When Windows 11 cannot start normally, you may see problems such as a black screen, repeated restarts, an automatic repair loop, or an error message during startup. In many cases, the problem is related to damaged system files, boot configuration problems, or changes that prevent Windows from loading correctly.
Windows 11 includes a built-in recovery tool called Startup Repair that can automatically diagnose and fix certain problems preventing the operating system from starting. You do not need to reinstall Windows to use it, and it is designed to repair startup-related issues while keeping your personal files intact.
There are several ways to access Startup Repair. If Windows can still reach the recovery environment, you can launch it from Settings or the Advanced Startup menu. If Windows cannot boot normally, you can also use Windows installation media to reach the same recovery tools.
In this guide, you will learn different ways to run Startup Repair in Windows 11 and what to do if the automatic repair process cannot solve the problem.
Method 1: Run Startup Repair From Windows 11 Settings
If you can still sign in to Windows 11, the easiest way to access Startup Repair is through the Recovery settings.
- Press Windows + I to open Settings.
- Click System.
- Scroll down and select Recovery.
- Find Recovery options.
- Locate Advanced startup.
- Click Restart now.
- Windows will restart and display the recovery environment.
- Select Troubleshoot.
- Click Advanced options.
- Select Startup Repair.
- Choose your Windows 11 account if prompted.
- Enter your account password if required.
- Allow Windows to diagnose the startup problem.
Windows will examine the system and attempt to repair problems that prevent it from starting correctly.
The computer may restart automatically during the process. Do not turn off the PC while Startup Repair is working.
When the repair finishes, Windows should attempt to boot normally. If the problem was caused by an issue that Startup Repair can resolve, you should be able to sign in again.
Method 2: Open Startup Repair From the Automatic Repair Screen
If Windows 11 fails to start several times, it may automatically enter the Windows Recovery Environment.
You may see a message such as Preparing Automatic Repair or Diagnosing your PC before the recovery options appear.
Once the recovery screen appears:
- Select Advanced options.
- Click Troubleshoot.
- Select Advanced options.
- Click Startup Repair.
- Select your Windows account.
- Enter your password if requested.
- Wait while Windows checks the startup configuration.
Windows will attempt to identify problems that are preventing normal startup.
This method is particularly useful when you cannot reach the Windows desktop and therefore cannot access the Recovery page in Settings.
If Startup Repair successfully fixes the problem, Windows will restart and attempt to boot normally.
If you return to the same recovery screen after restarting, the underlying problem may require another recovery method.
Method 3: Access Startup Repair Through Advanced Startup
You can manually enter Advanced Startup from the Windows 11 Start menu.
This provides another convenient way to reach Startup Repair when Windows is functioning but you want to troubleshoot a startup problem.
- Open the Start menu.
- Click the Power button.
- Press and hold the Shift key.
- While holding Shift, click Restart.
- Continue holding Shift until Windows begins restarting.
- Wait for the recovery options to appear.
- Select Troubleshoot.
- Click Advanced options.
- Select Startup Repair.
- Choose your account if prompted.
- Enter your password if required.
Windows will then begin the startup repair process.
This method is useful because you can deliberately enter the recovery environment without changing BIOS or UEFI settings.
If Windows is currently working but you suspect that a recent change has affected startup, you can use this method to access additional recovery tools as well.
Method 4: Use Windows 11 Installation Media
If your computer cannot reach the normal Windows recovery environment, you can use a Windows 11 installation USB drive to access the recovery tools.
You need a bootable Windows 11 USB drive for this method.
- Connect the Windows 11 installation USB drive to the computer.
- Turn on or restart the PC.
- Open the computer’s boot menu.
- Select the Windows installation USB drive.
- Wait for Windows Setup to appear.
- Select your language and other setup preferences if requested.
- Click Next.
- Do not select Install now.
- Look for Repair your computer.
- Click Repair your computer.
- Select Troubleshoot.
- Click Advanced options.
- Select Startup Repair.
- Choose the Windows installation you want to repair if prompted.
Windows will scan the installation and attempt to correct startup-related problems.
This method is particularly helpful when the internal recovery environment is unavailable or damaged.
Be careful when using Windows installation media. Selecting Install now starts the Windows installation process, whereas Repair your computer takes you to the recovery tools.
Method 5: Run Startup Repair From Command Prompt
If Startup Repair does not automatically fix the problem, Command Prompt in the Windows Recovery Environment provides additional troubleshooting options.
First, open the recovery environment:
- Start the computer and enter Windows Recovery Environment.
- Select Troubleshoot.
- Click Advanced options.
- Select Command Prompt.
You can then use commands to inspect or repair parts of the Windows installation.
For example, you can check the disk for file-system problems with:
chkdsk C: /fYou can also use System File Checker from the recovery environment, although the Windows installation drive may have a different drive letter than C:.
A common offline SFC command is:
sfc /scannow /offbootdir=C:\ /offwindir=C:\WindowsThe correct drive letter should be confirmed before running an offline repair command because the Windows partition may not be assigned C: inside the recovery environment.
You can use DiskPart to inspect available volumes:
diskpart
list volume
exitLook for the volume containing the Windows directory and use its assigned drive letter for subsequent commands.
Command Prompt provides more control than the graphical Startup Repair tool, but commands should be used carefully. Incorrect commands can cause additional problems.
Method 6: Disconnect Recently Added Hardware
Sometimes startup problems are caused by a newly connected device rather than Windows itself.
Before performing more complicated repairs, disconnect unnecessary external hardware.
- Shut down the computer.
- Disconnect USB storage devices.
- Disconnect external hard drives.
- Remove unnecessary USB accessories.
- Disconnect docking stations if applicable.
- Remove recently connected peripherals.
- Leave the keyboard, mouse, monitor, and essential hardware connected.
- Start the computer again.
If Windows starts normally afterward, reconnect the devices one at a time.
This can help identify whether a particular USB device or peripheral is interfering with startup.
Do not disconnect internal components unless you are comfortable working with computer hardware. For most startup problems, testing external devices is enough.
Method 7: Try System Restore After Startup Repair Fails
Startup Repair focuses specifically on problems that prevent Windows from starting. If the issue was caused by a recent software installation, driver update, configuration change, or system modification, System Restore may be more appropriate.
You can access System Restore from the same recovery environment.
- Open Advanced options.
- Select System Restore.
- Choose your Windows account.
- Enter your password if requested.
- Select an available restore point.
- Review the changes that will be made.
- Confirm the restore operation.
- Wait for Windows to complete the process.
System Restore can return certain system files, drivers, settings, and installed software changes to an earlier state.
Your personal documents are generally not the target of System Restore, but applications or drivers installed after the selected restore point may be affected.
If you do not have any available restore points, this option may not be usable.
What to Do If Startup Repair Cannot Repair Your PC
Sometimes Startup Repair displays a message indicating that it could not repair the computer.
This does not necessarily mean that Windows must be reinstalled.
First, restart the computer and check whether Windows can now boot. If it still cannot start, return to Advanced options and try another recovery tool.
Depending on the cause, you can try:
- System Restore to undo recent system changes.
- Uninstall Updates if the problem started after a Windows update.
- Safe Mode to troubleshoot drivers and applications.
- Command Prompt for manual disk and system-file repairs.
- Reset this PC as a last resort when other recovery methods fail.
If you use Reset this PC, carefully review the available options because resetting Windows is a much more significant operation than Startup Repair.
You should also consider whether the problem could be caused by failing storage hardware. If the SSD or hard drive is physically failing, software-based startup repairs may only provide temporary results or fail completely.
Conclusion
Startup Repair is one of the first recovery tools you should try when Windows 11 cannot start normally. It can automatically diagnose and repair certain problems involving startup files, system configuration, and other boot-related issues.
You can access Startup Repair through Settings, the Windows Recovery Environment, Advanced Startup, or Windows 11 installation media. If the automatic tool cannot solve the problem, additional recovery options such as System Restore, Safe Mode, Command Prompt, and update removal can help identify the underlying cause.
Before using more advanced recovery options, disconnect unnecessary external devices and avoid reinstalling Windows unless other recovery methods have failed. If the problem continues after software repairs, check the health of your storage device and consider professional assistance if necessary.
