You could try findgrub
http://www.unixversal.com/linux/openSUSE/findgrub-4.4.1.tgz and/or
bootinfoscript
(https://github.com/arvidjaar/bootinfoscript/blob/master/bootinfoscript
- I point to my repo because SF variant did not work with GRUB2 we
  have here on openSUSE). Both scripts scan disks for bootloaders.
