Windows 10 Secure Boot is an important module in Microsoft’s operating system as it helps reinforce your PCs security by blocking malware and other potentially unsafe programs from accessing the boot partition during startup.

The UEFI( Unified Extensible Firmware Interface) specification’s functionality indeed effectively replaces the conventional BIOS by checking the signatures of various pieces of boot software such as UEFI firmware drivers (Option ROMs), EFI applications, besides the operating system.

This makes it a handy component to have running during the Windows 10 system start-up process.

However, sometimes the computer displays secure boot failure errors when attempting to complete the involved checks and the PC fails to start.

This could be because of compatibility issues such as a recently installed hardware like a graphics card being incompatible with Secure Boot.

So how can you troubleshoot the secure boot failure windows 10 issue? Well, there are several working solutions as discussed next.

Secure Boot Failure Windows 10 Error: Suggested Fixes

Fix 1: Turn Off Windows 10 Secure Boot

Steps:

  1. Force shut your PC by long pressing the power button.
  2. Now switch on the computer and access the BIOS This is by typically pressing a specified key on the keyboard during the boot-up sequence. The commonly used BIOS access keys are F1, F2, F10, F12, and Esc depending on the manufacturer and computer model.
  3. Now locate the Windows 10 Secure Boot setting mostly found under Security.
  4. Using the right key, change it to Disabled.Secure Boot Failure Windows 10
  5. Save the changes, exit, and retry boot.security boot fail

In certain instances, you may have to additionally change other firmware to enable legacy support and load the Compatibility Support Module (CSM).

This method works only if your PC can boot..

  1. While holding down the Shift key, go to start then choose Restart.
  2. From the next screen, Go to Troubleshoot.disable secure boot windows 10 asus

  4. Then click UEFI Firmware Settings.
  5. Again find the Secure Boot option, and switch it to Disabled.
  6. Save these changes and exit to allow the PC to reboot.

Overall, since you disable Secure Boot via the PC’s BIOS menus, the procedure of disabling it varies among PC manufacturers.

This means you may have to refer to your manufacturer for assistance if the above highlighted steps don’t work.

Also note that re-activating Secure Boot after this may need you to factory reset your PC so perhaps you can attempt the other solutions first.

Again be cautious when adjusting the BIOS settings as a small misconfiguration can cause further startup trouble.
