Actually, you may also need to run "grub-install hd0" or some such
from within "chroot" *if* (as seems to be the case) the original grub
installation is not working properly.

The main difference (from a user's perspective) between "lilo" and
"grub" is that you do not need to re-run "grub-install" after editing
the /boot/grub/menu.lst file ... unless:

1. Your current installation is SNAFU (your current situation).

2. You plan the erase the partion from which "grub" currently boots.

Grub sometimes manages to recover pretty well even in case (2) as long
as it is in a "standard" location on *some* Linux/BSD-ish partition.
