It's a lot of work and not without risk, but there is no way that I know of to get past those failed upgrades. Print out the report and you should be able to activate your W10 installation with the OEM W8.1 product key in from the Showkey Plus report by changing the product key in the PC settings menu. Now You can Activate Windows 10 Using Windows 7, 8 or 8.1 Product Key – AskVGĪfter you get W10 installed (or you can do it now), install the free Showkey Plus utility from the Microsoft Store.

You can delete every partition on the hard drive since the recovery partition will no longer work after you clean install Windows.

Select the 'I don't have a product key' option. Then you will be asked to enter a product key. You can make a bootable W10 installation flash drive with the Media creation tool from the link below.īoot from the installation media and after you get past the Install Now screen, you will be asked to select the version of W10 you want to install.
