Fix BSOD Error Windows Error Code 0xc0000185 in Windows 11 / 10

 The Windows error code 0xc0000185 typically indicates a problem with the boot process of your computer. This error can occur due to various reasons, such as corrupted system files, hardware issues, or incorrect boot settings. Here are some steps you can try to fix this error:

1. Check Hardware Connections: Ensure that all hardware components, like RAM modules, hard drives, and cables, are properly connected. Sometimes loose connections can cause boot errors.

2. Boot from Installation Media:

   a. Create a Windows installation USB or DVD.

   b. Boot your computer from the installation media.

   c. Choose the language and region settings, then click "Next."

   d. Click on "Repair your computer" at the bottom left corner.

   e. Go to "Troubleshoot" > "Advanced options" > "Startup Repair." Follow the prompts to repair the startup process.

3. Use Command Prompt:

   a. Follow steps 1 to 4 from the previous method.

   b. Instead of selecting "Startup Repair," choose "Command Prompt" from the Advanced options.

   c. Run the following commands one by one:

      ```

      bootrec /fixmbr

      bootrec /fixboot

      bootrec /scanos

      bootrec /rebuildbcd

      ```

   d. Restart your computer and see if the issue is resolved.

4. Check Disk for Errors:

   a. Boot from installation media as mentioned earlier.

   b. Choose "Command Prompt" from the Advanced options.

   c. Run `chkdsk /f /r C:` (assuming C: is your system drive). This will check and repair disk errors.

   d. Restart your computer after the process is complete.

5. Reset BIOS Settings:

   Incorrect BIOS settings could cause boot issues. Access your computer's BIOS settings and ensure that the boot order is set correctly, with the system drive as the first boot option.

6. Perform System Restore:

   If you have a recent system restore point, you can use it to revert your system settings to a point when it was working correctly.

7. Check for Hardware Issues:

   If none of the above steps work, it's possible that there might be a hardware issue causing the error. You may need to test your RAM, hard drive, and other components for potential problems.

8. Reinstall Windows:

   If all else fails, you might consider reinstalling Windows. This should be your last resort as it will erase all data on the system drive.

Remember to back up your important data before attempting any major changes to your system.

If you're not comfortable performing these steps on your own, or if the issue persists despite your efforts, it might be a good idea to seek help from a professional technician.

Here are some additional tips to help you avoid the error code 0xc0000185:

1. Restart your computer. This may seem like a simple solution, but it can sometimes fix minor problems with the BCD store.
2. Run the System File Checker (SFC) scan. The SFC scan is a built-in tool that can scan your computer for corrupted system files and repair them. To run the SFC scan, open Command Prompt as an administrator and type the following command:

sfc /scannow

3. Rebuild the BCD store. If the SFC scan does not fix the error, you can try rebuilding the BCD store. To do this, follow these steps:

   1. Boot your computer from a Windows installation disc or USB drive.
   2. When you reach the Welcome screen, click on Repair your computer.
   3. In the Choose an option screen, click on Advanced options.
   4. In the Advanced options screen, click on Command Prompt.
   5. In the Command Prompt window, type the following command and press Enter:

bootrec /rebuildbcd

6. This will rebuild the BCD store from the Windows installation files on the disc or USB drive.

7. Once the BCD store has been rebuilt, restart your computer and see if the error is resolved.

8. Restore your computer to a previous point in time. If you have created a system restore point, you can use it to restore your computer to a time before the error occurred. This will undo any changes that may have caused the error.

9. Contact Microsoft support. If you have tried all of the above steps and the error is still occurring, you may need to contact Microsoft support for further assistance.

• Keep your Windows operating system up to date. Microsoft regularly releases updates that can fix bugs and security vulnerabilities that may cause BSOD errors.
• Avoid installing third-party drivers or software that is not from a trusted source. Untrusted drivers and software can sometimes conflict with Windows and cause BSOD errors.
• Make sure your computer hardware is compatible with Windows. If your computer is not compatible with Windows, it may be more prone to BSOD errors.
• Back up your important files regularly. If you do experience a BSOD error, you will be able to restore your files from a backup.

I hope this helps!
