How to Fix the 0xc0000185 Error on Windows PC?

Hi everyone,

I recently encountered the 0xc0000185 error on my Windows PC. After booting, I get a BSoD, and sometimes it happens after a system crash. From what I’ve read, this error can occur due to:

Corrupt system files

Missing product key

Corrupt BCD (Boot Configuration Data)

Damaged storage drive

Incorrect boot configuration

I’ve tried rebooting, but it didn’t help. I’m looking for guidance on:

How to change the boot order in BIOS properly.

Using Windows installation media to repair system files and run commands like sfc /scannow and chkdsk /r.

Rebuilding BCD to fix boot issues.

Recovering files safely from an unstable or unbootable PC.

Using System Restore or reinstalling Windows if other methods fail.

Has anyone successfully fixed this error? Are there any additional tips to prevent data loss or avoid this error in the future?

Thanks in advance!

First, check your BIOS: enter it (usually F2/Delete on boot) and make sure your main drive is set as the first boot device—don’t mess with other settings. If that’s fine, create a Windows 11 USB installer on another PC, boot from it, and use Repair your computer → Troubleshoot → Advanced options. From there, run Startup Repair, then open Command Prompt and do sfc /scannow and chkdsk /r on your main drive. If Windows still won’t boot, rebuild the BCD with bootrec /rebuildbcd.
To recover files safely, you can boot from the USB and copy them to an external drive via Command Prompt or a Linux live USB. If all else fails, System Restore or a clean reinstall will work, but back up everything first. For prevention, keep your drives healthy, avoid sudden shutdowns, and occasionally check system integrity with sfc and chkdsk.
