I now have my Win7 Home Premium upgrade disc. I started to install on my Vista laptop. I want a clean install. I'd really like to format the drive. When I select Custom it has something about saving a windows.old file. I don't want anything that is now on this laptop saved. Anyway I've started with the option to save this file, but I'm not getting the format that I want. Don <www.donwiss.com> (e-mail link at home page bottom).
