How to fix Error Code 0xc00000f in Windows 11 ,10

When you are running Windows, the last thing you want to experience is seeing a Blue Screen of Death or in short, a BSOD crash where your computer screen suddenly goes all blue and only this error message shows up “The Boot Configuration Data for your PC is missing or contains errors“. This issue can occur while the system is booting up, ultimately not letting you boot up the system at all. Here we have discussed some very easy solutions that can fix the issue very quickly.


You have to fix the Master Boot Record on your system. In order to do so, you have to access the Windows Recovery Environment. We have shown the steps how to do that –

1. At the first step, shut down your device completely.

2. Once you are sure that the device is switched off completely, tap on the power button once to start it up. When you reach the manufacturer’s logo screen, press-hold the power button again to switch off the device completely.

3. Repeat these steps of force-boot-shutdown 2 more times.

4. At the third time, let the system boot normally. While the system boots up, you will see the Automatic Repair screen has opened up.

Fix 1 – Detach all external devices

Before you proceed to the main solutions, make sure no other external devices are attached to the main setup.

1. Make sure the system is shut down completely.

2. Then, very carefully remove the power cord from the source. Next, check the power cable for any external defects (like ruptures, tearing, etc.).

3. At the next step, detach all the external USB devices (like any Bluetooth adapters, external HDDs) one by one from the setup.

4. Make sure there is not a single piece of an external device is connected to the system. Then, just connect the power cable to the system and turn it ON.

5. Further, make sure there aren’t any CDs/DVDs running in the slot.

6. Finally plug in the power cord and start the device.

Now, check whether the system is booting up normally or showing the error message. If that is the case, follow the next fix to fix the MBR.
