UEFI Optimized Boot

Use this option to control whether the system BIOS boots using native UEFI graphic drivers. Leave it enabled for compatibility with VMware ESXi on a system configured for UEFI Boot Mode, and to enable and use Secure Boot Mode.

Before changing this setting, consider the following:

  • If you are running a Microsoft Windows 2008 R2 operating system, and the system is configured for UEFI Boot Mode, this option must be set to disabled. Legacy BIOS Mode components are needed for video operations in Windows.

  • Boot Mode must be set to UEFI Mode when this option is enabled.
  • This option must be enabled to:
    • Enable and use Secure Boot.

    • Operate VMware ESXi.
