In this article, let us discuss an error ‘0xc0000225’ that occurs when you boot your PC. It can be a little hard to track what’s causing the error because the error message that comes with the code isn’t very helpful. It only reads ‘an unexpected error has occurred’ or in some cases, it may read ‘A required device isn’t connected or can’t be accessed’. These messages are not very helpful, isn’t it?
But don’t worry, in this article, we explain the reasons for this error and some simple solutions to help you resolve the error.
The main reason for ‘0xc0000225’ error is when the OS cannot find the correct system files (BCD) to boot or when the system files are damaged.
Troubleshooting steps to resolve ‘0xc0000225’ error
- Use the Automatic Repair function
This is the simplest troubleshooting step to fix the error ‘0xc0000225’. To use the repair feature, insert a Windows installation disc and select Repair your computer on the bottom left corner.
- Then click on Troubleshoot > Advanced Options
- Click on Automatic Repair
This process is designed to repair startup errors in your PC. So, wait for the repair process to complete and see if you can boot the system normally.
- Run System File Checker
SFC, short for System File Checker is a tool that is used to fix issues with system files. To run this tool, use the same steps as explained above and enter the Advanced Options menu.
In the menu, click on Command Prompt and type the following command
This command will check for corrupt or missing system files and restore them if required. Once this process completes, system files should be in good shape and you should be able to boot into your system.
- Rebuild BCD
If running SFC doesn’t do the trick, you may have to rebuild BCD manually. BCD stands for Boot Configuration Data and this file contains important information to boot your system. Any damage to this file may produce errors such as ‘0xc0000225’.
In order to resolve this error, you can rebuild BCD manually. To do so, enter the Advanced Options menu using the same steps as above and click on Command Prompt.
In the command prompt, type these commands and hit Enter after each of them.
‘Fixmbr’ command is used to write a compatible installation into the system partition. This will resolve any MBR corruption issues. ‘Fixboot’ is used to write a new boot sector to the system’s partition. This option is useful if the boot sector is damaged. ‘Rebuildbcd’ is used to completely rebuild the BCD.
Once you perform these operations, all issues related to BCD will be fixed and this should help you resolve the error. If this doesn’t help, proceed to the next step.
- System Restore
System Restore is an option that is used to restore your PC to an earlier point in time. This will undo any changes you made to your computer due to which the ‘0xc0000225’ error may be produced. To use System Restore, go to the Troubleshoot menu using the steps in solution 1.

If you have trouble with System Restore, refer system restore not working Windows 10.
