Windows 10 and 11 are modern and stable operating systems that usually do not annoy users with frequent crashes or cryptic errors. Still, they are complex products with hundreds of thousands of lines of code, which means pesky bugs can slide under the radar and get under your skin. The 0xc000000f error is one of the common bugs users may encounter when turning on a computer.
The 0xc000000f error usually goes hand in hand with Boot\BCD or winload.efi files. Although the problem may look terrifying for some less tech-proficient users, it is relatively easy to fix the 0xc000000f error in Windows 10 and 11. Also, this article applies to computers with Windows 7.
Windows Failed to Start 0xc000000f — What Does This Mean?
The 0xc000000f error is a sign of broken or corrupted boot configuration files. Do not panic! That does not mean your files are gone. In a nutshell, you need to repair files responsible for finding the operating system on your drive. It is a relatively simple procedure that should not take much time or effort.
0xc00000f Windows 10 Fix
Before you start running troubleshooters, try disconnecting all drives except the one with your Windows installation. If you have not connected any drives to your computer recently, you may skip this step.
If you have a desktop PC and you can access its hardware intestines, try the following:
- Turn off the PC and disconnect it from a power source.
- Hold the power button for a few seconds to discharge the system.
- Open the case and check your system drive. Make sure power and SATA cables are not damaged. They also should be properly seated in their sockets. A loose connection or a broken cable is one of the reasons why the 0xc000000f error happens to some people. If you have an M2 drive, ensure it is secured with a screw.
- Tighten cables, if necessary, close your computer and try to power it on.
If you have a laptop with non-user-replaceable drives, skip those steps and proceed with the following:
- If you want to fix the 0xc000000f error in Windows 10, turn on your computer as you usually do.
- On the error screen, press F1. Note that on laptops, you may need to press Fn + F1.
- Follow the on-screen instructions to get to Recovery.
- Click Troubleshoot.
- Select Advanced Options.
- Click Startup Repair and wait for Windows to try to restore your BCD.
- Once Windows finishes recovering your BCD, try to load the system in a normal mode.
If the previous part of the article did not help you fix the 0xc000000f error in Windows 10, proceed to the following section.
Fix 0xc000000f 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.
- Connect Windows installation media you have just created and boot from it.
- Press Shift + F10 on the welcome screen. Again, if Shift + F10 does not work, try Fn + Shift + F10. The shortcut will launch Command Prompt.
- In Command Prompt, execute the following command:
- Next, enter list volume and press Enter.
- Find your system drive and check its letter. In 99.99% of cases, it is the letter C.
- Enter exit and press Enter.
- Now, enter the following command:
chkdsk C: /f
The command initiates a mechanism that scans the selected drive for errors and applies possible fixes.
- Next, enter the command and press Enter:
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.
- Type in and run command:
The command will create a new boot configuration and bring your computer back to its working state.
- Restart your PC and boot it as usual.
