Do an "ls" from the grub prompt ... when booted from the usb stick grub |
32 |
will renumber the devices in a different order. You will need to use |
33 |
"ls" to find out what the current grub order is, edit the grub menu |
34 |
(i.e., "e" when at the menu selection) and press F10 (I think) when done |
35 |
to boot. The reason is grub will set itself up with the usbstick as |
36 |
root, whereas once you boot with the correct mapping you can reissue the |
37 |
commands to write them properly. |
