Windows 10: Windows 10 re-install not working after factory reset to 8.1 with install discs

I re-installed Windows 8.1 on my 2014 HP laptop using the install discs created when I bought the computer. I had been running Windows 10 from the free upgrade for about 4 years. Now the computer will not install Windows 10. It downloads it and tries to install, but I get a dialogue box saying it was not possible to install.Is it worth making a USB boot copy of Windows 10 and installing via the BIOS or is it a problem with the licence?TIA

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
