How to Fix Kernel Security Check Error in Windows 10

Windows 10 has a lot of problems that a lot of people are facing. One of those problems is running into a blue screen of death that lists the error as Kernel Security Check Error. It causes your computer to shutdown and restart after a few seconds. It can cause you to lose your data if you are currently working on anything, and the computer does not save it automatically. In a case of this error, the following error screen is shown.

A kernel is basically the main section of the operating system that interacts with the hardware. When you make a request from within your computer, say to access a file on your hard drive, the operating system asks the Kernel for the permission to access it and then displays the file to you. If anything with the kernel fails, the operating system can not interact with the hardware, and runs into a crash state. This is what is happening here, in a nutshell, so now let’s get to fixing this issue that we’re facing on our computer.

There are two ways in which you can fix this problem, one involves creating a USB Bootable Drive or a CD that came with your computer, and the other just needs you to boot into the safe mode and run a few commands.

Fix Kernel Security Check Error using Safe Mode

When Windows fails to boot, it will automatically ask you what should be done, but just in case it doesn’t you’re gonna have to bring up that option manually. Basically, you want to boot into the safe mode.

• Open your Start Menu and hold the Shift Key when you press the Power button. Next, while keeping the Shift key pressed, click on Restart, and you should be brought to a screen that has many options.
• At that point, choose Troubleshooting and then Advance Options and then finally click on Startup Settings and boot into the Safe Mode. If you fail to load into safe mode, move to the second solution and skip the next steps in this solution.
  
• When you’re booted into the Safe Mode in Windows 10, open the Start Menu and type CMD, right click on Command Prompt and choose Run as Administrator.
• Type “sfc /scannow” in the Command Prompt, and wait for it to finish scanning for errors. If it finds any, it’ll try to fix them on its own.
• Once it’s done, Open Start Menu and type “mdsched.exe” and run the tool. When it is opened, click on “Restart now and check your problems”.

That should be it. You should now be able to boot into your computer without any problem. However, if your Memory Tool Test shows that there were some errors, you might need to get your RAM checked. It might be because of a faulty RAM.

Fix Kernel Security Check Error using BCDEdit

This method of fixing the Kernel Security Check Error requires you to have a bootable USB Drive for your Windows installation or a recovery CD that came with your computer. If you don’t have any of those, you’ll need to create a recovery disk. I’ve already written an article on how to create a recovery media for your Windows 10 installation, so just follow that and come back here.

• Plug in your USB Drive, and boot into it. When Windows setup begins, click Next and then choose Troubleshoot.
• Inside Troubleshoot, choose Advanced Options and then Command Prompt.
• Wait for a few seconds till the command prompt loads, and then type in “BCDEDIT /SET {DEFAULT} BOOTMENUPOLICY LEGACY”
• When the command executes completely, type “exit” to get out of the Command Prompt
• At this screen, choose Continue to boot into your computer and hopefully, you would have resolved this error.
