this version of vanguard requires secure boot to be enabled in order to play

You need to enable Secure Boot in your BIOS settings to resolve this issue. Here’s a general guide:

  1. Restart your PC and enter the BIOS setup. Common keys for this are F2, F10, DEL, or ESC. You might see a prompt on the screen during startup telling you which key to press.
  2. Find the Secure Boot settings. Usually, it’s under the "Boot" tab or "Security" tab.
  3. Enable Secure Boot. If it’s disabled, toggle it to enabled. Note: If your system is using Legacy BIOS, you need to switch to UEFI. Changing this incorrectly can prevent your system from booting.
  4. Save and Exit BIOS. This is usually done by pressing F10 or selecting the "Save and Exit" option.
Important: Before enabling Secure Boot, ensure your system is not using Legacy BIOS to avoid boot issues. Consult your motherboard’s manual or manufacturer’s website for detailed instructions.
