I bought Windows 8 a few years back, worked brilliantly, although I wasn't really fond of it. I later upgraded to Windows 10, which I love! And last week, I bought a SSD, and then things started to go horribly wrong with disk cloning and such. I've still got my Windows 8 install disk laying around somewhere, and I wonder: If I do a clean install fom the Win8 disk, will I be able to upgrade to Win10 again?
