After reading your last post a while ago... I just have to come back to it.
Please don't be offended as this is purely friendly advise. If this just happens to be your first Linux, you really should consider keeping Windows until you are completely comfortable with Linux. Whether it's on another partition, or another computer. You need some sort of "lifeline" to the internet, and any information you can get to fix your Linux install if something goes wrong. And it can.
So if you're going to wipe Windows off of that computer. Please make sure you have a fall back. Just in case.
