Windows 8 Pro Upgrade but no previous version of Windows installed

I'm considering buying Windows 8 Pro with Upgrade offer. I'm currently using Windows 7.

My question is very simple: Will the installation DVD to be downloaded be able to install Windows 8 from scratch or does it need Windows 7 to be installed?

I'm asking this because I will eventually format my computer and I prefer installing an OS from scratch rather from an existing installation.

You can still use the Clean Install trick from Windows 7 in Windows 8:

  • Install Windows 8 with your key

  • Open regedit.exe with Start Menu Search and navigate to:

    HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/

  • change the value MediaBootInstall from "1" to "0"

  • run slgmr.vbs -rearm and reboot
  • activate Windows 8.

If you are asking if a Windows 8 Pro Upgrade disc can be used to perform a clean install, it is indeed possible and I have done so successfully. You will, however, be required to call in to tech support each time you do so so that they can verify your installation is legitimate.

EDIT: The line you call is not restricted to regular business hours, and is quite convenient, from my experience. It took about 5 minutes last time I called, with about 2 minutes actually speaking to the tech. (11pm EST)

im so confused
