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

Windows 11 includes a useful tool called Startup Repair that helps fix problems preventing your PC from booting properly. However, sometimes this tool itself may fail to work, leaving you stuck on a repair loop or error message. This can be frustrating but don’t worry — there are several ways to resolve this issue.

In this article, we will guide you through simple, step-by-step solutions to fix the Startup Repair not working error on Windows 11. Each method is explained in basic terms so anyone can follow along easily.

By trying these solutions in order, you can identify and fix the root cause of the problem. Let’s get started.

Remember, patience and careful execution are key when troubleshooting startup issues.

Quick Note: Prerequisites and Initial Checks

  • Backup Important Data: If possible, back up your important files before proceeding. Some solutions involve advanced steps that could risk data loss.
  • Check External Devices: Disconnect all unnecessary USB devices, external drives, and peripherals. Sometimes these cause boot conflicts.
  • Ensure Power Supply: Make sure your PC is plugged in and has a stable power source during the repair process.
  • Have Windows 11 Installation Media Ready: A USB or DVD with Windows 11 setup may be required for advanced repair options.

Step 1: Perform a Simple Restart

Before diving into complex fixes, try restarting your PC normally. Sometimes, a simple reboot can clear temporary glitches causing Startup Repair to fail.

  • Press and hold the power button until the PC turns off.
  • Wait about 10 seconds, then press the power button again to start the PC.
  • Check if Windows loads properly or if Startup Repair is triggered again.

Why? Temporary system errors or incomplete updates can often be resolved by a full restart.

Step 2: Boot Into Safe Mode

Safe Mode starts Windows with minimal drivers and services, which helps isolate problems that prevent normal startup.

  • Turn off your PC completely.
  • Turn it back on and repeatedly press the F8 key (or Shift + F8 on some systems) before Windows logo appears.
  • If this doesn’t work, interrupt the boot process three times by turning off the PC during startup to trigger Automatic Repair.
  • In Automatic Repair screen, select Advanced options > Troubleshoot > Advanced options > Startup Settings > Restart.
  • After restart, press 4 or F4 to enter Safe Mode.

Once in Safe Mode, try to identify if any recently installed software or drivers are causing the problem. You can uninstall suspicious items or run antivirus scans.

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

Corrupted system files can prevent Startup Repair from working. Running built-in tools like SFC and DISM can scan and fix these files.

  • While in Safe Mode or from the Command Prompt in Advanced options, open Command Prompt as administrator.
  • Type the following command and press Enter:
sfc /scannow

This command scans all protected system files and repairs corrupted ones.

  • After completion, type this command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth

DISM repairs the system image, which can fix deeper issues.

Restart your PC after these scans and check if Startup Repair works.

Step 4: Use Bootrec Commands to Repair Boot Configuration

Sometimes the boot configuration data (BCD) becomes corrupted, causing Startup Repair failure. You can fix this using Bootrec commands.

  • Boot into the Windows Recovery Environment (WinRE) using installation media or Automatic Repair screen.
  • Select Advanced options > Command Prompt.
  • Type the following commands one by one, pressing Enter after each:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands will repair the Master Boot Record (MBR), write a new boot sector, scan for Windows installations, and rebuild the boot configuration data.

After completing these commands, restart your PC and check if the issue is resolved.

Step 5: Disable Automatic Startup Repair

If your PC is stuck in a loop trying Startup Repair repeatedly, disabling it temporarily might help.

  • Access Command Prompt via WinRE.
  • Run the following command:
bcdedit /set {default} recoveryenabled no

This disables automatic startup repair, allowing your PC to boot normally or proceed with other troubleshooting steps.

To re-enable Startup Repair later, use:

bcdedit /set {default} recoveryenabled yes

Step 6: Restore Your System Using System Restore

If Startup Repair still doesn’t work, restoring your PC to an earlier point when it was working can fix the issue.

  • In WinRE, go to Troubleshoot > Advanced options > System Restore.
  • Select a restore point before the problem started.
  • Follow the prompts to complete the restore process.

This method does not affect your personal files but may uninstall recent apps or drivers.

Alternative Advanced Options

If the above steps do not work, you may consider:

  • Resetting Windows 11: This option reinstalls Windows while keeping or removing your personal files.
  • Reinstalling Windows: A clean installation may be necessary if system files are severely damaged.
  • Checking Hardware: Faulty hard drives or RAM can cause startup issues. Running diagnostics or replacing hardware might help.

FAQs

Why does Startup Repair sometimes fail?

Startup Repair can fail due to corrupted system files, damaged boot configuration, hardware issues, or software conflicts preventing the tool from completing repairs.

Can I fix Startup Repair without losing data?

Yes, many repair methods like Safe Mode, SFC, DISM, and System Restore do not delete personal files. However, always back up data when possible.

How do I create Windows 11 installation media?

You can download the official Media Creation Tool from Microsoft’s website and use it to create a bootable USB or DVD.

Is it safe to disable automatic Startup Repair?

Disabling it temporarily can help break repair loops, but it should be re-enabled after troubleshooting to maintain system protection.

What if my PC doesn’t boot at all?

Try accessing the BIOS to check boot order, run hardware diagnostics, or use installation media to access recovery tools.

When Nothing Works

If none of the above solutions fix the Startup Repair not working error, consider the following options:

  • Contact Microsoft Support: Official help can provide specialized assistance.
  • Visit a Professional Technician: Hardware or complex software issues may require expert diagnosis.
  • Use Official Microsoft Forums: Community advice can sometimes offer unique fixes.
  • Consider Data Recovery Services: If data is critical and inaccessible, professional recovery might be necessary.

Conclusion

Startup Repair is a valuable tool, but when it fails on Windows 11, it can be alarming. By following this simple, step-by-step guide, you can troubleshoot common causes like corrupted files, boot configuration errors, and software conflicts.

Start with basic steps like restarting and Safe Mode, then move to running system scans and repairing boot files. If needed, use System Restore or advanced options.

Always remember to back up your data before attempting repairs and don’t hesitate to seek professional help if the problem persists.

With patience and careful action, you can get your Windows 11 PC back up and running smoothly.
