      How to Enable or Disable Secure Boot in UEFI
      Secure Boot - Enable or Disable in UEFI Infosmall1   Information
      UEFI (replaces BIOS) has a firmware validation process, called secure boot, which is defined in Chapter 27 of the UEFI 2.3.1 specification. Secure boot defines how platform firmware manages security certificates, validation of firmware, and a definition of the interface (protocol) between firmware and the operating system. Secure boot prevents “unauthorized” operating systems and software from loading during the startup process. 

      Quick summary



      • UEFI allows firmware to implement a security policy
      • Secure boot is a UEFI protocol not a Windows 8 feature
      • UEFI secure boot is part of Windows 8 secured boot architecture
      • Windows 8 utilizes secure boot to ensure that the pre-OS environment is secure
      • Secure boot doesn’t “lock out” operating system loaders, but is a policy that allows firmware to validate authenticity of components
      • OEMs have the ability to customize their firmware to meet the needs of their customers by customizing the level of certificate and policy management on their platform
      • Microsoft does not mandate or control the settings on PC firmware that control or enable secured boot from any operating system other than Windows

      This tutorial will show you how to enable or disable secure boot in your PC's UEFI settings. 

      Any PC with a Windows 8 logo sticker has secure boot enabled by default. Secure boot can make Windows 8 very resistant to low-level malware such as rootkits. 



      If you would like to post screenshots of your motherboard's secure boot settings, then please do. Here are some others posted so far:





      Secure Boot - Enable or Disable in UEFI Warnsmall   Warning
      Arm based Windows RT PCs and devices will have a locked boot loader, so you will not be able to disabled secure boot on them.

      Do not enable secure boot with Windows 7, Vista, or XP installed. If you do, these OSs will not boot until secure boot is disabled.


      EXAMPLE: "SecureBoot isn't configured correctly" watermark in Windows 8.1
      NOTE: You will see this watermark on the bottom right corner of your desktop if you have Windows 8.1 installed with UEFI and secure boot is not configured correctly even when enabled. To remove this watermark, you will just need to enable and configure secure boot correctly.
