It's been 2+ decades of folk telling you to backup what you can't lose. You need to restore your PC from your last backup or factory reset.
I turned off my computer when it was installing Windows 10. I wanted to restart/refresh my PC to clean it. This process took a while, and when I finally thought it was done, it started installing Windows 10. That's the part when I turned it off. Now every time I turn my computer on, it says, "The computer restarted unexpectedly or encountered and unexpected error. Windows installation cannot proceed. To install Windows, click "OK" to restart the computer, and then restart the installation." It goes throw a cycle. Help!
