removing stuff from MBR implies you might not be able to boot the
machine, so make sure you can still boot from floppy or cdrom or network
or ??? ( remove that target disk out of the boot sequence in the bios,
than remove stuff from the mbr )
root# grub
grub> uninstall ( i think it works donno )
-- or --
root# lilo -U
-- or --
#
# important ... dont make any tipoe's w/ dd
#
root# dd if=/dev/zero of=/dev/hda bs=512 count=1
-- or --
boot into dos mode
A:> fdisk /mbr
than boot up from floppy or other boot media and
re-install whatver boot loader ( grub, lilo, syslinux, .. ) you want
