Hi, I installed Ubuntu 12.04.01 on my zen-book prime UX31A-DB51,
from a USB hard-drive, the installation seems to be fine, but now if I unplug the USB hard-drive everything cruse, and also I can't load the system without the USB hard-drive plugged in.
Did I install part of the system on the USB hard-drive by mistake?
(I can't see any new file on it.)
How can I fix this so I can run without the USB hard-drive plugged in?
thanks for the help.
