Boot from CD not working properly
I am trying to install the latest Ubuntu, 12.04 and I am able to boot from the CD just fine. It goes to the screen that says Ubuntu, with the dots below it. When i tried it on another computer, this screen stayed up for a few seconds and then installation proceeded; however, on this computer, this screen remains for over half an hour, and then i get some sort of command-line thing. Help?
I have Windows 7 installed on this computer. When I tried to install with wubi, I got an error saying "permission denied."
