what is exactly that you are doing to reinstall lilo?
i don't use ubuntu, but generally:
you should mount your original root fs on, say, /root
mount --bind /dev /root/dev
mount --bind /proc /root/proc
mount --bind /sys /root/sys
chroot /root /sbin/lilo

looks like your initrd is hosed
check that lilo is pointing to a correct initrd and/or regenerate
initrd. (no i don't remember the debian way to regenerate initrd)
