Configure the boot mode
You can use the Boot Settings screen to set the boot mode to BIOS or UEFI and specify the boot order. Boot Settings only
supports UEFI mode.
The UEFI is an interface between operating systems and platform firmware that 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 (for example, UEFI Secure Boot).
● Faster boot time.
You must use only the UEFI boot mode in order to boot from NVMe drives.
The BIOS Boot Mode is the legacy boot mode that is maintained for backward compatibility.
1. To view the Boot Settings screen, power on the system, and press F2.
2. Click System Setup Main Menu > System BIOS > Boot Settings.

Set the system boot mode
Use System Setup to specify one of the following boot modes for installing your operating system. UEFI boot mode (the default)
is an enhanced 64-bit boot interface. If you configured your system to boot to UEFI mode, it replaces the system BIOS.
1. From the System Setup Main Menu screen, click Boot Settings, and select Boot Mode.
2. Select the UEFI boot mode that you want the system to boot into.
CAUTION: The operating system must be installed in the same boot mode.
3. After the system boots in the specified boot mode, install your operating system from that mode.
Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit operating systems do not
support UEFI and can only be installed from the BIOS boot mode. For the latest information about supported operating systems,
see Server Operating Systems.

Description
Enables you to set the boot mode of the system. If the operating system supports
UEFI, you can set this option to UEFI. Setting this field to BIOS allows compatibility
with non-UEFI operating systems. This option is set to UEFI by default. Setting this
field to UEFI disables the BIOS Boot Settings menu.
CAUTION: Switching the boot mode may prevent the system from
booting if the operating system is not installed in the same boot mode.
Enables or disables the Boot sequence retry feature or resets the system. When this
option is set to Enabled and the system fails to boot, the system re-attempts the
boot sequence after 30 seconds. When this option is set to Reset and the system
fails to boot, the system reboots immediately. This option is set to Enabled by
default.
Enables or disables the generic USB boot placeholder. This option is set to Disabled
by default.
Enables or disables the Hard-disk drive placeholder. This option is set to Disabled by
default.
When this option is set to None, BIOS will do nothing. When set to Yes, BIOS will
delete variables of SysPrep #### and SysPrepOrder. This option is a onetime
option and resets to None when deleting variables. This setting is only available in
UEFI Boot Mode and set to None by default.
Specifies the UEFI boot sequence. Enables or disables UEFI Boot options. This option
