Try to access the Windows Recovery Environment, turn your computer on and off three times. While booting, make sure you turn off the computer when you see the loading logo. After the third time, Windows 10 will boot into diagnostics mode. Click Advanced options when the recovery screen appears.
Then in the "Choose an option" screen, click Troubleshoot => Advanced Options =>
Try to use System Restore or Startup Repair options
If that didn't work, then RESET your PC.
in the "Choose an option" screen, click Troubleshoot => Reset this PC and follow the on-screen instructions.
I hope this helps. Feel free to ask back any questions and keep me posted.
