Symptoms
- Windows 11 is stuck on Preparing Automatic Repair
- Preparing Automatic Repair repeats in a loop
- Startup Repair cannot repair your PC
- Windows restarts before sign-in
- Automatic Repair appears after a failed update or setup attempt
Common causes
- Failed update
- Driver conflict
- Boot file damage
- External device confusion
- Storage detection problem
- Drive health issue
Before you start
Prepare a safe repair session
- Back up important files before reset, reinstall, partition, firmware, or storage steps.
- Disconnect nonessential USB devices.
- Write down the exact recovery message.
- Do not reset before checking backup and storage clues.
Quick path
Try the safest checks first
Step 1
Disconnect external devices and let repair run once
A dock, external drive, or USB device can confuse boot. Startup Repair is a low-risk first recovery step.
Exact path to follow
- 1Power off.
- 2Disconnect printers, docks, external drives, and nonessential USB devices.
- 3Start the PC.
- 4Let Automatic Repair or Startup Repair run once.
Expected result
Windows either boots, reports a repair result, or returns to Advanced options.
If it worked
Stop here and reconnect devices one at a time.
If it did not work
Open Advanced options.
Did Windows boot after removing external devices or Startup Repair?
Yes
Stop and reconnect devices one by one.
No
Continue to Safe Mode and restore options.
Step 2
Use Advanced options instead of restart loops
Repeated power cycling can make recovery harder. Advanced options give controlled repair choices.
Exact path to follow
- 1Choose Advanced options.
- 2Open Troubleshoot.
- 3Choose Advanced options again.
- 4Start with Startup Repair if it was not already tried.
Expected result
You reach controlled recovery tools.
If it worked
Use the repair result to choose the next path.
If it did not work
Try Safe Mode or System Restore if available.
Did the quick path fix the problem?
Yes
Stop here and write down what worked.
No
Continue with the detailed steps below.
Detailed steps
Move one step at a time
Step 3
Try Safe Mode for recent driver or app problems
Safe Mode can let you remove a recent driver, app, or update that prevents normal startup.
Exact path to follow
- 1Open Startup Settings from Advanced options.
- 2Restart into Safe Mode.
- 3Remove only the recent driver/app that matches the timing.
- 4Restart normally.
Expected result
Windows either boots normally or the loop continues.
If it worked
Stop and avoid reinstalling.
If it did not work
Try System Restore or uninstall recent update if available.
Can Windows start in Safe Mode?
Yes
Remove the recent matching cause and restart normally.
No
Use restore or update removal choices.
Step 4
Use System Restore or uninstall recent update only when timing fits
Restore and update removal can undo a recent cause without wiping files, but should match the symptom timing.
Exact path to follow
- 1Choose System Restore if a restore point exists.
- 2Or choose Uninstall Updates if the loop began right after an update.
- 3Read the screen carefully.
- 4Restart and test.
Expected result
Windows either boots or returns to recovery with a clearer failure.
If it worked
Stop and back up important files.
If it did not work
Check storage detection before reset or reinstall.
Advanced checks
Use only after the safe path
Step 5
Check storage detection before reset or reinstall
If Windows recovery cannot see the internal drive, reset or reinstall may not be the right next step.
Exact path to follow
- 1Enter BIOS/UEFI.
- 2Check whether the internal drive appears.
- 3Write down the model or capacity.
- 4Stop if the drive is missing, clicking, or intermittent.
Expected result
You know whether this is a boot repair problem or a storage detection problem.
If it worked
Use storage/setup related guides based on the clue.
If it did not work
Ask a technician before data-loss steps.
Stop here
Stop before reset or reinstall
Automatic Repair loops are scary, but reset and reinstall can remove apps, settings, or files. Protect data first.
- Stop if files are not backed up.
- Stop if storage is missing or clicking.
- Stop before destructive partition choices.
Mistakes to avoid
- Do not force restart in a loop.
- Do not reset or reinstall as the first step.
- Do not delete partitions.
- Do not ignore clicking drive noises.
When to ask a technician
- The drive is missing in BIOS/UEFI.
- The drive clicks or disappears.
- Startup Repair and Safe Mode both fail and files are not backed up.
- The PC shuts down repeatedly.
Guided repair FAQ
Should I keep restarting when Preparing Automatic Repair loops?
No. Let repair run once, then use Advanced options. Repeated forced restarts can make diagnosis harder.
Will Startup Repair delete my files?
Startup Repair is designed to repair startup problems, not erase personal files. Reset, reinstall, or partition actions are the data-risk steps.
What if Safe Mode does not start?
Use System Restore, uninstall recent update if timing fits, and check storage detection before reset or reinstall decisions.
Can a missing SSD cause an Automatic Repair loop?
Yes. If BIOS/UEFI cannot see the internal drive, recovery may loop because Windows cannot reliably read the boot files.
