Re: lilo- from Sarah
when you boot from your CD, you have to mount the root partition of your
debian installation. Your root partition depends on your setup, but try
the first "Linux Native" partition that has an asterisk in the "Boot"
column of the output of `fdisk -l`.
Try (as root)
# mount -t ext2 /dev/<your_root_partition> /mnt
# vi /mnt/etc/lilo.conf
The LI output of LILO suggest, that the second stage boot loader (okay,
never mind :) was loaded, but could not be executed. Make sure, that
your lilo.conf file looks correct and then run /sbin/lilo to re-install
lilo. Oh, btw, you will have to copy /mnt/etc/lilo.conf to
/etc/lilo.conf, because otherwise the copy from the CD will be used and
not your new version.
man 8 lilo, man 5 lilo.conf, /usr/doc/lilo/Manual.txt.gz
