I installed GRUB2 onto the USB drive.
SGD 1.98xx does not see the drive at all. The light on the USB drive does not
even flicker.
When I use SGD 0.97xx to "boot directly", it boots to the laptop drive.
Using "Easy swap" does not make a difference. ("Easy swap" assigns the
laptop to hd1 and the USB to hd0. "Boot directly" then boots to hd1.)
I tried removing the laptop hard drive in the hope that it would make it
easier for SGD to find the drive. Both versions of SGD behaved the same as
before.
