** Description changed: I have a setup that AIUI is supported, but grub doesn't handle it for some reason. I have 4 3TB disks in a non-UEFI AMD 64-bit PC. Each disk has a 10MiB Bios Boot Partition, and the remainder in a 'linux raid' partition. MDADM then has the 4 linux raid partitions in RAID6. On top of that I have LVM2. Grub-install finds the right modules AFAICT - and I've tried hard coding the gpt+mdadm+lvm recognisers in, wit no joy.
