Got kernel panic on my desktop: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Kernel panic by Peter A. Shevtsov, on Flickr

I don't know what to do. Please help.

Re: [SOLVED] Kernel panic on boot

Is this a new installation?

Please post the contents of

/boot/grub/menu.lst

if you are using grub-legacy.

Re: [SOLVED] Kernel panic on boot

No, this is no a new installation. I suppose this happened after kernel update. I do not use this machine quite often.

/boot/grub/menu.lst:

#(0) Arch Linux
title Arch Linux
root (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/f2a897fe-a6e2-43f3-85c6-8f72c997bc2b ro quiet
initrd /kernel26.img

#(1) Arch Linux
title Arch Linux Fallback
root (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/f2a897fe-a6e2-43f3-85c6-8f72c997bc2b ro quiet
initrd /kernel26-fallback.img

How can I run blkid if I have only GRUB-shell?

Re: [SOLVED] Kernel panic on boot

Perhaps you can try various grub entries for root=... one of them might get it started.

Run blkid from a live CD.

Before that, are you sure that your root partition is on /dev/sda1? If so, you might want to try root=/dev/sda1 in the kernel command line just in case the UUID is incorrect

Re: [SOLVED] Kernel panic on boot

Thanks to everyone, especially lilsirecho - Kernel Panics wiki page is really handy! I just reinstalled kernel and everything's got back to normal.
