Fix: Secure Boot is Greyed Out on Windows 11

  1. Check Your Computer's Manufacturer Documentation:

    • Verify if your computer's manufacturer has any specific requirements or limitations regarding Secure Boot. Some computers may have certain restrictions.
  2. Access UEFI/BIOS Settings:

    • Restart your computer and access the UEFI or BIOS settings. The key to enter these settings varies depending on your computer's manufacturer (e.g., F2, F12, Delete, or ESC). Refer to your computer's manual or the manufacturer's website to find the correct key.
  3. Disable Fast Startup:

    • Sometimes, Windows Fast Startup can interfere with UEFI settings. Disable it by following these steps:
      • Open Control Panel.
      • Go to "Power Options."
      • Click on "Choose what the power button does" on the left sidebar.
      • Click "Change settings that are currently unavailable."
      • Uncheck "Turn on fast startup (recommended)" and save your changes.
  4. Update BIOS/UEFI Firmware:

    • Check if there are any BIOS/UEFI updates available for your computer on the manufacturer's website. Updating your firmware may resolve compatibility issues with Secure Boot.
  5. Reset UEFI/BIOS Settings to Default:

    • Within your UEFI/BIOS settings, there should be an option to reset settings to default. This can sometimes resolve issues with greyed-out options.
  6. Clear Secure Boot Keys:

    • Within the UEFI/BIOS settings, there might be an option to clear Secure Boot keys or certificates. Clearing these and then re-enabling Secure Boot may help.
  7. Check for TPM (Trusted Platform Module) Requirements:

    • Some systems may require a TPM for Secure Boot to be enabled. Ensure your computer has a TPM module, and it's enabled in the UEFI/BIOS.
  8. Consult Manufacturer Support:

    • If you've tried all the above steps and the issue persists, contact your computer's manufacturer's support for further assistance.

Remember that changing UEFI/BIOS settings can have a significant impact on your computer's functionality, so proceed with caution and make sure you understand the potential consequences of any changes you make. Additionally, creating a backup of important data is always a good practice before making any major system changes.
