If the BOCount member is greater than one, then you can use the following commands to change the boot
order.
$SBO = Get-WmiObject -Namespace root/dcim/sysman/biosattributes -Class
SetBootOrder
$NewBO = “UEFI Hard Drive”, “Windows Boot Manager”
$SBO.Set(0,0,0, ”UEFI”, $NewBO.Count, $NewBO)
Remember to use the password parameters as demonstrated in the previous section if a password is already
set.
