You have to map the drive so grub can find it: olympus ~ # cat /boot/grub/device.map (hd0) /dev/sda olympus Also, you can put the boot MBR on any disk - even an old spinner and still have root on the ssd (as above, my ssd is actually /dev/sdd), but the motherboard cant find any (non-usb) boot device unless I create a device.map) - once grub is installed its fine and I think I could delete it.
