Boot Settings details

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 UEFI by default.
Boot Sequence Enables or disables the Boot Sequence Retry feature. If this option is set to Enabled and the system fails to boot,
Retry the system re-attempts 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. This option
is set to Disable by default.
Boot Option Configures the boot sequence and the boot devices.
