Windows Error Recovery

Windows failed to start. A recent hardware or software change might be the cause.

If Windows files have been damaged or configured incorrectly, Startup Repair can help diagnose and fix the problem. If power was interrupted during startup, choose Start Windows Normally.
(Use the arrow keys to highlight your choice.)

Launch Startup Repair (recommended)
Start Windows Normally

Description: Fix problems that are preventing Windows from starting

Startup Repair will fail to load, launch but fail to repair, or run and claim repairs have been executed. Your PC will continue to attempt to endlessly start Startup Repair each boot. In Windows 8, Windows 8.1 and Windows 10 this is called Automatic Repair:

2 - Startup Repair Error Symptoms

Unexpected PC shutdown, virus, malware, driver issues, damaged BDC settings, corrupted boot partition, blue screen of death as well as a black screen of death on reboot, all those factors account for Windows startup problems. 

As the 'Windows error recovery' suggests, Start Repair should automatically fix the abnormal Windows startup. However, when you choose the recommended option, you'll only confront 2 facts:

1. Startup Repair takes a reasonably long time to load or launch.

2. Startup Repair immediately runs, but the repairing process never finishes.

In both situations, on each reboot, your PC will continuously attempt to call Startup Repair for the fix, meanwhile getting stuck in a Startup Repair loop that never ends

Step 1. In Command Prompt, type bcdedit and press "enter".

bcdedit /set {default} device partition=c:
bcdedit /set {default} osdevice partition=c:

After that, reboot the PC and fix the Windows startup repair loop.
