I have a curious issue, I am doing an imaging job of 1000 desktops which is done via PxE boot. On first boot I disable secureboot and change the boot order to the IPv4 nic, save changes and reboot. It pixie boots fine and runs through the registration process on the imaging rig, then after reboot it should pxe boot again and begin to deploy the image.
What happens is after it has registered and reboots, it then begins to boot into Windows. When I go back into the BIOS the boot order has changed itself back to the M2.SSD. I can't seem to find an option to turn this off.
