Operating System: Microsoft Windows 8.1 (64-bit)
I have tried to run the Windows 10 Installer to upgrade my PC from Windows 8 to Windows 10. Every time I get the error that the Windows 10 Installation has failed. I ran the Windows Update Troubleshooter and it reports that something gets fixed every single time. So I thought that maybe I need to run it until there is nothing left to be fixed. That point never came. Then I got the report that the service registration was missing or corrupt and that it wasn't fixed. I don't know what to do to fix it.
I downloaded the installer on the DVD and tried to start BIOS from DVD installer and that didn't work either.
