"Preparing Automatic Repair" means Windows failed to start normally and is launching its built-in recovery tool to scan for and try to fix the problem. It usually appears after a bad shutdown, a failed update, corrupt system files, or disk errors. If it finishes, Windows either boots or shows repair options. If it keeps looping, the underlying files or boot data are damaged and need manual repair.
Why this happens
Windows watches its own startup. When boot fails twice in a row, it automatically triggers Automatic Repair to diagnose the cause before it lets you back into the system.
- Unexpected shutdown: Losing power or holding the power button during boot or an update can leave files half-written.
- Failed or interrupted update: An update that did not finish can break the startup files.
- Corrupt system files: Damaged Windows files or a damaged boot configuration (BCD) stop normal startup.
- Disk errors or a failing drive: Bad sectors or a loose or dying drive can prevent booting.
- Bad drivers or software: A driver or program that loads at startup can crash the boot process.
Is this normal?
Seeing it once after a rough shutdown is normal, and it often repairs itself and boots. Seeing it every time, or getting stuck on the screen or in a repeating loop, is not normal and means the repair could not fix the problem on its own.
Does it cause any problems?
The message itself is harmless, but the situation behind it is serious: your computer will not boot into Windows until it is resolved. If the cause is a failing drive, act quickly and back up your data as soon as you can get in.
How to fix or check it
- Give it time: The scan can take 15 to 45 minutes, and longer on older hardware. Do not interrupt it too early.
- Do a full power cycle: If it is truly stuck, hold the power button to shut down, unplug for a minute (remove the battery if you can), then power on again. It sometimes boots normally on the second try.
- Open recovery options: If it lands on a blue "Automatic Repair" screen, choose Advanced options to reach the recovery menu.
- Run Startup Repair: In Advanced options, choose Troubleshoot > Advanced options > Startup Repair and let it try again.
- Boot into Safe Mode: From Advanced options, pick Startup Settings > Restart, then choose Safe Mode. If it boots, uninstall the last update or driver that caused it.
- Repair system files from Command Prompt: In Advanced options open Command Prompt and run sfc /scannow and chkdsk C: /f /r to check files and the disk.
- Break a repair loop: If it loops endlessly, in Command Prompt you can disable the automatic repair with bcdedit /set {default} recoveryenabled No so the machine attempts a normal boot and shows the real error.
- Check the drive connection: On a desktop or if you are comfortable, make sure the drive cable is seated. If the drive is not detected in the firmware, it may be failing.
- Last resort: If nothing works, a repair install or a clean reinstall of Windows will fix software damage. Back up first if you can access your files.
Frequently asked questions
How long should Preparing Automatic Repair take?
Usually 15 to 45 minutes. If it sits with no progress for well over an hour, it is likely stuck and you should power cycle and move on to Startup Repair or Safe Mode.
Will Automatic Repair delete my files?
No, the repair itself does not erase your personal files. Only choosing a reset or clean reinstall can remove data, and even then you can usually pick the option that keeps your files. Back up whenever you regain access.
Why is it stuck in a loop that never ends?
A loop means the repair cannot fix the damage automatically, often due to corrupt boot files or a failing drive. Use the recovery menu to run Startup Repair, check the disk with chkdsk, and if needed disable auto-repair to see the underlying error.
