Summary: Stuck on 'Preparing Automatic Repair' or 'Automatic Repair couldn't repair your PC'? Rebuild boot files, run SFC offline, and break the Windows 11 loop.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
Windows 11 keeps cycling through **Preparing Automatic Repair** → **Diagnosing your PC** → **Automatic Repair couldn't repair your PC** → restart → repeat. It cannot fix itself and never reaches the desktop. The cause is usually corrupt boot configuration, damaged system files, a bad update or driver, or a failing drive.

> Seeing a clean blue screen with INACCESSIBLE_BOOT_DEVICE instead? Use [that fix](https://www.mytechnician.tech/tips/fix-inaccessible-boot-device-windows-11/). A black screen with no logo at all? See [black screen on boot](https://www.mytechnician.tech/tips/fix-black-screen-on-boot-windows-11/).

## Before You Start: Two Warnings
* **Get your BitLocker recovery key first.** Any boot repair can trigger a recovery prompt. Sign in at `account.microsoft.com/devices/recoverykey` on your phone and save the key. If you are already stuck at that prompt, see [fix the BitLocker recovery key loop](https://www.mytechnician.tech/tips/fix-bitlocker-recovery-key-loop-windows-11/).
* **Your files are almost certainly fine.** This is a boot problem, not data loss. Do not jump to a clean install.

## Quick Fix: Disconnect Everything External
Unplug USB drives, external disks, card readers, and dongles, then power on. A removable drive earlier in the boot order traps the PC in this loop surprisingly often—and it costs nothing to rule out.

## Step 1: Reach Advanced Options
On the **Automatic Repair couldn't repair your PC** screen, click **Advanced options**.

If the loop restarts before you can click anything, force it: hold the power button for five seconds during boot, three times in a row. The fourth boot enters the recovery environment.

## Step 2: Uninstall the Latest Update
If the loop started right after Patch Tuesday, this is the highest-probability fix.

1. **Troubleshoot** → **Advanced options** → **Uninstall Updates**.
2. Choose **Uninstall latest quality update**.
3. If that fails or does not apply, try **Uninstall latest feature update**.
4. Restart.

## Step 3: Run Startup Repair Once
**Advanced options** → **Startup Repair**. Let it run to completion—it can take 20 minutes or more. Run it once; if it fails twice, it will not succeed on the third attempt and you should move on.

## Step 4: Rebuild the Boot Configuration
Open **Advanced options** → **Command Prompt**.

First find the right drive letter—in the recovery environment, Windows is often **not** on C:. Run `diskpart`, then `list volume`, note which volume holds Windows (usually the large NTFS one), then `exit`.

```cmd
bootrec /fixmbr
```
```cmd
bootrec /fixboot
```
```cmd
bootrec /scanos
```
```cmd
bootrec /rebuildbcd
```

If `bootrec /fixboot` returns **Access is denied** (common on UEFI systems), rebuild the boot files instead:

```cmd
bcdboot C:\Windows /s C: /f UEFI
```

Substitute the correct drive letter for `C:` if `list volume` showed something different.

## Step 5: Repair System Files and Check the Disk
```cmd
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
```
```cmd
chkdsk C: /f /r
```

`chkdsk /r` on a large drive can take hours—leave it running. If it reports bad sectors, the drive is failing and the repair is a temporary reprieve at best; back up as soon as you can boot.

## Step 6: Turn the Loop Off to See the Real Error
Automatic Repair hides the underlying failure. Disabling it lets Windows show the actual stop code, which is far more actionable.

```cmd
bcdedit /set {default} recoveryenabled No
```

Restart. You will now either boot normally, or get a specific blue-screen code you can look up—see [use Event Viewer to find why your PC crashed](https://www.mytechnician.tech/tips/how-to-read-event-viewer-find-crash-cause/) once you are back in.

Re-enable it afterwards:

```cmd
bcdedit /set {default} recoveryenabled Yes
```

## Step 7: Boot Safe Mode and Undo the Change
**Advanced options** → **Startup Settings** → **Restart** → press **5** for Safe Mode with Networking. From there:

* [Roll back a bad update](https://www.mytechnician.tech/tips/fix-windows-11-after-bad-update-rollback/).
* Run System Restore (`rstrui`) to a point before the problem—see [create and use a system restore point](https://www.mytechnician.tech/tips/create-system-restore-point-windows-11/).
* Uninstall a recently installed driver, especially graphics or storage.

## Step 8: Rescue Your Files Before Anything Drastic
If nothing above works, copy your data out before reinstalling. From **Command Prompt** in the recovery environment:

```cmd
notepad
```

Use **File** → **Open**, set the file type to **All Files**, and browse to `C:\Users\<you>` with a USB drive attached—Explorer's file dialog lets you copy and paste. It is clumsy but it works without any extra tools.

## What Not to Do
* **Don't run `bootrec /fixmbr` on a UEFI/GPT system expecting a fix.** It targets the legacy MBR; `bcdboot` is the correct tool there.
* **Don't reset the PC as step one.** Work through the repairs first; reset is recoverable but slow and loses installed applications.
* **Don't reinstall Windows over a failing drive.** Test the disk first, or you will repeat the whole exercise in a fortnight.

## Still Looping?
* If `chkdsk` reports bad sectors or `bootrec` cannot find a Windows installation, suspect the drive: [check SSD or hard drive health](https://www.mytechnician.tech/tips/check-ssd-hard-drive-health-windows-11/).
* Last resort that keeps your files: [reinstall Windows without losing data](https://www.mytechnician.tech/tips/reinstall-windows-without-losing-data/).
