Preparing Automatic Repair | Fix Windows Repair Loop

Guide / By

The preparing automatic repair screen appears when Windows fails to start, and you break the loop by repairing files and boot settings.

When your PC suddenly restarts and shows a black or blue screen with a repair message, it feels scary. Windows 10 and 11 trigger this repair mode when startup fails several times in a row. In many cases, the repair screen flashes by once, the fix works, and you boot back to the desktop. The real headache starts when the repair message keeps returning and the system never loads.

This guide walks you through what the repair screen means, what you should try first, and step-by-step fixes that work on both Windows 10 and 11. The goal is simple: get you out of the loop with your files safe and your PC booting again.

What Preparing Automatic Repair Actually Means

Windows includes a built-in startup repair tool that runs when the system fails to boot a few times in a row. On Windows 10 and 11, this tool checks core boot files, startup settings, and some hardware-related areas. When it triggers, you usually see a short message, a spinning circle, and then either a blue screen with recovery options or another restart.

In a normal case, the repair process finishes, fixes a small glitch, and you never think about it again. A one-time repair after a power cut or a driver crash is not a reason to worry. The problem shows up when the repair engine fails, restarts, and calls itself again, creating the loop many users complain about.

Common triggers include corrupted system files, interrupted updates, driver changes, or drive errors. A failing SSD or HDD, bad sectors, or a loose cable can also cause repeat failures. When Windows cannot load key startup components, it keeps trying to repair itself and never reaches the desktop.

On modern systems, this repair mode sits inside the Windows Recovery Environment (WinRE). Reaching WinRE gives you tools such as Startup Repair, System Restore, Command Prompt, and Reset this PC. The fixes in this article revolve around reaching that environment and using those tools in a safe order.

Quick Checks Before You Go Deep

Before you run long commands or reinstall anything, run through a few basic checks. These quick steps often break the loop when the cause is minor, like a bad shutdown or a loose cable.

  • Let the first repair run — If this is the first time you see the message, allow Windows to finish one repair attempt without forcing a shutdown.
  • Remove external devices — Unplug USB drives, external hard disks, printers, and other accessories, then restart to see if the system boots without them.
  • Check power and cables — On desktops, reseat the power cable, data cables for the system drive, and the RAM sticks; then turn the PC back on.
  • Use a full power cycle — Hold the power button until the PC shuts down, unplug power (and battery on older laptops), wait 30 seconds, then plug back in and try to boot.
  • Listen and watch for drive issues — Clicks, grinding sounds, or long pauses at the logo can point to a failing drive that needs quick backup before more tests.

If the system still drops back to the repair screen after these checks, treat it as a startup failure that needs structured repair from WinRE.

Fixing The Preparing Automatic Repair Loop On Windows 10 And 11

Breaking the loop starts with reaching the Windows Recovery Environment reliably. Once you are there, you can run Startup Repair and other tools without the PC instantly restarting.

  1. Force WinRE With Repeated Power Interrupts — Turn the PC on, wait until you see the Windows logo, then hold the power button to shut it down. Repeat this two or three times. On the next boot, Windows should offer Automatic Repair or Advanced options.
  2. Reach Advanced Options — When you see a repair screen, choose Advanced options > Troubleshoot > Advanced options. This menu is the hub for most fixes.
  3. Run Startup Repair Once — From Advanced options, pick Startup Repair and select your Windows account. Let the tool scan and attempt a fix, then check whether the system boots properly.
  4. Try Safe Mode Boot — If Startup Repair fails, return to Advanced options, choose Startup Settings > Restart, then press 4 (or F4) to boot in Safe Mode. If Safe Mode works, you can remove drivers or apps that caused trouble.
  5. Remove Recent Drivers Or Apps — Inside Safe Mode, open Settings > Apps to uninstall recent tools, or use Device Manager to roll back a display, storage, or antivirus driver installed just before the loop began.

Safely reaching Safe Mode or the desktop is a good sign. It usually means the core Windows files still exist and the problem lies in drivers, updates, or settings. If you cannot reach Safe Mode at all, move on to deeper repairs from the recovery menu.

Common Startup Messages And First Steps

Different screens give small hints about what went wrong. This quick table ties common messages to the first action that usually helps.

Startup Message Likely Cause Good First Step
Automatic Repair couldn’t repair your PC System files or boot data still damaged Run Startup Repair once, then use System Restore or command tools
Diagnosing your PC then reboot loop Repeated startup failure, possible drive or driver issue Enter WinRE with power interrupts, try Safe Mode and drive checks
Black screen after logo, no error text Display or graphics driver problem, rare firmware issue Boot into Safe Mode with networking and roll back graphics drivers

These hints do not replace deeper checks, but they steer you toward the right tool so you do not waste time on random changes.

Repairing System Files And The Boot Loader

When Startup Repair fails or the loop keeps returning, the next step is to fix system files and boot data by hand. You will use the Command Prompt inside WinRE for this part. The commands here are standard Microsoft repair steps widely recommended by Windows help articles and support threads.

Run Check Disk On The Windows Drive

  1. Open Command Prompt In WinRE — From Advanced options, select Command Prompt. Pick your account and enter the password if asked.
  2. Find The System Drive Letter — In WinRE, Windows may not live on C:. Type dir c:, press Enter, and check for the Windows folder. If it is not there, try dir d: or other letters until you see that folder.
  3. Run A Disk Check — Once you find the right drive, type chkdsk C: /f /r (replace C: with the correct letter) and press Enter. Confirm when it asks to schedule or start the check. This scan locates bad sectors and fixes file system errors.

The full disk scan can take a long time on older drives, especially with the /r flag. Let it finish. If it reports lots of bad sectors, plan a backup and drive replacement as soon as the system boots again.

Repair Core Windows Files With SFC And DISM

  1. Mount The Windows Image If Needed — In most WinRE setups, you can work directly against the installed Windows copy. Keep using the same drive letter you found earlier.
  2. Run System File Checker — In Command Prompt, type sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows (adjust letters if needed) and press Enter. This tool checks core system files and replaces damaged copies with cached ones.
  3. Use DISM For Deeper Image Repair — If SFC reports problems it cannot fix, run DISM /Image:C:\ /Cleanup-Image /RestoreHealth with the right drive letter. This command repairs the underlying Windows image that SFC relies on.

When these scans finish without errors, restart from the recovery menu and see whether the PC can boot. If it still falls back into a repair loop, boot data itself might be damaged.

Rebuild Boot Configuration Data (BCD)

  1. Stay In Command Prompt — Keep the same WinRE command window open on the correct system drive.
  2. Back Up Old Boot Data — Run bootrec /scanos to scan for Windows installs, then bootrec /fixmbr and bootrec /fixboot to refresh the master boot record and boot sector.
  3. Rebuild The BCD Store — Run bootrec /rebuildbcd. When asked to add detected Windows installs to the boot list, type Y and press Enter.
  4. Restart And Test — Close Command Prompt, return to the main menu, and choose Continue to boot Windows. Watch to see whether the repair loop finally stops.

On UEFI systems with secure boot, some commands might behave slightly differently, but the general pattern of scanning, fixing, and rebuilding boot data stays the same.

When Windows Still Will Not Boot

If you still land back on a repair screen after disk and file repairs, treat the system as unstable but still salvageable. The priority now is your data, then a clean, working Windows install.

Use System Restore Or Uninstall Updates

  1. Launch System Restore — In WinRE, go to Troubleshoot > Advanced options > System Restore. Pick a restore point from a date before the loop started and let Windows roll back system files and settings.
  2. Remove Problem Updates — If the loop began right after a feature update, choose Uninstall Updates in the same menu and remove the latest quality or feature update, then test a reboot.

If neither restore nor update removal helps, you may need to reset Windows while trying to save your files.

Reset This PC While Keeping Files

  1. Start A Reset From WinRE — Choose Troubleshoot > Reset this PC.
  2. Pick Keep My Files — Select the option that keeps personal files but removes apps and settings. This often clears damaged system components that repairs could not fix.
  3. Complete The Reset — Follow the prompts. The process reinstalls Windows while keeping your user data on the system drive, then restarts into a fresh desktop.

If the reset feature reports errors or refuses to run, a full reinstall from a USB installer may be the only path left. In that case, connect the drive to another PC or use a live USB to copy documents, photos, and other irreplaceable files before you wipe the disk.

Preventing Future Automatic Repair Loops

Once your PC is healthy again, a few habits greatly reduce the chance of seeing the same loop in the near term. The goal is to keep system files stable, shut the machine down cleanly, and catch drive problems early.

  • Install Updates On A Stable Power Source — Run big Windows updates only when the device is plugged in and unlikely to lose power midway through.
  • Avoid Sudden Power Cuts — Always shut down from the Start menu instead of holding the power button, and use a UPS for desktops in areas with frequent outages.
  • Watch Driver Changes — When a new graphics or storage driver causes crashes, roll it back quickly through Device Manager instead of forcing repeated restarts.
  • Run Disk Health Checks Regularly — Use built-in tools like chkdsk or third-party SMART readers every few months, and replace drives that start reporting errors or slowdowns.
  • Keep Regular Backups — Store copies of your files on an external drive or cloud service so repairs and reinstalls stay less stressful.

The preparing automatic repair screen is a warning sign, not a sentence. With steady steps, a bit of patience, and the right order of tools, you can usually recover Windows, rescue your files, and spend less time staring at a looping logo on start-up.
