How much space would I need on my hard drive if I wanted to do a dual boot?
You can install most linux distros within 5GB, if that is any help.
I'm personally using Kubuntu at the moment and find it great, its basically my first linux experience and I'd like to clear up that linux is not "hard" just different. As long as you have an internet connection and the sense to search Google for your initial problems you will be flying before too long.
Sweet thanks... B) I was going to wait until I got another hard drive to install it but if that's all I need than I can do it now. I have used Ubuntu before I liked it a lot, beryl is fun to play with.
