With a -proper- existing MBR, it doesn't matter, since it will still
pass boot off to the proper partition. But when you install an MBR
partition manager that overrides the standard MBR code, you must also
then uninstall it when you want to revert back to an OS that knows how
to boot with a normal MBR.
