How do you know that this is the case?
Grub can show you its view of the world if you just ask it to.
First, reboot your computer, then, when the grub menu appears, do
the following,
type: the ESC key - puts you into grub interactive command mode
type: root (hd<TAB> - that means ... lettter h, letter d, then TAB key
Okay, here is an example from the grub shell (running under linux,
where kernel & rootfs is on /dev/hda7 on my computer), but you
need to do this from the *real* grub bootloader on your computer,
grub> root (hd<TAB>
Possible disks are: hd0 hd1 hd2
grub> root (hd0,<TAB>
Possible partitions are:
Partition num: 0, Filesystem type is fat, partition type 0x6
Partition num: 2, [BSD sub-partitions immediately follow]
BSD Partition num: 'a', Filesystem type is ffs, partition type 0xa9
BSD Partition num: 'b', Filesystem type unknown, partition type 0xa9
BSD Partition num: 'e', Filesystem type is fat, partition type 0xa9
BSD Partition num: 'f', Filesystem type is ext2fs, partition type 0xa9
BSD Partition num: 'g', Filesystem type unknown, partition type 0xa9

BSD Partition num: 'j', Filesystem type is ext2fs, partition type 0xa9
BSD Partition num: 'k', Filesystem type is ext2fs, partition type 0xa9
Partition num: 3, Filesystem type is ext2fs, partition type 0x83
Partition num: 4, Filesystem type unknown, partition type 0x82
Partition num: 5, Filesystem type is ext2fs, partition type 0x83
Partition num: 6, Filesystem type is ext2fs, partition type 0x83
Partition num: 7, Filesystem type is ext2fs, partition type 0x83
Partition num: 8, Filesystem type is ext2fs, partition type 0x83
grub> root (hd0,6)<ENTER>

The TAB key is your friend, so is the "find" and "geometry" commands.

Have you read the grub info docs yet?
