Configure GRUB on linux HD MBR.
The way to remove a bootloader is to over-write it with another.
To do this you will have to boot the XP CD, and run "fixmbr" from the recovery centre.
Re-installing grub to the second disk is pretty trivial, but won't help you much until you can sort out the primary disk.
