I downloaded Ubuntu 11.10 one week ago and burned it to a CD. I installed it on my system which has a 1.5 TB hard.

It installed successfully and I clicked on the restart button. The computer restarted and I chose the first option, which was to load Ubuntu. A black screen would appear with a cursor in top left hand side and I think the system was hung. I repeated this process by erasing the last Ubuntu install but I faced a similar problem.

Can anybody help me?
