  1. Secure boot not detected


    My Asus board has had the settings for Secure boot on since installing windows 10 but the Windows 11 check keeps saying it isn't detected. CSM in my bios has UEFI and legacy for its support if I leave it on UEFI and legacy I can boot to windows just fine. All the drivers are set to try UEFI first before looking for legacy ones. Windows wont boot if its strictly on UEFI only. Why isn't it detecting that UEFI for secure boot is enabled when the setting shows it?

  2. Windows 8 Secure Boot Feature: Not So Secure?

    So Linux is switching to secure boot also? Or they have to because of UEFI?

    Windows 8 Secure Boot Feature: Not So Secure?

    • Linux

    • Oh and OSX
    Here is a statement from a Kernal Developer at Red Hat:

    I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.

    secure boot vioaltion - invalid signature detected

    Hi,

    For possible resolution regarding the error "'secure boot violation", see the steps below:

    • Start the computer/PC, and enter the BIOS by pressing
      F2
      or DEL key.
    • Go to Advanced Mode by pressing F7. Find the
      BOOT tab at the top.
    • Scroll down until you see the Secure Boot.
    • Enter the setting and Key Management, and select Clear Secure Boot keys.
    • Confirm that you will delete the keys. Escape out of the main window, and go to the
      EXIT tab.
    • Look for the option to Save Configuration and Reset.

    Let us know how it goes.
