(Note: there is a bug in current versions of gdisk: attribute 2 is the legacy BIOS bootable attribute, but the author got the bit order wrong and so you have to set "attribute 61". parted doesn't support the legacy BIOS bootable attribute yet.) If you don't want tomodify the contents of the disk then it can still be tested, but I don't have a ready-made test for you. -hpa -- H.
