Hi. I'm David, and I'm happy to help you.
Try to repair the Windows startup by following the steps below.
You will need to access the Windows Recovery Environment (WinRE). In your case, to do this, you will repeatedly turn your device off, then on:
- Hold down the power button for 10 seconds to turn off your device; (If the device is ON when starting the procedure)
- Press the power button again to turn on your device;
- On the first sign that Windows has started (for example, some devices display the manufacturer's logo with spinning dots when starting), hold down the power button for 10 seconds to turn off your device;
- Press the power button again to turn on your device;
- When Windows starts, hold down the power button for 10 seconds to turn off your device;
- Press the power button again to turn on your device;
- Allow your device to fully start. You will enter WinRE.
- On the Choose an option screen, select "Troubleshoot > Advanced options > Startup Repair".
