Hello
Thank you for posting in Microsoft Community forum.
The error code 0Xc0000225 usually indicates that Windows cannot find the correct system files for booting, often due to corrupted Boot Configuration Data (BCD).
Run Windows Automatic Repair: Boot from your Windows 10 installation media (USB or DVD). Select "Repair your computer" > "Troubleshoot" > "Advanced options" > "Startup Repair". This tool will attempt to fix any issues with your boot files.
Run System File Checker (SFC) and Check Disk (CHKDSK): Boot from the installation media again, go to "Troubleshoot" > "Advanced options" > "Command Prompt". Run the following commands:
- sfc /scannow to scan and repair system files.
- chkdsk c: /r to check the disk for errors and repair them.
Rebuild the BCD: In the Command Prompt, run the following commands:
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /scanos
- bootrec /rebuildbcd
Set the Active Partition: Ensure that the correct partition is set as active. In the Command Prompt, use the diskpart tool:
- diskpart
- list disk
- select disk X (replace X with your disk number)
- list partition
- select partition Y (replace Y with your Windows partition number)
- active
- exit.
These steps should help you repair the boot error without needing to reinstall Windows.
