Windows 10 in Off Topic Posted February 11, 2016 Do you know if there's a way to perform a clean install of windows 10 onto a new hard disk drive ? My hard disk drive is really old and I have bought a new one. I upgraded from windows 7 OEM to windows 10 home edition last july. I think there are 3 possibilities : _ either I clone windows 10 from old hdd to new hdd (with all possible errors that came with the upgrade of my old windows 7 to windows 10) or I install windows 7 with my W7 license key and then I upgrade to 10... time consumming Or (which would be great) there's a way to install a clean windows 10 onto my new hard disk drive : using which key ? will I get some issue with activation ?
