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.

BootList — 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. Following are the supported UEFI devices:
- hdd — hard disk
- cdrom — CD-ROM
- hsbhdd — USB hard disk
- usbdev — USB device
- embnicipv4 — embedded NIC IPV4
- embnicipv6 — embedded NIC IPV6
- fibrechannel — Fibre Channel
- Embnic — embedded NIC
- fibrechannelex — FibreEx Channel
- infiniband — Infiniband device
- vendor — vendor device
- i1394 — I1394 device
- i2o — I20 device
- uart — UART device
- lun — LUN device
- vlan — VLAN device
- nvme — NVMe device
- uri — URI device
- ufs — UFS device
- sd — SD device
- bluetooth — Bluetooth device
- wifi — Wi-Fi device
- emmc — eMMC device
Legacy (the default) — To ensure compatibility with operating systems that do not support UEFI. Following are the supported legacy devices:
- floppy — floppy disk
- hdd — hard disk
- cdrom — CD-ROM
- pcmcia — PCMCIA Device
- usbdev — USB Device
- nic — NIC
- usbfloppy — USB floppy disk
- usbhdd — USB hard disk
- usbcdrom — USB CD-ROM
- Embnic — embedded NIC
- usbzip — USB ZIP
- usbdevzip — USB device ZIP
- bev — BEV device
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, shortform, and device number. Then, provide the sequence to change the boot order. For example, see the following table:

Table 1. Example of the current sequence of the boot devicesThe table below describes the 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"

Example: To change the current boot mode to UEFI.

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

Example: To change the boot sequence based on the shortform.

Set-Item -Path DellSmbios:\BootSequence "cdrom,hdd,embnicipv6"
