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