How to fix windows wont start or bootloop

 

If your Windows operating system won't start or is stuck in a boot loop (repeatedly restarting), it can be frustrating, but there are steps you can take to resolve the issue. Here's a guide on how to fix Windows boot problems:

1. Safe Mode:

• Try to boot into Safe Mode. Press the F8 or Shift+F8 key during startup (or another key, depending on your version of Windows) to access the Advanced Boot Options menu. From there, select "Safe Mode." Safe Mode starts Windows with a minimal set of drivers and services and can help you troubleshoot.

2. Last Known Good Configuration:

• If you can access the Advanced Boot Options menu, try selecting "Last Known Good Configuration." This option can revert your system settings to a previous working state.

3. Automatic Repair:

• In Windows 10 and 8, the Automatic Repair feature can help fix boot issues. If Windows detects a startup problem, it should automatically launch this repair process. If not, you can initiate it by booting from a Windows installation media (USB or DVD) and selecting "Repair your computer."

4. System Restore:

• If you've created System Restore points, use the System Restore feature to restore your system to a previous working state. Boot from a Windows installation media or access the Advanced Boot Options menu and choose "System Restore."

5. Check Disk Utility:

• Boot from a Windows installation media or use Command Prompt in Safe Mode to run the Check Disk utility. Run the command chkdsk /f /r to scan and repair disk errors.

6. Repair Boot Configuration:

• Use Command Prompt in the Advanced Boot Options menu or Windows installation media to repair the boot configuration. Run the following commands:

  bash

• bootrec /fixmbr
  bootrec /fixboot
  bootrec /scanos
  bootrec /rebuildbcd
  

7. Use SFC (System File Checker):

• Run the System File Checker tool to check and repair corrupted or missing system files. In Command Prompt, enter sfc /scannow.

8. Startup Repair:

• If Automatic Repair doesn't resolve the issue, you can use a Windows installation media to perform a Startup Repair. Boot from the installation media, select "Repair your computer," and then choose "Startup Repair."

9. Disable Automatic Restart on System Failure:

• If your computer restarts before you can see the error message, you can disable automatic restart. Boot into Safe Mode, right-click "This PC," select "Properties," go to "Advanced system settings," click the "Settings" button under "Startup and Recovery," and uncheck "Automatically restart" under "System failure."

10. Reinstall Windows: - If all else fails and your data is backed up, you may need to reinstall Windows. Boot from a Windows installation media and choose the "Custom" installation option.

Remember that the exact steps can vary based on your Windows version. If you're not comfortable with these steps, consider seeking help from a professional or the manufacturer of your computer. Always back up your important data before attempting any repair or reinstallation of the operating system.
