Boot settings
Use the Boot settings to set the boot mode to either BIOS or UEFI. The settings also
enable you to specify the boot order.
CAUTION
Changing the default settings may make the node unusable. Dell EMC
recommends only making changes under the direction of Dell EMC tech support.
Note
Do not change the boot settings, as they are set by VxFlex OS.
BIOS: The BIOS Boot Mode is the legacy boot mode. It is maintained for
l
backward compatibility.
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, also 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.
