What Causes Windows 11 Not to Start?
There can be several reasons why your Windows 11 fails to boot normally. Here are some of the most common causes:
- Corrupt system files – Critical OS files like bootloader components or registry hives getting corrupted can prevent Windows from starting.
- Driver conflicts – Faulty, outdated or incompatible drivers can cause start-up issues.
- Hardware failure – Defective RAM, storage drives or other hardware components can lead to boot problems.
- Power issues – Improper shutdown, empty CMOS battery etc. can also cause start-up failure.
- Malware infection – Viruses, rootkits or malware that tamper with system files can block Windows from loading.
- Software issues – Recent changes like updates, new installations or configuration changes may sometimes trigger boot problems.
Fix 1: Start Windows 11 in Safe Mode
The first thing to try when Windows 11 won’t boot is starting it in Safe Mode. Safe Mode loads only the essential drivers and services, avoiding any third party conflicts. Follow these steps to boot into Safe Mode:
- Force restart your PC by pressing the power button for 10 seconds.
- On the next boot screen, press and hold the Shift key to bring up the recovery options.
- Select Troubleshoot > Advanced options > Startup Settings > Restart.
- On the Startup Settings screen, press 5 or F5 to boot into Safe Mode.
If Windows starts normally in Safe Mode, it indicates an issue with a third-party driver or software. Use Safe Mode to uninstall recently added drivers, applications or roll back updates.
Fix 2: Restore System to Earlier Point
The System Restore utility rolls back system files and settings to an earlier restore point. Follow these steps to revert to a previous state:
- Boot into Safe Mode using the steps above.
- Open the Start menu, search for Create a restore point and select it.
- In the System Properties window, click System Restore.
- Choose a restore point prior to when the issue started and click Next.
- Confirm the restore and restart your PC.
This will undo recent system changes that may be causing start-up failure.
Fix 3: Run SFC and DISM Scans
Corrupted system files can prevent Windows from loading. Run the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools to scan for and replace corrupt files:
- Type Command Prompt in Start and run it as Administrator.
- To run SFC, enter
sfc /scannow
and press Enter. - For DISM scan, use
DISM /Online /Cleanup-Image /RestoreHealth
. - Restart your PC once the scans complete.
These inbuilt tools will repair damaged system files if any are found.
Fix 4: Fix Boot Issues via Automatic Repair
The Automatic Repair mode in Windows 11 can diagnose and fix common boot problems. Follow these steps:
- On the Windows boot screen, select Advanced options.
- Choose Troubleshoot > Advanced options > Automatic Repair.
- Select your account and enter your password if prompted.
- Automatic Repair will diagnose issues and attempt repairs.
- Once completed, restart your PC.
This automated recovery tool can fix boot issues by rebuilding BCD or repairing EFI boot files.
Fix 5: Refresh or Reset Windows
If system file corruption is extensive, you may have to refresh or reset Windows.
- Refresh reinstalls Windows while retaining your data and settings.
- Reset erases everything and reinstalls Windows from scratch.
Refresh or reset using these steps:
- Boot to Advanced options in the Windows boot menu.
- Go to Troubleshoot > Advanced options > System Restore.

- For faulty drivers, uninstall them and restart Windows to reinstall the correct versions.
Updating faulty drivers or those marked for Windows updates can resolve any conflicts.
Fix 8: Roll Back Recent Changes

- For software updates – Go to Settings > Windows Update and click Uninstall Updates. Target recent problematic updates.
