You have to map the drive so grub can find it: |
27 |
|
28 |
olympus ~ # cat /boot/grub/device.map |
29 |
(hd0) /dev/sda |
30 |
olympus |
31 |
|
32 |
Also, you can put the boot MBR on any disk - even an old spinner and |
33 |
still have root on the ssd (as above, my ssd is actually /dev/sdd), but |
34 |
the motherboard cant find any (non-usb) boot device unless I create a |
35 |
device.map) - once grub is installed its fine and I think I could delete it. |
