Hi. I'm David, and I'm happy to help you.
Are you trying to reset your PC using Windows Recovery Environment (WinRE)?
If not, try this way:
- On the login screen, click on the power button.
- While holding the "Shift" key, click "Restart". Your computer will then boot into the WinRE;
- On the Choose an option screen, select "Troubleshoot > Reset this PC", and then follow the on-screen instructions.
If the WinRE also asks for a password, please let me know. I'll guide you through an alternative solution
Feel free to ask back any questions.
