...that generally speaking, performing a clean install of Windows 8 is similar to Windows 7, but showing and explaining all the steps is still very useful because it is a new operating system. I wouldn't say there's "Nothing new..."
In the case of this type of upgrade deal, you end up with a standard Windows 8 Pro DVD. The upgrade is verified during the download not during the install. If you look back over the screen shots, nowhere does the installation procedure look to verify a previous installation of Windows 7 on the hard disk.
As such, I was able to do a clean install using the DVD that I created. Furthermore, I see no reason why, in the case of a hard disk failure, I would not be able to use this same DVD to reinstall Windows 8 to a new hard disk in the future.
