@lnusama Ohohoh yeah...
Windows upgrades are notoriously BAD. And while I had no issues upgrading mine, I had to reinstall a few other PCs for friends.
My take :
Backup EVERYTING you can including AppData stuff. All you don't wanna lose.
Prepare a Windows ISO
Fresh CLEAN install from 0
@lnusama Without looking more into the errors I can't say much. But that would be my initial guess. If you go from error to error constantly without the changing of components fixing it, that means that the system is likely stuck with corrupted data, fucked settings and old stuff
@lnusama At this point the issue might just be the system itself. If the OS have been installed for long (and mostly if it's windows, this incredible fuckin bitch....) it can keep the settings of older components that just don't go well with newer ones. Ask me how I know..
