    2 Years later, same issue. After installing "Optional Updates" from Windows, somehow broke my system and I got stuck outside of the OS.

    After tons of troubleshooting, this is how I've managed to solve it, even after getting stuck in the loop:

    1. Holding power button during the loading of the "startup repair". Tried that a bunch of times, until one of the attempts, before actually forcefully shutdown, "unfroze" the loading, and made it possible to enter the windows repair screen.
    2. In this screen, I've made the System Restore (it gave an error, so I'm not sure if it was necessary... but the system actually restored successfully despite of the error).
    3. After restarting and getting stuck in the loop again, I've did step 1 again, until got back into the windows repair screen.
    4. Booted into safe mode.
    5. Open CMD as admin, and run sfc /scannow;
    6. After done, in the same window, execute chkdsk /f /r c: 
    7. The system will restart once more, and the issue was fixed.
