You may also initiate the Startup Repair by yourself from the Advanced Options in the Windows Recovery Environment (WinRE).

Fix 4. Disable Automatic Repair

Automatic Repair doesn't always work. It is known to cause troubles like Windows stuck at "Preparing Automatic Repair", Automatic Repair loop, and the one in the discussion, "Scanning and repairing drive" stuck. Therefore, you can disable Automatic Repair to avoid these problems. To get it done, you will need to enter the Windows Recovery Environment or the Windows installation media.

Step 1. Hold down the power button for 10s to shut down the computer.

Step 2. Press the power button to start the computer. Once you see the first sign of Windows has started, e.g. the logo of the manufacturer, hold down the power button for 10s again to turn off the device.

Step 3. Press the power button to start the computer. Once Windows restarts, hold down the power button for 10s to turn off the computer.

Step 6. Enter bcdedit and remember the values of "identifier" and "recoveryenabled" under Windows Boot Loader, Generally, it's "{current}" and "Yes".

Step 7. To disable Automatic Repair, enter bcdedit /set {current} recoveryenabled no. ("{current}" indicates the current OS and change the value to "no" will abort Automatic Repair.)

Step 8. Restart the computer.

Fix 5. Enter Safe Mode and Run CHKDSK

Step 2. Press the power button to start the computer. Once you see the first sign of Windows has started, e.g. the logo of the manufacturer, hold down the power button for 10s again to turn off the device.
