Previously I stated I performed a clean install on a clean harddrive from bootup. While it worked at that time, it did not this time. I booted up and loaded a Clean install of Windows 7 by unchecking "upgrade" and not entering the CD Key until I decided to activate. This did not work two days ago. Everything booted up just fine but at activation and upon entering the CD-Key at that time it was rejected due to "you cannot perform a clean install with this version of Windows 7" or something to that effect. Either: a. It worked at that time one month ago and Microsoft closed the "hole" b. There was some portion of Windows XP showing on one of my drives. c. I was dreaming I tend to lean toward "a." in this matter.
