This is all very unclear terminology, as I mentioned elsewhere. This GPT disk contains a BIOS Boot partition? And you used grub-install on that GPT disk? And when you reboot you're absolutely certain it's loading GRUB off the GPT disk? It doesn't make sense that GRUB loads from a GPT disk, and then can't see that GPT disk. That's pretty inexplicable, don't you think? > Because core.img has been built with part_gpt I can't see the partitions > on either MBR disc. It sounds like os-prober isn't finding systems on those MBR partitioned disks, therefore it's not building MBR support into the core.img. This might have to do with an old version of os-prober, or maybe the partitions os-prober is searching are encrypted. > I note that the version (1.99) of grub2 is quite old - this is the version > that ships with the latest version (12.04) of Ubuntu. 12.10 has 2.00-7 listed in the repos. I suspect you can still use it on 12.04. I don't know if os-prober is a separate package, but I'd make sure that too is as up to date as you can make it.
