Boot with either Ubuntu/Gentoo/Arch/Knoppix installation/live CD.  Anything will do, but it has to be reasonably up to date.

Open a shell and become root.

Assuming your root partition for Arch is /dev/sda1 and you are booting from /dev/sda (Adjust to your setup)

# mount /dev/sda1 /mnt
# mount --bind /dev /mnt/dev
# chroot /mnt /bin/bash
# grub-install /dev/sda
# exit
# umount /mnt/dev
# umount /mnt

Reboot and good luck.

If you are getting kernel panics,  we are out of the boot loader territory. (Unless the root device is wrong in menu.lst)

To help with this I will need some more info. I am especially interested in the blabla bits.

What does the 5 lines preceding the kernel panic say?

Re: Help with GRUB[ok]->kernel panic[ok]->filesystem check failed[&nuked]

Thank you, exactly what I needed.

Can be two things:

Grub specified the wrong root file system in menu.lst.

Try appending root=/dev/sda? to the grub boot command for arch (Replace ? with your arch root partition)  If that fixes it,  it was menu.lst in Ubuntu that broke it.

Second posibility: Grub did not specify the correct initrd image for arch.

Try specifying initrd as /boot/kernel26.img to the Grub boot configuration for arch.

It can also be both, then specify both,  I doubt it and suspect the second scenario.

This should get you booted after fiddling a bit.  Please re-run grub-install from the arch instance.

This site gives detailed instructions on how to make grub fly:

http://www.linuxforums.org/forum/linux- … -grub.html

Good luck.  I hope this fixes it for you.

Re: Help with GRUB[ok]->kernel panic[ok]->filesystem check failed[&nuked]

Yes  replaced:
root=/dev/sda4 with root=/dev/sda5
that booted ubuntu and that was funny

So then i tried 1 same panic.

And then 2. No panic -> Yeahho...But filesystem check failed. Cold this be a zero-length partition? "please repair manualy".
That gives me arch root shell.
And i do not know what to do???

Oh boy.  At least there is progress.

In the arch root shell.  Run grub-install.  This will install the arch version of grub, which, if we are just a little bit lucky, will make all these problems go away.  It can break grub too, in which case, pop the cd in and try and follow my instructions earlier in this saga about re-installing grub.

If not.

What filesystem is giving the problem? /   /home /var etc. 

If its not root,  try fsck.[jfc|etx3|reiser]  on the broken filesystem and reboot. (Please choose the appropriate filesystem. 

If its root, the best option is to boot the ubuntu lifecd, open a terminal, become root and then go fsck.[....] on the filesystem.

That should get you to boot it, which will allow you to run grub-install and hopefully sort the problem.

Nothing helped so after I was boried with this I edited rc.sysinit  quoted some lines about filesystem checking and everything now ok.
