Getting Your PC to Start Again: Using Startup Repair

Windows startup repair is a built-in tool that fixes common problems stopping your computer from booting properly. It runs inside the Windows Recovery Environment, which is a special repair screen that opens before Windows starts up. If your PC loops on a loading screen or fails to boot, this tool scans for missing system files and fixes them automatically.

Startup Repair runs inside the Windows Recovery Environment (WinRE), a special diagnostic screen that loads before Windows starts. If your computer won’t start, WinRE might open automatically. If it doesn’t, you can access it manually.

Step 1Getting to the Windows Recovery Environment (WinRE)

Opening the Windows Recovery Environment (WinRE) lets you access repair tools when your computer has problems. If your PC still boots to the desktop, you can open WinRE through the Settings app. Open Settings, go to System, click Recovery, and click Restart now next to Advanced startup to reboot your computer straight into the repair menu.

Method 1Getting to WinRE from inside Windows

If your PC still boots to the desktop, open Settings to reach WinRE quickly.

  • Open Settings. You can click the Start button and then the gear icon, or press the Windows key + I on your keyboard.
  • Go to Update & Security. In the Settings window, click on "Update & Security."
  • Choose Recovery. On the left side menu, click on "Recovery."
  • Select Advanced startup. Under "Advanced startup," click the "Restart now" button.

Method 2Getting to WinRE when Windows Won't Start

Startup Repair is most often needed in this situation. If your PC fails to start Windows correctly a few times, Windows will typically try to open the recovery environment on its own. But if it doesn't, or if you want to make it happen, you can do this:

  • Turn on your PC. Wait until you see the Windows logo or your computer maker's logo.
  • Force a shutdown. As soon as you see the logo, press and hold the power button on your PC until it turns off completely. This stops the startup process.
  • Do it again. Turn your PC back on and repeat the process of waiting for the logo and then forcing a shutdown two more times. This means you do it a total of three times.
  • Enter WinRE. The fourth time you turn on your PC, Windows should see that it didn't start correctly and will automatically show "Preparing Automatic Repair," then the Windows Recovery Environment.

Method 3Using Windows Installation Media or a Recovery Drive

When your PC is badly damaged or other methods fail, starting from a Windows installation USB drive or a recovery drive you've made can help.

  • Put in your installation media or recovery drive. Make sure it's plugged into your PC.
  • Restart your PC. You might need to change your computer's settings (BIOS or UEFI) to start from USB first. This usually means pressing a key like F12, F10, ESC, or DEL right after you turn on your computer to open the boot menu.
  • Choose the right starting device. Pick your USB drive or recovery drive from the boot menu.
  • Follow the instructions. When the Windows Setup screen shows up, choose your language, time, and keyboard settings, then click "Next."
  • Go to repair options. On the next screen, look for a link that says "Repair your computer" in the bottom-left corner. Click it.

Step 2Finding Startup Repair

Finding startup repair in the Windows Recovery Environment requires navigating through two main menu screens. Once you see the choose an option screen, click Troubleshoot, select Advanced options, and then click Startup Repair. Your computer will restart and scan for boot problems automatically after you pick this option.

  • Choose Troubleshoot. From the "Choose an option" screen, select "Troubleshoot." This is where all the advanced fixing tools are.
  • Select Advanced options. On the "Troubleshoot" screen, you'll see a list of more specific tools. Click on "Advanced options."
  • Choose Startup Repair. Here you will find "Startup Repair." Select it. This is the tool that will check your computer for startup problems and try to fix them automatically.
  • Choose your operating system. If asked, pick the operating system you want to fix (usually, there will only be one option for your current Windows).
  • Let Startup Repair work. Your computer will restart, and Startup Repair will start its scan. You'll see a progress bar. This can take a few minutes or over an hour, depending on how bad the problems are and how fast your computer is.
