In rescue, try to mount the root filesystem, and /boot if it is a
separate filesystem. Then chroot to the mountpoint of the root
filesystem ("chroot /mnt" or something), and do "grub-install
(hd0)" (the grub way of saying the disk) or "grub-install
/dev/sda" or /dev/sda1 or whichever disk/partition is the root
filesystem. I'm not sure if its more appropriate to install grub
on the disk or partition but I don't think it hurts to try both.
While the root filesystem is mounted you can also make any
corrections to the menu.lst if needed.
