So I have a Toshiba Satellite laptop that I just tried to fully install Ubuntu 14.10 (I think, most recent) on.
When I originally clicked Try, everything would load as expected.
So I tried to install but when I go to restart laptop with no USB in I get a black screen with a blinking cursor. I read somewhere one possibility may be the grub has installed on the USB Can't boot without Flash Drive plugged in
I try to restart laptop with USB in and select Try, but now when Ubuntu loads I get prompted for a password. This didn't happen before. I put in the password of choice (easy to remember as it is the username) but I get password not recognised error.
Any thoughts or suggestions on what to do next?
