Startup Repair is a tool in Windows 10 that can resolve problems with files that are required to boot the operating system to a working desktop. This functionality can be accessed both from the desktop and from outside of Windows 10. Furthermore, if your Windows 10 installation is corrupted to the point where you no longer have access to the desktop, you can still use this utility to repair it.
1. Run Startup Repair from Settings app
If you can access to your desktop, you can run Startup Repair from the Settings app.
- Open the Settings app (Win+I keyboard shortcut).
- Go to Update & Security.
- Select the Recovery tab.
- Click Restart Now under Advanced Startup.
- Go to Troubleshoot>Advanced Options>Startup Repair.
2. Run Startup Repair from Desktop/lock screen
From any Windows 10 power options menu, you can easily conduct startup repair. This menu is accessible from the Start menu (if you have access to your desktop), as well as the lock screen.
On the computer:
- Open the Start menu.
- Click the power button.
- Hold down the Shift key and click Restart.
- You will restart and see the Troubleshoot boot menu.
- Go to Advanced Options>Startup Repair
3. Run Startup Repair outside Windows 10
When you can’t see much more than the lock screen, you can run Windows 10 Startup Repair from outside of Windows 10. All it takes is a few failed OS startup attempts. When you fail to boot, the Startup Repair should normally kick in, but if it doesn’t, follow these procedures.
- Power your system on.
- Before you see the Windows 10 loading screen, press the power button again to power the system off.
- Repeat this 3-5 times.
- You will see a message saying Windows 10 failed to boot and is now running Startup Repair.
4. Run Startup Repair from an installation disk
Startup Repair is generally activated when your system fails to launch a few times, but it does require Windows 10 to be working in some way. If the trigger still doesn’t work, you’ll need a Windows 10 installation CD.
To build an installation drive, you’ll need access to another working Windows 10 PC.
Once you have the disk, perform Startup Repair by following the procedures below.
- Boot to BIOS and set the first boot device to USB.
- Connect the installation USB to your PC.
- Power the system On and wait for the Windows 10 installation screen to appear.
- Select the Windows 10 edition, language, etc.
- Click Repair your computer to initiate Startup Repair.
Most problems with Windows 10 can be fixed with Startup Repair, but it may fail at some point. In such situation, you’ll have to reinstall Windows 10. If you can get to the desktop, take advantage of the opportunity to back up your files and reinstall Windows 10.
