[NMLUG] Argghhh!!! I hosed my MBR
You need to boot up from an install cd.
Then switch your virtual terminal ato get a prompt.
fdisk your partitions.
Then mount them. You will manually have to rebuild the directories if you
have mount points.
Then chroot to your partitions.
Then re-run lilo in the chrooted environment.
If you do not fdisk the partitions, your lilo will not work.
