I wanted to upgrade my HDD in my laptop so thought a clean install on Windows would be a good idea too. I completed the install of Windows 8 with no issues. When trying to activate it, it came back with an error message stating that a previous version of Windows could not be found and a clean install wasn't allowed. What I hadn't realised was that I purchase an upgrade version of 8.
I have a purchased copy of Windows 7 that I'm able to install but not sure if I'll be able to activate it because after purchasing 8 I installed (and activated) 7 on another machine.
Can I install Windows 7, not activate it and install 8 with no issues?
