How To Fix Windows 11 Startup Repair Loop?
Method 1: Boot into Safe Mode to Access Windows
The first step in resolving a Windows 11 automatic repair loop is to access Safe Mode, a lightweight version of Windows that loads minimal drivers and services.
Steps to Boot into Safe Mode:
- Turn off your PC completely.
- Press the power button and immediately hold Shift + F8 or interrupt boot 3 times to access the Windows Recovery Environment (WinRE).
- Go to:
Troubleshoot → Advanced options → Startup Settings → Restart - When your system restarts, press 4 or F4 to enter Safe Mode.
Once you’re inside Safe Mode, uninstall recent updates or faulty drivers that might have caused the loop. This step alone often fixes boot loop issues in Windows 11.
Method 2: Repair Windows 11 Using Command Prompt (CMD)
If Safe Mode doesn’t work, the Command Prompt is your next best friend. It allows you to manually repair Windows 11 boot problems.
Run the Following Commands:
| Command | Purpose |
|---|---|
sfc /scannow | Scans and repairs corrupted system files in Windows 11 |
chkdsk C: /f /r | Checks for disk errors and repairs bad sectors |
bootrec /fixmbr | Fixes Master Boot Record (useful for boot issues) |
bootrec /fixboot | Writes a new boot sector (may fix “access denied” errors) |
bootrec /rebuildbcd | Rebuilds Boot Configuration Data (BCD) |
Running these commands one by one helps fix corrupted system files in Windows 11 and restores the boot manager. This can completely stop the Windows 11 automatic repair couldn’t repair your PC error.
Method 3: Disable Automatic Repair in Windows 11
Sometimes, Automatic Repair itself causes the infinite loop. Disabling it can break the cycle and let you troubleshoot manually.
How to Disable Automatic Repair:
- Open Command Prompt from recovery mode.
- Type:
bcdedit /set {default} recoveryenabled No - Press Enter and restart your PC.
This command disables automatic repair in Windows 11, allowing you to see the real underlying error message instead of being stuck in a loop.
Method 4: Perform a System Restore or Reset
If none of the previous methods work, you can try System Restore or a Reset, both available in the Windows Recovery Environment.
Option 1: Use System Restore
- Go to Troubleshoot → Advanced Options → System Restore.
- Choose a restore point before the issue started.
- Follow on-screen instructions to revert changes.
Option 2: Reset Windows 11 (Without Losing Files)
- Choose Troubleshoot → Reset this PC.
- Select Keep my files.
- Windows will reinstall while preserving your personal data.
| Option | What It Does | Best For |
|---|---|---|
| System Restore | Reverts to earlier working state | Update or driver-related boot loops |
| Reset this PC | Reinstalls Windows while keeping data | Severe Windows 11 boot loop errors |
| Clean Install | Wipes everything and installs fresh OS | When all other fixes fail |
These restore options are effective when the Startup repair not working Windows 11 issue persists after multiple attempts.
Method 5: Rebuild Boot Files Using Advanced Command Line
When your PC displays “Automatic Repair couldn’t repair your PC”, it often points to missing boot records. Rebuilding them can solve the Windows 11 blue screen automatic repair loop.
Run these commands:
bootrec /scanos
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
If the /fixboot command returns Access Denied, execute:
bootsect /nt60 SYS
Then rerun the bootrec commands.
This process helps repair Windows 11 boot problems by rewriting core boot information.
Method 6: Check Hardware and BIOS Settings
Sometimes, hardware conflicts or BIOS misconfigurations cause the Windows 11 startup repair stuck in loop problem.
Key BIOS/UEFI Checks:
| Setting | Recommended Configuration | Impact |
|---|---|---|
| Boot Order | Ensure system drive is first | Prevents boot errors |
| SATA Mode | AHCI (not RAID/IDE) | Ensures proper disk access |
| Secure Boot | Temporarily disable | Helps identify driver issues |
| Fast Boot | Disable temporarily | Allows better troubleshooting |
After checking, save changes and restart your computer. This can often fix boot loop issues in Windows 11 without reinstalling.
Method 7: Use Windows 11 Installation Media for Recovery
If your system still won’t boot, you can use a Windows 11 installation USB to perform advanced repairs.
Steps:
- Insert the bootable Windows 11 USB.
- Boot from the USB (change boot order if needed).
- Select Repair your computer → Troubleshoot → Advanced Options.
- From there, you can access Command Prompt, Startup Repair, or System Restore.
This method provides complete access to all Windows 11 repair tools, even if the operating system won’t start at all.
