If you have the XP installation disk and know the admin password you can 
boot from the windows Installation CD and use the console to run fixmbr 
for the MBR and fixboot for the booting.
I admit that I used these tools to restore the MBR when grub is not able 
to recover from a very corrupted MBR.

After you fix the MBR, you should be able to boot Fedora installer or 
rescue CD and reinstall grub to the MBR. I do not think you need to 
reinstall Fedora all from scratch though. That is, unless you like to 
run the installer.

Reviewing the partition table, some of the extended partition is not yet 
assigned from the extended partition. (7153-7283) I do not think that 
the unassigned portion is hurting anything though.
