What Does Error Code 0xc0000225 Mean?

The 0xc0000225 error is a Windows Boot Manager (Bootmgr) failure, indicating that the system cannot locate or load critical boot files. When this happens, you may see messages such as:

"Your PC needs to be repaired. The Boot Configuration Data for your PC is missing or contains errors."
"File: \Boot\BCD, Error code: 0xc0000225"

Common Causes of Error 0xc0000225

Corrupted Boot Configuration Data (BCD) – The BCD file is essential for booting Windows, and if it’s damaged, the system fails to start.
Faulty or Disconnected Hard Drive/SSD – If the storage device is failing or improperly connected, Windows cannot access boot files.
Incorrect BIOS/UEFI Settings – A misconfigured BIOS (e.g., wrong boot mode or disabled storage controller) can trigger this error.
Damaged System Files – Critical system files may be corrupted due to sudden power loss, malware, or failed updates.
Recent Windows Update or Driver Installation – A faulty update or incompatible driver can disrupt the boot process.

Understanding these causes helps in applying the right fix. The following sections will guide you through various troubleshooting methods.

Method 1: Repair Boot Configuration Data (BCD) Using Windows Recovery

If Windows fails to boot, you’ll need to use Windows Recovery Environment (WinRE) to fix the BCD.

Steps to Rebuild BCD:

Boot into Windows Recovery:
- Restart your PC and interrupt the boot process 3 times to trigger Automatic Repair.
- Alternatively, use a Windows 11 USB installation media and select Repair your computer.
Open Command Prompt:
- Go to Troubleshoot > Advanced Options > Command Prompt.
Run Boot Repair Commands:
- Execute the following commands one by one:
```
bootrec /fixmbr  
bootrec /fixboot  
bootrec /scanos  
bootrec /rebuildbcd  
```
- If the system prompts you to add an installation, type Y (Yes).
Restart Your PC:
- After executing these commands, restart your computer and check if the error is resolved.

Method 2: Check and Repair Disk Errors

A failing hard drive or SSD can cause the 0xc0000225 error. Running disk checks can help identify and fix issues.

Steps to Run CHKDSK:

Boot into WinRE (as described in Method 1).
Open Command Prompt.
Run the CHKDSK Command:
```
chkdsk C: /f /r /x  
```
- Replace C: with your system drive letter if different.
- The /f fixes errors, /r recovers bad sectors, and /x dismounts the drive.
Wait for Completion (this may take hours if the disk is large).
Restart Your PC.

If CHKDSK finds and repairs errors, the system may boot normally.

Method 3: Reset BIOS/UEFI Settings to Default

Incorrect BIOS/UEFI settings can prevent Windows from booting. Resetting them may help.

Steps to Reset BIOS/UEFI:

Restart your PC and enter BIOS/UEFI (usually by pressing F2, F12, DEL, or ESC during startup).
Load Default Settings:
- Look for an option like "Load Optimized Defaults" or "Reset to Default."
Ensure Boot Mode is Correct:
- If Windows 11 was installed in UEFI mode, ensure CSM (Legacy Boot) is disabled.
Save Changes and Exit.

If the error was due to a BIOS misconfiguration, this should resolve it.

Conclusion

The 0xc0000225 error in Windows 11 can be alarming, but it’s often fixable with the right approach. By rebuilding the BCD, checking for disk errors, and resetting BIOS settings, most users can restore their system without losing data. If these methods fail, consider performing a System Restore or reinstalling Windows as a last resort.

Preventive measures, such as regular backups and keeping your system updated, can reduce the risk of encountering such errors in the future. With patience and careful troubleshooting, you can overcome this issue and get back to using your PC efficiently.
