I tried using the tool from the microsoft site but after 30 minutes or so it always says windows 10 didn't install.I have an AMD A8-6600K processor which appears on the microsoft list as ok.Windows 11 however is not compatible with my cpu.I bought a cheap licence last year which I hope still works (although I understand that they can be hacked over time)? I have an SSD and a HDD on the pc and tried with both.
