usb ubuntu

[Jason Dusek]

I made bootable Ubuntu USB drive, and it boots fine. I can start
the installer, but when I do, it immediately looks for the CDROM
drive and bails. How do I change that? I tried dropping to a
shell and mount /dev/sda1, but that fails with a mysterious
'invalid argument'.

I'm new to Ubuntu, but I have a lot of experience with Linux.
I'm trying to put Ubuntu on my OQO O2.
