The fdisk /mbr command only re-writes the MBR on the system drive (DISK-0) using BIOS calls. You cannot specify any other drive for the fdisk /mbr command to operate on other than DISK-0

:
Deleting and formatting partitions will not affect any boot loaders. Just installing XP from the CD (or any windoze version) will overwrite your boot loader for you (with no warning....thanx Bill!). You can delete it by hand from within linux with:
# dd if=/dev/zero of=/dev/hda bs=512 count=1
You can do the same but keep the partition table intact with:
# dd if=/dev/zero of=/dev/hda bs=446 count=1
