GRUB can be installed as the boot record on a partition, usually /boot.
Another MBR bootloader, such as one from Redmond, can then be convinced
to boot GRUB by setting the /boot partition as active, often within
restrictions such as being a primary partition within the first 1024
cylinders.  This can be useful when certain non-open-source operating
systems silently overwrite the MBR, but do provide capabilities to
change the active partition.
