install lilo pakcage from your distro CD, though I recommend GRUB.
dd if=/dev/hda? of=/mnt/c-drive/bootsect.lnx bs=512 count=1
You'd be grabbing it from the floppy (/dev/fd0 ?) but it would be similar.
That won't work if you extract the bootsector from the floppy..unless someone can prove me wrong.
