Hello everyone,
I've recently installed ubuntu 10.10 for the first time on my PC and almost immediately ran into trouble. I'v been running Windows 7 as the main OS and wanted to install ubuntu as a secondary OS to see what it's like.
Every time i boot up my PC and choose to load ubuntu one of the following happens:
1. It loads into "Ubuntu 10.10 ubuntu tty1" and asks me for my username and password.
2. It doesn't load at all, instead giving me an error regarding "missing module" .
3. It loads up as normal without any problems.

I've never seen anything like this before, the first option is the most common. Not knowing what to do, I just reset my computer and then it boots up normally (not all the time though).

I'm new to linux and don't know what the problem might be or where to start. I've searched on several forums for cases like mine, there are people with one of the problems but not both.
Any help would be appreciated.
