My guess, without a more complete description, is that you need to install GRUB on the MBR for the boot disk. If you can boot to rescue mode and get the Fedora installation mounted, you should be able to do # chroot /mnt/sysimage # grub-install /dev/hda [or whatever your boot device may be] If this fails, post again with more information on the hardware and partition setup.
