Hmmmm try this as another way of acccessing lilo:
Gain root access
Code:
su -
Mount the Knoppix HD install partition
Code:
mount -t ext3 /dev/hda5 /mnt/hda5
Chroot into the Linux partition:
Code:
chroot /mnt/hda5 /bin/bash
Then run lilo
Code:
/sbin/lilo
If either the chroot fails or the lilo fails, then there is probably something wrong with the partition table.
