I am looking to install ubuntu primarily because I often muck around with my windows system files (authui.dll & ExplorerFrame.dll being the main two) and read that if I happen to corrupt these dll's really badly and can't access them to fix/replace them from the windows OS I can access them from the ubuntu OS. First up is this true? and if it is, should I install ubuntu using the windows installer or via the CD/USB drive method?
I was reading about the differences between these two options and for the windows installer method one difference stated was that "If your Windows install goes pear-shaped, you may lose access to your Wubi install, too." so from this I'm lead to think that in my case it would pointless to have ubuntu there if I install it through the windows installer, so I should choose the CD/USB option. Some clarification on the issue would be much appreciated. Thanks :)
P.S. I'm a really inexperienced user (have never installed ubuntu before or used a dual boot system) so I'm really sorry if the question I asked seems stupid.
