Hey All, I just purchased a new hard drive yesterday, and was looking forward to a clean start with Lion. However, it's now sounding like there isn't a clean install option, and that it simply installs on top of SL. Unfortunately, I don't have my original SL install disk around... I do have a large external that I can time machine to and from. Any ideas or strategies for getting something close to a clean install without having the SL disk?
