Fixing Error Code 0xc0000225 manually

Here are the solutions to fix the 0xc0000225 error and get your Windows system up and running again.

1. Use Windows Recovery Environment (WinRE)

If your PC doesn’t automatically boot to WinRE after several failed attempts, you may need to use Windows installation media. Create a bootable USB or DVD from another PC if necessary.

Booting into WinRE:

1. Insert the Windows installation media and restart your PC.
2. Press the key to boot from the media (F12, F10, Esc, etc., depending on your PC).
3. On the Windows Setup screen, select your language and preferences, then click Next.
4. Click Repair your computer.

2. Automatic Repair

1. Navigate to Troubleshoot > Advanced options > Startup Repair.
2. Select your operating system and let Windows attempt the repair.

3. Rebuild the BCD

If Startup Repair doesn’t fix the issue, try rebuilding the BCD manually:

1. In the WinRE, go to Troubleshoot > Advanced options > Command Prompt.
2. Type the following commands, pressing Enter after each:

   bootrec /fixmbr
   bootrec /fixboot
   bootrec /scanos
   bootrec /rebuildbcd

4. Check Disk for Errors

Corrupted disk sectors can cause BCD errors. Use the Check Disk tool to find and repair errors:

1. In the Command Prompt, type chkdsk /r c: (replace c: with the letter of your Windows installation drive) and press Enter.
2. Restart your PC after the scan and repair process.

5. Set the Correct Boot Order

Ensure your BIOS is set to boot from the correct device:

1. Enter the BIOS setup (the key to press varies by manufacturer but is often F2, F10, Esc, or Del).
2. Navigate to the boot order settings.
3. Set the drive containing Windows as the first boot device.
4. Save changes and exit the BIOS.

6. Restore System to a Previous State

If you have system restore points:

1. In WinRE, go to Troubleshoot > Advanced options > System Restore.
2. Follow the prompts to select a restore point before the error started.

7. Reset or Reinstall Windows

As a last resort, consider resetting Windows (which keeps your files but removes apps and settings) or performing a clean installation (which removes all data):

1. In WinRE, go to Troubleshoot.
2. Choose Reset this PC for a reset or use the installation media to perform a clean installation, following the on-screen instructions.
