    My Seven Steps to Lilo Heaven

    (Assuming sarge or later for nano)

    1. Boot up knoppix (or any recovery disk) and open a shell.

    2. Create a mount point ( `mkdir /repair` )

    3. Mount your root partition ( `mount -text3 /dev/hdd2 /repair` for me )

       * If /boot and/or /etc are separate partitions, mount them also
                  ( /repair/[ boot|etc ] )

    4. Switch to the hard disk installation ( `chroot /repair` )

    5. Check for the correct boot files ( `ls /boot` )

    6. Check the lilo configuration ( `nano /etc/lilo.conf` )

    7. Write the MBR ( `lilo` )
