How to Run SFC from the Windows Recovery Environment?

This guide explains how to use the System File Checker (SFC) from the Windows Recovery Environment (WinRE) to repair corrupted or missing system files, and how to recover missing files using MiniTool Power Data Recovery.

Understanding SFC and WinRE

SFC (System File Checker) is a built-in Windows utility that scans and repairs damaged or missing system files. WinRE (Windows Recovery Environment) is a troubleshooting toolset accessible when Windows fails to boot normally.

Running SFC from WinRE

If your system won't boot, follow these steps to run SFC from WinRE:

Step 1: Accessing WinRE

1. Power on your computer.
2. When the Windows logo appears, repeatedly press and hold the power button to force a shutdown (repeat this three times).
3. Automatic Repair should start.

4. Select Advanced options.

This launches WinRE.

Step 2: Running the SFC Scan

1. Choose Troubleshoot > Advanced options > Command Prompt.

2. Type sfc /scannow and press Enter.

Wait for the scan to complete.

Troubleshooting: "Windows Resource Protection could not start the repair service"

If you encounter this error, use the offline SFC command:

sfc /scannow /offbootdir=<disk> /offwindir=<folder></folder></disk>

Replace <disk></disk> with the boot drive letter (often D: in WinRE) and <folder></folder> with the Windows installation folder (usually \Windows).
