The DOS FAT file system was so flaky that two copies of the MBR are
kept. Grub only overwrites the primary copy. I think FDISK /MBR copies
the secondary back over the primary and then you should be back into
normal DOS territory, booting from the first or selected boot partition.
Is it possible that FAT has marked a partition that isn't bootable as
the boot partition? If so set it in DOS FDISK.

The other possibility is that your secondary copy was screwed too. I
think I've seen DOS freeware to create the primary and secondary MBRs.

I have used a version of Winblows that was so stupid it couldn't
overwrite the GRUB MBR but DOS 6 could!

Good luck,
Woo
