Why don't you install grub on the broken system and boot it?
Because rescue mode cannot install grub via grub-install; reported as:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=198064
The mechanism that grub-install uses to identify the "hardware"
is incompatible with the "virtualization" provided by chroot
and rescue mode.
