There's two ways to do it.  1) Boot off the rescue CD in single user
mode, then:

	# chroot /mnt/sysimage/boot
	# grub-install /dev/hda
	# exit (leaves the chroot environment)
	# exit (exits the rescue boot)

2) Use grub, but the easier sequence is:

	grub> root (hd0,0)
	grub> setup (hd0)

That assumes that the the stage1 loader is in /boot/grub and that /boot
is NOT a separate partition.  If you're not sure, use the sequence:

	grub> find /boot/grub/stage1
	grub> root (whatever-the-find-command-displays)
	grub> setup (hd0)
