The wubi install was just to get my feet wet, it seems the easiest, quickest and safest option (for someone who is completely new to Linux). Once I'm comfortable, I'll probably give some of the other distros a try.
I've the 12.04 Ubuntu .iso downloaded. Once I've burned to disk does it give an option to repartition during install or do I have to do that myself before hand? The installation guide isn't very clear on how that stuff works.
