Windows Blue Screen (BSOD) and Boot Repair¶

A Windows Blue Screen of Death (BSOD) or automatic bootloop indicates a critical system kernel fault, corrupt device driver, hardware incompatibility, or corrupted system file. Structured diagnostic steps restore Windows stability.

Step 1: Accessing Windows Advanced Startup (WinRE)¶

If Windows fails to boot three consecutive times, Windows Environment (WinRE) triggers automatically: 1. Turn off your PC completely by holding the power button for 5 seconds. 2. Turn on the PC and hold the power button for 5 seconds as soon as the Windows logo appears to force a shutdown. Repeat this process 3 times. 3. On the third restart, Windows will display the Preparing Automatic Repair screen, followed by Advanced Options.

Step 2: Running Automatic Startup Repair¶

1. From the Choose an option screen, select Troubleshoot > Advanced Options.
2. Select Startup Repair. Windows will scan system boot configuration data (BCD) and registry hives to fix boot errors automatically.

Step 3: Booting into Safe Mode to Remove Faulty Drivers¶

1. Navigate to Troubleshoot > Advanced Options > Startup Settings > Restart.
2. Upon reboot, press 4 or F4 on your keyboard to enable Safe Mode.
3. In Safe Mode, open Device Manager to roll back recently updated graphics or network drivers, or open Settings > Apps to uninstall newly installed software.

Step 4: System File Repair via Command Prompt¶

1. In Advanced Options, select Command Prompt.
2. Type sfc /scannow and press Enter to scan and repair corrupted system binaries.
3. Type dism /online /cleanup-image /restorehealth and press Enter to repair the Windows component store image.
4. Type chkdsk C: /f /r to fix hard drive bad sectors and filesystem errors.
