You can also do, from either a Linux install or from one of the many
Linux "emergency recovery" distros (like Tom's Rootboot or the Linux
Bootable Business Card or something like that):
dd if=/dev/zero of=/dev/hda bs=512 count=1000
Which would overwrite the first 1000 blocks of hda (change as
appropriate) which should completely blast out the boot blocks and
partition table.
