PC troubles

My pc is giving me more troubles than I thought. Last week it turned out I had a virus on my pc.
Sunday evening I re-installed Windows Vista on my pc, everything went well. But yesterday I couldn't start my computer, he gave me a few errors and I had to do this and that and blablabla. So after a while I finally got it working and I thought, I'm not working with Windows again!
So I downloaded Ubuntu, burned it on a cd an started my pc. I have to say that it looks better then Windows.

But I'm not ready no tonight I'm going to make a dual-boot, Windows and Ubuntu, so we can make a choice when we start te computer.

Wish me luck!
