The idea of the Linux tutorials is to give people starting out with Linux a heads up on some of the basics. There nothing like installing a new Operating System on your PC and not knowing where to look for guidance. What I will say about this is before you install Linux you need to sure all your hardware is supported or you might find yourself getting cheesed off with it and going back to Microsoft. So it is really important that you do your homework beforehand.
So make a list of all your hardware then research it before going any further.
