GRUB Error 11: Unrecognized Device String

This just popped out of nowhere. i tried reinstalling GRUB with a livecd but that didn't work. This is on a fresh install from last night. This morning just rebooted and BAM. The Windows option still works though..:rolleyes:

Heres my menu.lst

# (0) Arch Linux
title  Arch Linux
root  (hd0,2)
kernel /boot/vmlinuz26
root=/dev/disk/by-uuid/a9341d88-bf3b-4dfe-a46d-46c38b2c2224 ro
initrd /boot/kernel26.img

# (1) Arch Linux
title  Arch Linux Fallback
root  (hd0,2)
kernel /boot/vmlinuz26
root=/dev/disk/by-uuid/a9341d88-bf3b-4dfe-a46d-46c38b2c2224 ro
initrd /boot/kernel26-fallback.img

Whats wrong?

Re: GRUB Error 11: Unrecognized Device String

The kernel and root must be in the same line
Wrong:
kernel /boot/vmlinuz26
root=/dev/disk/by-uuid/a9341d88-bf3b-4dfe-a46d-46c38b2c2224 ro

Right:
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/a9341d88-bf3b-4dfe-a46d-46c38b2c2224 ro

Press "e" in your grub screen on any one

Go to the root line and press "e"

Go to its begining and type kernel /boot/vmlinuz26

Press Enter

Go to the previous line ("The one with the kernel in it")

Press "d" to delete it

Press "b" to boot

When your install boots, open the /boot/grub/menu.lst and delete the line break between the kernel and root line. Save the file.

enjoy

Thank you!

This happened to me on the first boot after installing. It seems that nano automatically put root on a new line when I added a vga setting. As I was editing menu.lst to remove the newline, nano tried replacing it several times!

I think I'll go and learn vi now.

Re: GRUB Error 11: Unrecognized Device String

I had the same problem, when you edit the kernel line, it word wraps the root= line. You just add your change, then backspace at the beginning of the line.

You can also just create a .nanorc file in your home directory and put in

set nowrap

and all will be well.

That's why it's safer to invoke 'nano -w' when dealing with system configuration files.
