This tutorial will show you how to confirm if Secure B<\/b>oot<\/b> is enabled or disabled in your UEFI settings from insideWindows 8 <\/b>and 8.1<\/b>.You must be signed in as an administrator<\/b> to be able to do the steps in this tutorial.<\/div>\n<\/div>\n

\"Note\"\u00a0\u00a0 Note<\/div>\n
UEFI<\/b> (replaces BIOS) has a firmware validation process, called secure boot<\/b>, 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 \u201cunauthorized\u201d operating systems and software from loading during the startup process.Quick summary<\/b><\/p>\n
    \n
  • UEFI allows firmware to implement a security policy<\/li>\n
  • Secure boot is a UEFI protocol not a Windows 8 feature<\/li>\n
  • UEFI secure boot is part of Windows 8 secured boot architecture<\/li>\n
  • Windows 8 utilizes secure boot to ensure that the pre-OS environment is secure<\/li>\n
  • Secure boot doesn\u2019t \u201clock out\u201d operating system loaders, but is a policy that allows firmware to validate authenticity of components<\/li>\n
  • 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<\/li>\n
  • Microsoft does not mandate or control the settings on PC firmware that control or enable secured boot from any operating system other than Windows<\/li>\n<\/ul>\n
