I installed Ubuntu using the Windows Installer (Wubi). When I start my computer and select Ubuntu, my screen goes black and I see a blinking cursor at the top left of the screen. I have waited an hour, but nothing happens. I have tried restarting the computer multiple times, but the same thing always happens. Windows works fine though.
I am trying to use Ubuntu 12.04 LTS.
I also tried to install Ubuntu using a USB drive, but it would hang during the initial start-up. It would print "voltage table 0x50 unknown" and freeze.
Can anyone tell me what I am doing wrong? I need Ubuntu for work.
