Fix Error 0xc000000f in Windows Using Bootable Media

For this part, you need a USB stick with 8GB or more and another working computer with a relatively modern Windows version. Go to the official Windows 10 or Windows 11 installation website and download Media Creation Tool. Use that tool to create bootable media. It is a straightforward app that does not require any technical knowledge or skill. Just fire up the downloaded app and follow the on-screen instructions. Be sure to select the option to create a USB drive, not download ISO.

  1. Connect Windows installation media you have just created and boot from it. Different computers use different buttons to launch boot menu. Refer to your motherboard user manual to see what button selects boot device. Alternatively, you can boot into BIOS and select the USB drive from there.
  2. Press Shift + F10 on the welcome screen. Again, if Shift + F10 does not work, try Fn + Shift + F10. The shortcut will launch Command Prompt.
  3. In Command Prompt, type diskpart and press Enter.
  4. Next, enter list volume and press Enter.
  5. Find your system drive and check its letter. In 99.99% of cases, it is letter C.
  6. Enter exit and press Enter.
  7. Now, enter the following command:
    chkdsk C: /f

    The command initiates a mechanism that scans the selected drive for errors and applies possible fixes.

  8. Next, run the command:
    sfc /scannow /offbootdir=c:\ /offwindir=c:\Windows 

    Note that the process may take a while. Do not think your computer is stuck (unless it takes many hours to complete the process). Wait for Windows to complete the recovery. The speed of the process depends on how large and fast your system drive is. If you use old spinning hard drives, prepare to wait for a while.

  9. Run the command:
    bcdboot C:\Windows

    The command will create a new boot configuration and bring your computer back to its working state.

  10. Restart your PC and boot it as usual.

If nothing helps, try reinstalling Windows from scratch. Just beware that you might loose unsaved data and apps on drive C. Also, you can try temporarily replacing your hard drive or SSD with another one to see what causes the problem. It is possible that your system drive is about to bite the dust.

These are the steps you need to take to fix the 0xc000000f error in Windows 10, 11, and older versions.
