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