Probably LILO. It's configuration file is easier to read (but it's a matter of personal taste).
What you need to add to /etc/lilo.conf:
Replace /dev/hda1 with the right partition name (/dev/hda1 is first primary partition on primary master disk, probably it's the one you need to use). Save the file and run 'lilo' (both edition and running lilo should be done as root). Then reboot to see if it works.
