BootSequence — Specifies the order in which a system searches for devices when trying to find an operating system to boot. The

Boot Sequence option allows users to customize the boot order and boot ability of boot devices. The UEFI BIOS allows the selection

of UEFI boot paths or Legacy boot devices.

To configure the sequence of the boot devices, verify the current status of the boot order with name and device number. Then,

provide the sequence to change the boot order. Example:
