Ok, i found a neater way for you to do that.. ;)

go to: http://www.lnx-bbc.org/download.html fetch the iso image.

boot with the image, log in as root. mount your partition, and chroot to it:
mount /dev/hda1 /tmp
chroot /tmp /bin/sh

If you have other filesystems you are forced to mount, you shouldn't 
really do this unless you have to. If you do this, you need to clean up 
before you go:
mount -a

Re-install lilo by running lilo.

Back out once again:
exit (exit back to lnx-bbc)
umount /tmp
sync (i like to play it safe)

shutdown the system and boot up without the bootable CD-Image.

That's the quick tour on recovering from a HD failure, there are better 
howtos for this, but if you are clever you should be able to do it with 
this.
