Boot Settings details
The Boot Settings screen details are explained as follows:
Option Description
Boot Mode 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 BIOS by default.
Boot Sequence Enables or disables the Boot Sequence Retry feature. If this option is set to Enabled
Retry and the system fails to boot, the system reattempts the boot sequence after 30
seconds. This option is set to Enabled by default.
Hard-Disk Failover Specifies the hard drive that is booted in the event of a hard drive failure. The
devices are selected in the Hard-Disk Drive Sequence on the Boot Option Setting
menu. When this option is set to Disabled, only the first hard drive in the list is
attempted to boot. When this option is set to Enabled, all hard drives are attempted
to boot in the order selected in the Hard-Disk Drive Sequence. This option is not
enabled for UEFI Boot Mode.
Boot Option Configures the boot sequence and the boot devices.

Choosing the system boot mode
System Setup enables you to specify one of the following boot modes for installing your operating
system:
• BIOS boot mode (the default) is the standard BIOS-level boot interface.
• Unified Extensible Firmware Interface (UEFI) boot mode is an enhanced 64-bit boot interface. If you
have configured your system to boot to UEFI mode, it replaces the system BIOS.
1. From the System Setup Main Menu, click Boot Settings, and select Boot Mode.
2. Select the boot mode you want the system to boot into.
CAUTION: Switching the boot mode may prevent the system from booting if the operating
system is not installed in the same boot mode.
3. After the system boots in the specified boot mode, proceed to install your operating system from
that mode.
NOTE: 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.
CAUTION: Switching the boot mode may prevent the system from booting if
the operating system is not installed in the same boot mode.
NOTE: Setting this field to UEFI disables the BIOS Boot Settings menu. Setting
this field to BIOS disables the UEFI Boot Settings menu.
