I would suggest booting with a "Live CD" such as Ubuntu or Knoppix. Mount the drive with Fedora as say "/mnt/hdb1". I believe Ubuntu will do this automatically. Check that that your /mnt/hdb1/boot/grub/menu.lst is correct. It should end with:
Quote:
# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Windows NT/2000/XP (loader)
root (hd0,0)
savedefault
makeactive
chainloader +1

If this is ok then you should consider re-installing grub. Look at this:
