If you’re encountering the error code 0xc0000185 on Windows 11, it typically indicates a problem with your system’s boot process or hardware connectivity. Resolving this error can restore your system’s functionality, prevent data loss, and get your PC back up and running smoothly. Before starting, ensure you have a reliable internet connection, your Windows 11 installation media (USB or DVD), and access to another working device to create recovery tools if needed.
What You’ll Need
- A working PC with internet access
- A USB flash drive (at least 8GB) or DVD for creating Windows recovery media
- Your Windows 11 product key (if prompted)
- Patience and careful attention to instructions
Step-by-Step
- Identify the Problem: Confirm that the error code 0xc0000185 is appearing during startup, often accompanied by messages about missing boot files or hardware issues.
- Create Windows 11 Recovery Media: On a working PC, download the Windows 11 Media Creation Tool from the official Microsoft website. Run the tool and follow prompts to create a bootable USB or DVD. This will be used to repair your system.
- Boot into Recovery Mode: Insert the recovery media into the affected PC. Restart the PC and boot from the USB/DVD. You may need to change the boot order in BIOS/UEFI settings (press F2, F12, Del, or Esc during startup).
- Access Advanced Options: Once booted from recovery media, select your language preferences and click ‘Next.’ Then click on ‘Repair your computer,’ followed by ‘Troubleshoot.’
- Use Startup Repair: In the Troubleshoot menu, select ‘Startup Repair.’ The system will scan and attempt to fix common startup issues. Follow on-screen instructions and wait for the process to complete.
- Run System File Checker and Disk Check: If Startup Repair does not resolve the issue, open the Command Prompt from the Advanced Options menu. Enter the following commands one by one:
chkdsk /f /r C: >sfc /scannow
Replace ‘C:’ with your Windows partition letter if different. These commands will check your disk and system files for errors and repair them.
- Rebuild Boot Configuration Data (BCD): Still in Command Prompt, run these commands to rebuild the boot configuration:
bootrec /fixmbr bootrec /fixboot bootrec /scanos bootrec /rebuildbcd
This can resolve boot-related errors causing 0xc0000185.
- Restart Your PC: Remove the recovery media and restart your PC. If the steps were successful, Windows 11 should boot normally. If not, proceed to further troubleshooting or consider reinstalling Windows.
Common Mistakes
- Not creating a proper recovery media before starting troubleshooting.
- Incorrectly modifying BIOS settings, leading to boot failures.
- Running commands in the wrong order or on the wrong drive letter.

Tips
- Always back up your data regularly to prevent data loss during repairs.
