Error 0xc0000225 During Windows Boot: Causes and Fixes

Error 0xc0000225 is a common issue that can occur when Windows fails to start. This error usually indicates that the system cannot locate the necessary boot files or that the disk partition table is corrupted. In this guide, we’ll cover the primary reasons for this error and provide step-by-step solutions to help resolve it.

Main Causes of Error 0xc0000225

There are several common causes for this error, including:

• Corrupted or missing Boot Configuration Data (BCD) files.
• Damaged partition table on your hard drive or SSD.
• Hardware issues, such as a failing hard drive.
• Incorrect BIOS/UEFI settings, such as mismatched boot modes (Legacy or UEFI).
• Malware or virus attacks affecting critical system files.

How to Fix Error 0xc0000225

1. Use Windows Recovery Tools

One of the first steps is to use the built-in Windows recovery tools. Follow these steps:

• Boot from a Windows installation USB or DVD.
• Select "Repair your computer" instead of "Install now," then navigate to "Troubleshoot" and open "Command Prompt."
• Enter the command bootrec /rebuildbcd to repair the Boot Configuration Data.

2. Run System File Checker

To check and repair missing or corrupted system files, use the System File Checker (SFC) tool:

• Open Command Prompt and type sfc /scannow. Wait for the process to complete.

3. Check Disk for Errors

If the issue is related to disk corruption, try running the chkdsk command:

• In Command Prompt, type chkdsk /f /r and restart your system.

4. Adjust BIOS/UEFI Settings

Ensure that your BIOS/UEFI settings are correctly configured. If you are using UEFI mode, make sure UEFI boot is enabled in the BIOS. Incorrect settings can lead to boot errors like 0xc0000225.

5. Use System Restore

If you have restore points set up, you can revert your system to a previous state using System Restore:

• Boot from the installation media and choose "System Restore."
• Select a restore point to roll back your system to an earlier, working state.
