Against my better judgment, I did an install-in-place when I upgraded from Vista Home Premium to Win7. No excuse, I was just lazy. For sufficient reasons, (see related post a few minutes from now) I now need to do a clean install. What I would like to know is -- What is the protocol for doing a clean install of an upgrade? I know that you can do a clean install from the old OS by starting with the old OS running when you put in the disc. The upgrade can then "see" that this is a legitimate upgrade and you can then proceed from there (even doing a re-format I believe -- and hope). But how about a Re-install? Same procedure?
