Yes you...
I am not sure about PC Linux but some of the popular distributions eg Ubuntu, Fedora and others have a real nice feature that partitions the hard drive for you automatically (after you approve it) giving Windows some breathing space and allowing room for the new image to be installed.
It took me a long time to get comfortable (being a non geek) with the new o/s but now I totally prefer it to any of the others I have experienced...
