The following makes these assumptions.
a.  XP was installed on /dev/hda, and that fedora is elsewhere.
b.  you used grub to boot XP.
c.  grub is on the MBR.


1.  Boot with Fedora
2.  save the MBR
# dd if=/dev/hda of=/path_to/mbr.img bs=512 count=1
3. reinstall XP
4. boot with knoppix
5. mount the drive where you saved the mbr record
6  restore the saved MBR
# dd if=/moun_path_to/mbr.img of=/dev/hda bs=512 count=1
7. reboot to fedora.

There are of course, other options, such as making a boot floppy, do the 
reinstall of XP, then boot back to fedora from the floppy and doing 
grub-install etc.
