Please don't try this unless others reply to support this, but...

If you can boot to a Fedora CD/DVD which is able to detect your Fedora
install then I think it should be something like this...

chroot /mnt/sysimage

fdisk /dev/sda
 Command (m for help): a
 Partition number ([snip] default x): 5
 Command (m for help): w
 The partition table has been altered.
 Calling ioctl() to re-read partition table.

grub2-install /dev/sda
