You don't say what boot loader you're using, but if you are using grub,
you can simply install the MBR to the second disk using the grub terminal.
Run grub, then from the grub prompt (and assuming your boot partition is
the first partition on the disk):
MBR on the first disk:
grub> root (hd0,0)
grub> setup (hd0)
MBR on the second disk:
grub> root (hd1,0)
grub> setup (hd1)
And then you're done:
Grub supports tab completion, so if you put in
grub> root (hd
and hit the tab key, it will show the valid drive numbers. It will do
the same for the partitions if you hit tab after:
grub> root (hd1,
to help you pick the correct partition. Remember, all numbers are
zero-origin, so if the parition holding /boot is /dev/sda1, its
partition number will be 0 in grub.
And, as always, a bootable grub disk as a safety measure is highly
