[SOLVED] Grub error 22. I reinstalled grub from live cd but error still there.

[papafreebird]

My grub got messed up. Now I am trying to fix it. I reinstalled it using the info posted here

After reinstalling grub twice I still get error 22 and do not get the menu offering which OS I want to boot into.

here is my fdisk info

Any help would be appreciated.

Since you tried the grub howto and it didn't work you may have to get Super Grub Disk and try that.

Added: The error definition for 22 is:

# 22 : "Must load Multiboot kernel before modules"

This error is returned if the module load command is used before loading a Multiboot kernel. It only makes sense in this case anyway, as GRUB has no idea how to communicate the presence of location of such modules to a non-Multiboot-aware kernel

I believe this is usually some type of configuration file error although it doesn't seem like that from the definition.

[caljohnsmith]

Just curious, but where did you find that Grub error definition, phidia? I believe that a Grub error 22 is:

Error 22 : No such partition
This error is returned if a partition is requested in the device part of a device- or full file name which isn't on the selected disk.

See the online Grub manual.

Papafreebird, are you getting that error when you select an OS in the Grub's menu, or do you get that error before you even get the Grub menu? How about booting your Live CD, open a terminal (applications > accessories > terminal) and do the following:

sudo mount /dev/sdb2 /mnt
cat /mnt/boot/grub/menu.lst

Also, do you know which HDD you are booting from on start up?

[papafreebird]

I get the error before seeing any menu. It just says something like


Getting Grub stage 1.5
Loading Grub...
Error 22
and then just stays there.

I'll reboot the live cd and post the info you are requesting.

If you both think that super grub will be worth a try then I might try that also.

Will post back soon.

Thanks to you both for help.

[caljohnsmith]

OK, I think I know what might be going on. When you boot your Live CD, please also post:

sudo grub
grub> find /boot/grub/stage1

So was Grub working before--were you able to boot Ubuntu OK? Or has it never worked yet? And did you just recently add one of those HDDs (maybe the sdc drive)?

[papafreebird]

I can tell you that without booting to the live cd.
hd(1,1)

What happened was I recently screwed up my ubuntu install royally. It was working just fine then I screwed some things up so I just reinstalled 8.04 from cd. Now I have grub problems.

[caljohnsmith]

Can you change the BIOS boot order so that your Linux HDD boots first? If you can do that, it would be ideal, and we can set up your Grub accordingly. If you can make the Ubuntu HDD first to boot, then do the following so that you install Grub to its MBR (master boot record):

sudo grub
grub> root (hd1,1)
grub> setup (hd1)
grub> quit

Then all you will need to do is modify your menu.lst to get things working, but let me know if you can do the above first.

[papafreebird]

Okay my bios would let me set my linux drive to be the first hard drive booted so I set it that way then installed grub to hd1 as per your instructions.

What do I need to change in my menu.lst file?

my menu.lst file

title		Ubuntu 8.04.1, kernel 2.6.24-19-generic
root		(hd1,1)
kernel		/boot/vmlinuz-2.6.24-19-generic root=UUID=f3f4cf8d-9bd6-4092-a6d9-2d4d55f11c49 ro quiet splash
initrd		/boot/initrd.img-2.6.24-19-generic
quiet

title		Ubuntu 8.04.1, kernel 2.6.24-19-generic (recovery mode)

Since you were able to change your BIOS to boot your Ubuntu drive, you have to change your menu.lst because your Ubuntu drive is now (hd0) or the boot drive, and not (hd1) or the second drive in the BIOS boot order. So all you need to do is open your menu.lst:

sudo mount /dev/sdb2 /mnt
gksudo gedit /mnt/boot/grub/menu.lst

And change all the "root (hd1,1)" instances to "root (hd0,1)". And one last detail, near the top of the file change the "#groot=(hd1,1)" to "#groot=(hd0,1)".

Also, your Windows will be on either (hd1) or (hd2) now that Ubuntu is first to boot. So replace the Windows entry in menu.lst to the two following entries:

title		Microsoft Windows XP Professional (hd1)
root		(hd1,0)
map        (hd0) (hd1)
map        (hd1) (hd0)
makeactive
chainloader	+1

title		Microsoft Windows XP Professional (hd2)
root		(hd2,0)
map        (hd0) (hd2)
map        (hd2) (hd0)
makeactive
chainloader	+1

One of those should work, and when you figure out which one it is, you can delete the other entry afterwards. Let me know how it goes or if you need more details/info.

caljohnsmith, You're right I pasted the wrong error definition-sorry.
I'm not sure how that happened. Good that you caught it though.
