVM wiki's and a video on YouTube. Things seem to go well up until the part of doing grub-mkconfig... it doesn't work.
The video tutorial I watched showed it finding the linux and initrd images, but mine doesn't. So needless to say, if I reboot it crashed. I've gotten it to load GRUB2 and start-up if I just delete the entire grub.cfg file and make my own basic one, but this seems much different than other people's experience.
Why is grub-mkconfig not working right? It creates a config file, but saves it as grub.cfg.new instead of grub.cfg. It also doesn't use the contents of /etc/grub.d/custom_40 like the video tutorial shows either.
Thanks for any help!
Here's the video tutorial I was following.
http://www.youtube.com/watch?v=69X9ZYA41xUYou're right... crash isn't the right word. I believe, from memory, the error was something about fd0.
I know I can copy the grub.cfg.new to grub.cfg, just find it odd that none of the other tutorials or installs I've read about discuss doing this.
Here's a transcript of the video taken from https://bbs.archlinux.org/viewtopic.php?id=133170

One wallpaper from GRUB2 boot, to login (wihtout flickering)
I've been usage-testing arch for some time on my netbook-esque laptop (ultraportable?), and I'm happy to say that I have decided to stick with the beast! (Seriously, I lost track of time tweaking my system last night and went to bed in the wee hours of the morning!)
I've decided to take up the task of creating a "seamless" boot setup, while keeping things light -- basically making one background image stick to the screen from the bootup to the start of the x session while trying to avoid showing any. My setup is as follows:
1-- GRUB2 - used to set initial resolution (1366x768x24) and wallpaper (wallpaper.tga)
2-- **** I have all the problems here. I may put Splashscreen-solution: Splashy? fbsplash? Plymouth? ****
3-- SLiM with a modified theme using (a link to) wallpaper.png
4-- Openbox session with wallpaper and desktop icons set by pcmanfm
Currently, after selecting my grub entry, the wallpaper shamelessly disappears and is replaced by a black screen with some arch logos and console output for a moment before abruptly switching over to the all-black console output where all of the boot info is shown. Then it goes to tty login, then SLiM starts up...
I recall 3 times the console output "flickers" and changes: after I leave grub, there's the console with the archlogos, then there's the boot output console, then there's the tty login that waits on SLiM to startup. Can I just set background.png/tga for all of these console backgrounds during boot? (I may possibly remove SLiM if I can do that...) Do I HAVE to install a bootsplash app (like splashy fbsplash or plymouth) to get this desired behavior? If so will those apps set my background during the tty login prompt while SLiM loads up?It's an old thread, but I can't see it has been solved. My try has been using the following setup: grub2, plymouth, systemd and lightdm.
I've tried to archieve this, using the following options:
/etc/default/grub:
The idea is to boot to tty7, the same as lightdm, so no VT switch makes things "ugly".
GRUB_CMDLINE_LINUX_DEFAULT="vt.handoff=7 quiet splash init=/usr/lib/systemd/systemd logo.nologo add_efi_memmap"
GRUB_GFXMODE=1280x800x32
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_BACKGROUND="/boot/bg.png"
Systemd:
Enable lightdm-plymouth.service unit and disable any other greeter (kdm.service, gdm.service, lightdm.service, etc.)
/etc/lightdm/lightdm.conf:
greeter-user=lightdm
minimum-display-number=0
minimum-vt=7
run-directory=/run/lightdm
start-default-seat=true
With this setup I'm getting all three flicks, so it's not working as I'd like. I'm using a Dell Latitude E4300 with integrated graphics (Mobile Intel® GM45). -
I had a problem with GRUB2, and I couldn't find an answer anywhere. Eventually, me and my Gentoo using friend found the solution.
Since I thought it would be useful for many users, I decided to write a guide describing how to deal with such situations. I wanted to add it to the wiki but I don't know how to edit wiki pages.
I would appreciate opinions and corrections and if someone could convert it to wiki format it would be great.
GRUB Rescue (GRUB2)
Since the MBR is too small for all of GRUB2 modules, just the menu and a few basic capabilities truly reside there. Most of GRUB2 stays on the partition it was installed from. The "MBR part" keeps a variable - "prefix" - which points to the partition and folder containing the rest of the program.
Sometimes, when you change the partition layout of your HD, the number of the partition which contains GRUB2 changes. Let's assume we installed GRUB2 from (hd0,7) or /dev/sda7, which is a logical partition inside an extended partition. Then we deleted /dev/sda5 and /dev/sda6, our /dev/sda7 became /dev/sda5. Now when the "MBR part" is looking for the rest of the program, it can't find it in (hd0,7) since such partition doesn't exist anymore. In this case, instead of showing the usual GRUB2 menu, you are being dropped to some sort of command line which is called GRUB rescue.
The easies way to fix this situation is to use another boot disk of some sort and reinstall GRUB2 again from the right partition. Such a boot disk is not always available so here is how to do it from GRUB rescue.
The number of available commands in GRUB rescue is really minimal. The only useful ones are "set" and "insmod". "set" sets variables, and "insmod" inserts new modules to expand GRUB rescue's capabilities.
Before we can start, we have to know the right number of the partition which contains GRUB2 in order to inform the "MBR part".
Assuming GRUB2 is installed in it's default location "/boot/grub", type
set prefix=(hdx,y)/boot/grub
where x is the physical HD number and y is the partition number.
Note: If (hdx,y) is a boot partition, you have to omit the /boot part from the path, ie type "set prefix=(hdx,y)/grub".
Now we want to expand the console capabilities so we insert a useful module. Type
insmod (hdx,y)/boot/grub/linux.mod
where, again, (hdx,y) is the right partition where GRUB2 was installed from and "/boot/grub" is the path to the installation directory.
This will hopefully bring you back to the standad (?) GRUB2 console.
Now in order to boot your OS, we have to type the regular GRUB2 command.
Here is an example of how to boot Arch Linux:
set root=(hd0,5)
linux /boot/vmlinuz26 root=/dev/sda5
initrd /boot/kernel26.img
boot
where (hd0,5) is the partition of your Arch Linux installation (not necessarily the same partition as above and it is probably different in your case).
If you have a boot partition, change the lines accordigly to something like that:
set root=(hd0,5)
linux /vmlinuz26 root=/dev/sda6
initrd /kernel26.img
boot
and again, change the numbers to fit your layout.
After successfully booting your Arch Linux installation, you must fix grub.cfg to the new partition numbers and then run
grub-install /dev/sda
or /dev/sdb or whatever fits your layout to reinstall GRUB2 and fix the problem completely.

Thanks. I didn't know about that.
@pointone
Thank you. So the key is <nowiki> </nowiki>, good to know.
I see that the article was merged nicely into GRUB2 wiki page. That's great!
There are two problems with the content though.
1) "The available commands in GRUB rescue can be listed by entering "help"."
This proved to be 100% wrong in my case. I couldn't use "help".
2) Whoever did the cut and merge, omitted the "set prefix" command.
I checked it about 10 times and if the prefix is wrong you can't use "insmod" at all even if the root variable is right!
Since "set prefix" is the core of the problem it must be included.
Otherwise, nice merge. -
[SOLVED] GRUB2 not loading on UEFI system
Hello!
I tried to install Arch Linux on a new Sandy Bridge-system with UEFI, but am not able to boot it from the firmware.
During the installation I choose not to install a bootloader and instead followed the instructions in the GRUB2 wiki page.
After the installation I'm not able to load GRUB2 by selecting the device in the UEFI firmware (MSI's Click BIOS).
It say's something like "reboot and select proper boot device, or insert boot media in selected boot device.".
I am however able to boot the system by running the EFI Shell and loading grub2 by entering the following commands:
fs0:
cd efi
cd grub
grub.efi
I can then continue to boot arch in the grub console using:
set root=(hd1,gpt4)
linux /boot/vmlinuz26 root=/dev/sdb4 ro
initrd /boot/kernel26.img
And arch boots fine. (more or less, but it starts).
I'm not sure why the firmware isn't able to load the grub efi application, while the efi shell is.
I'm now looking for help troubleshooting this issue, since i don't really know where to begin looking.

I'm not sure what to do with efibootmgr, it is installed and if I recall correctly was run by grub_efi_x86_64-install.
Anyway, here is it's output:
BootCurrent: 0004
Timeout: 1 seconds
BootOrder: 0000,0001,0004
Boot0000* SATA: SAMSUNG HD103SJ
Boot0001* SATA: Optiarc DVD RW AD-7260S
Boot0004* Built-in EFI Shell
Where 0000, the Samsung HDD is the device from which i want to boot.
Below is some additional output which may be useful:

Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
Name Quantity
and from the external flat file i get some characters for my quantity field. would my load fail? for standard dso and for write optimized?
NOTE: quantity field is a keyfigure defined as numeric.
and the load coming in has "VIKPATEL" for Quantity field and not numbers.
thanksHi Vik,
Yes, the load will fail.
May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
You can use transfer rule, or a clean up ABAP code in the start routine.
Hope this helps. -

Type Mismatch error while calling a Java Function from Visual Basic 6.0...
Hi,
I'm having a problem in calling the Java Applet's Function from Visual Basic. First, I'm getting the handle of the Java Applet and components of it using "Document.Applets(n)" which is a HTML function. I'm calling this function from Visual Basic. My code is something like this...
' // Web1 is IE Browser in my Form.
Dim Ap,Comp
Dim Bol as Boolean
Bol = true
Ap = Web1.Document.Applets(0).getWindow() ' \\ Gets the Parent Window.
Ap.setTitle("My Java Applet") ' \\ Sets the Title of the window.
msgbox Ap.getVisibility() ' \\ This will return a Java boolean ( true or false )
Ap.setVisibility(Bol) ' \\ Function Syntax is : void setVisibility(boolean b)
Here in my code , i'm able to call any function that which accepts Integer or String but not boolean. So, i m facing problem with Ap.setVisibility() function. It gives me a "Type mismatch error" while executing it. Can you please tell me a way to do this from Visual Basic !
I'm using Visual Basic 6.0, Windows 2000 , J2SDK 1.4.2_05.
Please help me Friends.
Thanks and Regards,
