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, shortform, and device number.

Then, provide the sequence to change the boot order. For example, see the following table:

Table 5. Example of the current sequence of the boot devices

DeviceName Device Number ShortForm IsActive

USB Storage Device 14 usbdev Active

Diskette Drive 12 floppy Active

Internal HDD 13 hdd Active

CD/DVD/CD-RW Drive 15 cdrom Active

Onboard NIC 16 embnic Active

Then, to set the Internal HDD as first, USB Storage Device as second, and Onboard NIC as third; provide BootSequence as 13, 14, 16.

NOTE: The device numbers that are not mentioned will be moved down the 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 based on the device number.

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

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