Using the BootSequence feature

This feature allows you to configure the order of the devices from which the system tries to start up using the BootSequence option in the BootSequence category.

BootListOption — determines the boot mode of the system. Select one of the following:

UEFI — To enable booting to Unified Extensible Firmware Interface (UEFI) capable operating systems.
Legacy (the default) — To ensure compatibility with OSes that do not support UEFI.
- NOTE: Legacy boot mode is not allowed when secure boot is enabled or legacy option ROM is disabled.

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:

DeviceName	Device Number	IsActive
Diskette	1	Active
Internal HDD	2	Active
USB Storage Device	3	Active
CD/DVD/CD-RW Drive	6	Active
Onboard NIC	5	Active

Then, to set the Internal HDD as first, USB Storage Device as second, and Onboard NIC as third; provide BootSequence as 2, 3, 5.

NOTE: The device numbers that are not mentioned are eliminated from the boot order.

Example: To see the current boot order with name, device number, and status.

Get-ChildItem -Path DellSmbios:\BootSequence | Select -expand CurrentValue

Example: To change the boot sequence.

Set-Item -Path DellSmbios:\BootSequence "2,3,4"

Example: To change the current boot mode to UEFI.

Set-Item -Path DellSmbios:\BootSequence BootListOption "Uefi"
