Thank you for posting in the Microsoft Community. I understand that your Windows 11 bootloader files were corrupted during the update process, and I'm here to help. To help narrow down the root cause and avoid repeating methods you have already attempted, could you share what specific troubleshooting steps you have already tried? Also, did you encounter any other error messages or codes? like have you already tried running Startup Repair, booting into Safe Mode, or entering commands in the Command Prompt?
