Since I never got an answer in Networking about what I should do for the connections limit patch for Vista not working I'm going to download Ubuntu.

First, I want to know if you have to burn the image to a disc and install Ubuntu from that. Also do you have to backup Vista or are the premade recovery files ok?

Are there any specific things I should know before I do this so that I don't completely mess anything up and have to reinstall Vista?

One other thing. Whenever I use Ubuntu, will everything I have be compatible and work right with it? I mean, will the drivers and everything be ok since they all have Vista drivers?

Any help would be great. I always get stressed out before I do something like this since I could potentially mess up the computer and I don't feel like spending hours fixing it.
