Hi

Updated the firmware on a PERC RAID card as it was out of date and causing a monitoring error - Everything went fine but on the reboot the box now tells me it cant find a valid boot device - I am thinking maybe somehow the boot block on the logical disk is shot.

Can anyone advise me on how to rebuild the bootloader on lilo using a rescue CD?

I have not used lilo in while, but you should be able to boot the rescue CD and have it mount your partitions in /mnt/sysimage.

After you verify that the /boot and / are mounted there, you should be able to do:

chroot /mnt/sysimage

and then just do this from inside the chroot:

lilo

then exit the chroot and reboot
