How to Fix “Startup Repair Not Working” Error on Windows 11: Step-by-Step Solutions

Windows 11’s Startup Repair feature is designed to fix problems that prevent your PC from booting properly. However, sometimes this tool itself may stop working, leaving users stuck and unsure of what to do next. This article will guide you through simple and effective solutions to get Startup Repair working again.

Each step is explained in a basic way, so even if you’re new to troubleshooting Windows, you can follow along without confusion. We start with easy fixes and gradually move to more advanced options.

Before diving into repairs, it’s important to understand why Startup Repair might fail and how you can safely attempt to fix it without risking your data. Let’s get started.

By following these instructions, you can save time and avoid unnecessary frustration when dealing with Windows 11 boot issues.

Quick Note: Prerequisites and Initial Checks

Before attempting any fixes, ensure the following:

  • Backup Important Data: If possible, back up your important files using an external drive or cloud storage. Some repair steps may risk data loss.
  • Stable Power Supply: Make sure your PC is plugged into a reliable power source to avoid interruptions during repairs.
  • Check for Hardware Issues: Faulty hardware like a failing hard drive can cause Startup Repair to fail. Listen for unusual noises or check your drive’s status in BIOS if you can.
  • Windows 11 Installation Media: It’s helpful to have a USB or DVD with Windows 11 installation files handy for some advanced steps.

Step 1: Restart Your PC and Try Startup Repair Again

Sometimes, a simple restart can fix minor glitches. Turn off your PC completely, wait for about 10 seconds, then power it on again. Windows will usually try Startup Repair automatically if it detects problems.

If Startup Repair does not start or continues to fail, proceed to the next step.

Step 2: Boot into Safe Mode

Safe Mode loads Windows with only essential drivers and services, which can help bypass issues blocking Startup Repair.

  1. Turn off your PC.
  2. Turn it on and as soon as the Windows logo appears, press and hold the power button to force shutdown.
  3. Repeat this process 2-3 times until you see the Automatic Repair screen.
  4. Click Advanced options > Troubleshoot > Advanced options > Startup Settings.
  5. Click Restart.
  6. Once the PC restarts, press 4 or F4 to enter Safe Mode.

Once in Safe Mode, restart your PC normally and see if Startup Repair works. If it still fails, continue to the next step.

Step 3: Run System File Checker (SFC) and DISM Tools

Corrupted system files can cause Startup Repair to fail. Windows includes tools to scan and repair these files.

  1. Boot into Safe Mode (as described in Step 2).
  2. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  3. Type the following command and press Enter:
sfc /scannow

This will scan and repair system files. Wait for it to complete.

  1. Once done, type the following commands one by one, pressing Enter after each:
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

These commands check and repair the Windows image. After completion, restart your PC and try Startup Repair again.

Step 4: Use Command Prompt to Repair Boot Configuration

Sometimes, the boot configuration data (BCD) may be corrupted, preventing Startup Repair from working.

  1. Boot your PC into the Windows Recovery Environment (Automatic Repair screen).
  2. Go to Advanced options > Troubleshoot > Advanced options > Command Prompt.
  3. In the Command Prompt window, type the following commands one by one, pressing Enter after each:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands will attempt to fix the Master Boot Record and rebuild boot configuration data. After running them, restart your PC and check if Startup Repair works.

Step 5: Disable Automatic Startup Repair

If Startup Repair keeps looping or failing, disabling automatic startup repair might help you troubleshoot further.

  1. Access Command Prompt from the Advanced options menu.
  2. Type the following command and press Enter:
bcdedit /set {default} recoveryenabled no

This command disables automatic repair. You can later re-enable it with:

bcdedit /set {default} recoveryenabled yes

After disabling, restart your PC and try booting normally. If you can get into Windows, proceed with further system checks.

Alternative Method: Use System Restore

If Startup Repair is not working, restoring your system to an earlier point can fix the issue if it was caused by recent changes.

  1. From the Advanced options menu, select System Restore.
  2. Choose a restore point dated before the problem began.
  3. Follow the on-screen instructions to complete the restore.

System Restore does not affect your personal files but will remove recent apps and updates.

Frequently Asked Questions (FAQs)

Why does Startup Repair fail on Windows 11?

Startup Repair can fail due to corrupted system files, damaged boot configuration, hardware problems, or malware infections.

Can I fix Startup Repair issues without losing my data?

Yes, many repair methods such as running SFC, DISM, or repairing BCD do not delete personal files. However, backing up data is always recommended before attempting repairs.

What if Safe Mode is not accessible?

If you cannot access Safe Mode, try using Windows 11 installation media to boot and access recovery options.

Is reinstalling Windows the only option if Startup Repair doesn’t work?

Not always. Reinstalling is a last resort after other repair options fail. It usually removes apps and settings but can keep personal files if you choose the upgrade option.

How do I create Windows 11 installation media?

You can download the official Media Creation Tool from Microsoft’s website and follow the instructions to create a bootable USB drive.

When Nothing Works

If none of the above solutions fix the Startup Repair error, consider the following final options:

  • Reset This PC: From the recovery menu, choose Reset this PC to reinstall Windows while optionally keeping your files.
  • Check Hardware: Test your hard drive and RAM using diagnostic tools, or seek professional help if hardware failure is suspected.
  • Contact Microsoft Support: Visit Microsoft Support for official assistance.
  • Reinstall Windows: As a last resort, perform a clean installation of Windows 11 using installation media.

Conclusion

Startup Repair not working on Windows 11 can be frustrating, but most issues can be resolved by following structured steps. Starting with simple restarts and Safe Mode, progressing through system file checks and boot record repairs, you can often restore your PC without losing data.

Remember to back up your files regularly and keep Windows updated to avoid future startup problems. If repairs become too complex, don’t hesitate to seek professional help or use official Microsoft resources to get your system back on track.
