Don't think I know offhand how to do that, but it probably involves at least
one of grub-install or fdisk. (I'm leaning toward the former.) I do know
that when you mess with booting _always_ have another bootable medium (CD,
DVD, thumb drive, USB hard drive, etc.) and know how to use it, because of
the elevated likelihood (and dramatic consequences) of mistakes.
