Windows 10 Automatic Repair Loop: 12 Ways to Fix It Without Reinstalling Windows
Is Windows 10 stuck in an Automatic Repair loop? If your PC repeatedly shows messages such as Preparing Automatic Repair, Diagnosing your PC, or Automatic Repair couldn't repair your PC, Windows may be unable to start normally.
You do not always need to reinstall Windows. In many cases, you can repair the startup problem using the recovery tools already included with Windows.
Quick Answer
If Windows 10 is stuck in an Automatic Repair loop, first enter the Windows Recovery Environment and try Startup Repair. If that does not work, try System Restore, uninstall a recent update, start Windows in Safe Mode, and then use tools such as SFC, CHKDSK, DISM, and BCDBoot.
If none of these methods work, you can use Reset this PC or perform a clean Windows installation.

What Is the Windows 10 Automatic Repair Loop?
Windows Automatic Repair is a recovery feature designed to help repair startup problems.
When Windows detects that it cannot start correctly, it may enter the Windows Recovery Environment and attempt to repair the problem automatically.
The problem occurs when Windows cannot complete the repair. The computer may restart and show the same recovery messages again.
This creates an Automatic Repair loop.
Why Does Automatic Repair Keep Running?
Several problems can cause Windows 10 to repeatedly enter Automatic Repair.
- Corrupted or missing Windows system files
- A failed Windows update
- Damaged boot configuration data
- Hard drive or SSD errors
- Incorrect or damaged drivers
- File-system corruption
- Startup configuration problems
- Software changes that prevent Windows from starting
Common Signs of an Automatic Repair Loop
You may be experiencing an Automatic Repair loop if your computer repeatedly displays:
- Preparing Automatic Repair
- Diagnosing your PC
- Attempting repairs
- Automatic Repair couldn't repair your PC
- A blue recovery screen
- A black screen followed by automatic restarting
- Advanced Startup Options after every restart
| What You See | Possible Problem |
|---|---|
| Preparing Automatic Repair repeatedly | Windows cannot complete startup recovery |
| Automatic Repair couldn't repair your PC | Startup files or system files may be damaged |
| Blue screen before recovery | Driver, system, hardware, or update problem |
| Black screen and restart | Startup, driver, display, or hardware issue |
Before You Start the Fixes
Most of the following repairs are performed from the Windows Recovery Environment.
Windows may automatically enter this environment after several failed startups. You can also boot from a Windows installation USB and select Repair your computer.
If possible, disconnect unnecessary USB devices, external drives, printers, and other peripherals before troubleshooting.
Fix 1: Run Startup Repair
Startup Repair should usually be your first repair option because it is specifically designed to fix common Windows startup problems.
- Enter the Windows Recovery Environment.
- Select Troubleshoot.
- Select Advanced options.
- Select Startup Repair.
- Choose your Windows account if requested.
- Enter your password if required.
- Allow Windows to complete the repair.
Restart the computer after the repair finishes.
Fix 2: Use System Restore
If the problem started after installing software, drivers, or making system changes, System Restore may help.
- Open Troubleshoot.
- Select Advanced options.
- Select System Restore.
- Choose your Windows account.
- Select a restore point created before the problem appeared.
- Follow the instructions to complete the restore.
System Restore can return system files, drivers, registry settings, and installed program changes to an earlier state without normally removing your personal files.
Fix 3: Uninstall Recent Windows Updates
A recently installed Windows update can sometimes cause startup problems.
- Open Troubleshoot.
- Select Advanced options.
- Select Uninstall Updates.
- Try uninstalling the latest quality update.
- Restart the computer.
If the problem began immediately after a larger Windows version update, the recovery environment may also offer an option to remove the latest feature update.
Fix 4: Start Windows in Safe Mode
Safe Mode starts Windows with a limited set of drivers and services. This can help determine whether a recently installed driver or program is causing the startup problem.
- Open Troubleshoot.
- Select Advanced options.
- Select Startup Settings.
- Select Restart.
- Press 4 or F4 for Safe Mode.
If Windows starts successfully in Safe Mode, remove recently installed drivers or software that may have caused the problem.
For more detailed instructions, see our guide on how to boot Windows in Safe Mode.
Fix 5: Run System File Checker
Corrupted Windows system files can prevent Windows from starting correctly.
From the Windows Recovery Environment, open Command Prompt.
First, determine the drive letter assigned to your Windows installation. In recovery mode, Windows may not always be installed on C:.
You can check the drives by entering:
diskpart
list volume
exit
Look for the volume containing the Windows folder.
For example, if Windows is installed on C:, run:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
Replace C: with the correct Windows drive letter if necessary.
Fix 6: Check the Drive with CHKDSK
File-system errors or drive problems can also cause Windows startup failures.
From Command Prompt in Windows Recovery Environment, run:
chkdsk C: /f
Replace C: with the correct Windows drive letter.
If you suspect physical drive problems, a deeper scan can take much longer:
chkdsk C: /f /r
/r option can take a long time, especially on large or damaged drives. If the drive is showing signs of physical failure, back up important data as soon as possible and consider replacing the drive.
Fix 7: Run DISM
DISM can repair problems in the Windows component store. When Windows is running normally, the common command is:
DISM /Online /Cleanup-Image /RestoreHealth
However, when you are working from the Windows Recovery Environment, you should not automatically use the /Online option because you are repairing the Windows installation on the disk rather than the currently running recovery environment.
You can first identify the correct Windows drive and then use an offline repair command such as:
DISM /Image:C:\ /Cleanup-Image /RestoreHealth
Replace C: with the actual Windows partition.
Fix 8: Repair Windows Boot Files
Damaged boot configuration data can prevent Windows from starting.
Open Command Prompt from Advanced options.
On some systems, the following Bootrec commands can help:
bootrec /fixmbr
bootrec /scanos
bootrec /rebuildbcd
The /fixboot command can also be useful on some systems, but it may return an Access is denied error on modern UEFI installations.
For modern UEFI systems, BCDBoot is often a better method for recreating the Windows boot files.
First identify the Windows partition and the EFI System Partition. Then, after assigning the EFI partition a drive letter, a command may look like:
bcdboot C:\Windows /s S: /f UEFI
Here, C: represents the Windows partition and S: represents the EFI System Partition. Your drive letters may be different.
Fix 9: Disable Early Launch Anti-Malware Protection
If a security driver is preventing Windows from starting, temporarily disabling Early Launch Anti-Malware Protection may allow Windows to boot.
- Open Troubleshoot.
- Select Advanced options.
- Select Startup Settings.
- Select Restart.
- Choose the option to disable early launch anti-malware protection.
If Windows starts after this change, investigate recently installed security software or drivers.
Fix 10: Temporarily Disable Automatic Recovery
This is mainly a troubleshooting step, not a permanent repair.
From Command Prompt in the Windows Recovery Environment, you can temporarily disable automatic recovery with:
bcdedit /set {default} recoveryenabled No
Restart the computer and see whether Windows can start normally.
If you need to restore automatic recovery later, use:
bcdedit /set {default} recoveryenabled Yes
Fix 11: Reset This PC
If the previous methods do not work, the Windows Recovery Environment provides the option to reset the PC.
- Select Troubleshoot.
- Select Reset this PC.
- Choose Keep my files or Remove everything.
- Follow the instructions on the screen.
Keep my files normally keeps personal files but removes installed applications and resets many settings.
Remove everything removes personal files, applications, and settings.
Fix 12: Perform a Clean Windows Installation
If Windows remains stuck in the Automatic Repair loop after all other recovery methods, a clean installation may be necessary.
A clean installation removes the existing Windows installation and installs Windows again from installation media.
Before doing this:
- Back up important personal files.
- Make sure you have access to required software installers and licenses.
- Check whether your computer supports Windows 11.
- Create Windows installation media using another working computer if necessary.
- Confirm which drive and partitions contain your important data.
