What Is Windows 10 Automatic Repair Loop?
Windows Automatic Repair is a built-in recovery feature included in Windows 8, Windows 10, and newer versions. It automatically starts when Windows detects that the system failed to boot several times correctly.
The purpose of Automatic Repair is to find and fix problems that prevent Windows from starting. It checks important system files, boot settings, drivers, and other startup components.
Normally, this process completes successfully and Windows loads normally. However, when the repair tool cannot identify or fix the underlying problem, Windows may enter an endless repair cycle called the automatic repair loop.
During this problem, your computer may repeatedly restart and display messages like:
- Preparing Automatic Repair
- Diagnosing your PC
- Automatic Repair couldn't repair your PC
- Your PC did not start correctly
The good news is that you usually do not need to reinstall Windows immediately. Several built-in Windows tools can repair startup problems and restore normal operation.
Why Does Windows 10 Get Stuck in Automatic Repair?
The Windows 10 automatic repair loop can happen because of software problems, damaged system files, hardware failures, or incorrect system settings.
Understanding the cause helps you choose the correct repair method.
| Possible Cause | What Happens |
|---|---|
| Corrupted Windows system files | Important Windows files become damaged or missing, preventing normal startup. |
| Failed Windows Update | An interrupted or incomplete update can damage startup files. |
| Damaged Boot Configuration Data (BCD) | Windows cannot find the information needed to start the operating system. |
| Hard drive or SSD errors | Disk problems can prevent Windows from reading important files. |
| Incorrect drivers | A faulty or incompatible driver can cause startup crashes. |
| Windows Registry corruption | Incorrect registry settings can stop Windows from loading. |
| Malware infection | Viruses can modify or damage important startup files. |
Signs of Windows 10 Automatic Repair Loop
You may have an automatic repair loop problem if you notice the following symptoms:
- Windows shows "Preparing Automatic Repair" but never starts.
- The computer remains stuck on "Diagnosing your PC".
- Windows restarts repeatedly before reaching the login screen.
- A blue screen appears with the message "Automatic Repair couldn't repair your PC".
- The screen becomes black after the repair process begins.
If you are experiencing any of these problems, continue with the solutions below.
Things to Try Before Advanced Repairs
Before using advanced Windows recovery tools, try these simple solutions first. Sometimes the problem is caused by temporary hardware issues or connected devices.
1. Disconnect External Devices
Remove all unnecessary devices connected to your computer:
- USB flash drives
- External hard drives
- Printers
- Memory cards
- Other USB accessories
After removing these devices, restart your computer and check whether Windows starts normally.
A damaged USB device or external storage device can sometimes prevent Windows from completing the boot process.
2. Perform a Complete Power Restart
A complete shutdown can clear temporary hardware problems and memory errors.
- Hold the power button for about 10 seconds until the computer turns off.
- Disconnect the power cable if you are using a desktop computer.
- Wait for about 30 seconds.
- Turn the computer on again.
3. Check Recent Changes
Think about what happened before the automatic repair loop started.
- Did you install a new driver?
- Did Windows install a recent update?
- Did you install new software?
- Did you replace hardware?
Recent changes are often the reason behind Windows startup problems. The following repair methods can help undo these changes.
Fix 1: Use System Restore to Undo Recent Changes
System Restore restores important Windows settings and system files without deleting your personal files such as documents, pictures, and videos.
How to Run System Restore from Automatic Repair
- On the Automatic Repair screen, click Advanced Options.
- Select Troubleshoot.
- Open Advanced Options.
- Select System Restore.
- Choose a restore point created before the problem started.
- Click Next and wait for Windows to complete the restore process.
After the restore is completed, restart your computer and check whether Windows can boot normally.
Create System Restore points before installing major drivers or software. This makes it easier to recover from future Windows problems.
Fix 2: Repair Corrupted Windows Files Using SFC Scan
Corrupted or missing Windows system files are one of the most common causes of startup problems. The System File Checker (SFC) tool can scan Windows files and repair damaged components automatically.
How to Run SFC Scan in Windows Recovery Mode
- Open the Automatic Repair screen.
-
Go to:
Troubleshoot → Advanced Options → Command Prompt - Type the following command:
sfc /scannow
Press Enter and wait until the verification process reaches 100%.
If SFC finds damaged files, Windows will attempt to replace them with correct versions.
Common SFC Scan Results
| Message | Meaning |
|---|---|
| Windows Resource Protection did not find any integrity violations | No corrupted system files were found. |
| Windows Resource Protection found corrupt files and successfully repaired them | The problem files were fixed successfully. |
| Windows Resource Protection found corrupt files but was unable to fix some | Run the DISM repair tool and try SFC again. |
Fix 3: Check Hard Drive Errors Using CHKDSK
A damaged hard drive or SSD can cause Windows startup failures. The CHKDSK tool checks your drive for file system errors and bad sectors.
Run CHKDSK Command
Open Command Prompt from Advanced Options and enter:
chkdsk /r c:
Press Enter and allow Windows to scan the drive.
The CHKDSK process can take a long time depending on:
- Drive size
- Number of errors
- Drive speed
Do not turn off your computer while CHKDSK is running. Interrupting the process may cause additional file system problems.
What CHKDSK Repairs
- File system errors
- Damaged file records
- Bad sectors on the drive
- Incorrect disk information
Fix 4: Boot Windows 10 Into Safe Mode
Safe Mode starts Windows with only essential drivers and services. It is useful when a faulty driver, software, or update is causing the automatic repair loop.
After entering Safe Mode, you can remove problematic programs, uninstall drivers, or scan your computer for malware.
How to Enter Safe Mode from Automatic Repair
- Select Advanced Options on the Automatic Repair screen.
-
Choose:
Troubleshoot → Advanced Options -
Click:
Startup Settings -
Click:
Restart -
Press:
4 - Enable Safe Mode
Things You Can Do in Safe Mode
- Uninstall recently installed software.
- Remove faulty device drivers.
- Run antivirus scans.
- Disable problematic startup applications.
- Install Windows updates correctly.
Fix 5: Repair Windows Using DISM Tool
If SFC cannot repair corrupted Windows files, the Windows component store itself may be damaged. The DISM (Deployment Image Servicing and Management) tool can repair the Windows image.
Run DISM Repair Command
Open Command Prompt and type:
DISM /Online /Cleanup-Image /RestoreHealth
Press Enter and wait for the repair process to finish.
After DISM completes, run SFC again:
sfc /scannow
This combination often fixes Windows files that caused the automatic repair loop.
Fix 6: Repair Windows Boot Files Using Bootrec Commands
Windows may fail to start if the boot configuration files are damaged. The Bootrec tool can repair important startup information.
Open Command Prompt
Go to:
Automatic Repair → Advanced Options → Command Prompt
Run the following commands one by one.
Repair Master Boot Record
bootrec /fixmbr
This repairs the Master Boot Record, which contains startup information.
Repair Boot Sector
bootrec /fixboot
This writes a new boot sector to the system partition.
Scan Windows Installations
bootrec /scanos
This searches for Windows installations that are not included in the Boot Configuration Data.
Rebuild Boot Configuration Data
bootrec /rebuildbcd
This rebuilds the Windows boot menu and startup configuration.
If Bootrec commands do not solve the problem, check your SSD/HDD health because hardware failure can create repeated boot repair problems.
Fix 7: Remove Recently Installed Windows Updates
Sometimes a failed or incomplete Windows update can damage startup files and cause the Windows 10 automatic repair loop.
If your computer started showing the repair loop immediately after a Windows update, removing the latest update may solve the problem.
How to Uninstall Windows Updates from Recovery Mode
- Open the Automatic Repair screen.
-
Select:
Advanced Options → Troubleshoot -
Choose:
Advanced Options → Uninstall Updates -
Select:
Uninstall latest quality update - Restart your computer.
If the problem continues, you can also try removing the latest feature update.
Always create a restore point before installing major Windows updates. It allows you to easily return to a working system.
Fix 8: Disable Early Launch Anti-Malware Protection
Windows includes a security feature called Early Launch Anti-Malware Protection. It loads security drivers before other Windows components.
In rare cases, a faulty security driver can prevent Windows from starting and cause an automatic repair loop.
Steps to Disable Early Launch Anti-Malware Protection
- Open: Advanced Options
- Select: Startup Settings
- Click: Restart
- Choose: Disable early launch anti-malware protection
After Windows starts, check whether recently installed security software or drivers need to be updated or removed.
Fix 9: Disable Windows Automatic Repair Loop Using Command Prompt
If Windows repeatedly enters Automatic Repair without fixing the problem, you can temporarily disable automatic recovery.
This allows Windows to attempt a normal startup instead of launching the repair environment every time.
Disable Automatic Repair
Open Command Prompt from Advanced Options and type:
bcdedit /set {default} recoveryenabled No
Press Enter and restart your computer.
Disabling Automatic Repair does not solve the original problem. It only stops the repeated repair process. Use this after trying other repair methods.
Fix 10: Repair Windows Registry Problems
The Windows Registry stores important system settings. If registry files become damaged, Windows may fail to start correctly.
Windows automatically creates registry backups on many systems. If a backup exists, you may be able to restore it using Command Prompt.
Open Command Prompt
Go to:
Automatic Repair → Advanced Options → Command Prompt
Navigate to the Registry folder:
cd C:\Windows\System32\config
Before making changes, create a backup:
mkdir backup
Copy current registry files:
copy *.* backup
If a previous registry backup is available, restore it carefully.
Incorrect registry changes can prevent Windows from starting. Only restore registry files if you understand the process.
Fix 11: Reset Windows 10 Using Reset This PC
This reinstalls Windows system files and can fix severe software problems.
Reset Windows 10 from Recovery Mode
- Open: Troubleshoot
- Select: Reset this PC
- Choose one option:
- Keep my files – removes apps and settings but keeps personal files.
- Remove everything – completely removes files and reinstalls Windows.
For most users, the Keep my files option is the safer choice.
Even when choosing "Keep my files", always back up important data whenever possible.
Fix 12: Perform a Clean Windows 10 Installation
A clean Windows installation is the final solution when system files are severely damaged or recovery tools cannot repair the problem.
Before Reinstalling Windows
- Back up important documents, photos, and personal files.
