Boot Settings

You can use the Boot Settings screen to set the boot mode to either BIOS or UEFI. It also enables you to specify the boot

order.

● UEFI: The Unified Extensible Firmware Interface (UEFI) is a new interface between operating systems and platform

firmware. The interface consists of data tables with platform related information, boot and runtime service calls that are

available to the operating system and its loader. The following benefits are available when the Boot Mode is set to UEFI:

○ Support for drive partitions larger than 2 TB.

○ Enhanced security (e.g., UEFI Secure Boot).

○ Faster boot time.

NOTE:

You must use only the UEFI boot mode in order to boot from NVMe drives.

● BIOS: The BIOS Boot Mode is the legacy boot mode. It is maintained for backward compatibility.

To view the Boot Settings screen, power on the system, press F2, and click System Setup Main Menu > System BIOS >

Boot Settings.
