USB-C Only Laptop - PXE Boot

[StephenPink]

Hey all,

This one's got me stumped - got some new Dell 2-in-1 devices, connected to Dell Docks and they will not show the network PXE boot option... 

 

BIOS is all updated, reset to defaults and then the following settins applied:

 

BIOS
    - Advanced Setup > On

    - Boot Configuration
        ○ Enable PXE Boot Priority: Enabled
            
    - Integrated Devices
        ○ USB/Thunderbolt Configuration:
            § Enable Thunderbolt Boot Support: On

    - Connection
        ○ Enable UEFI Network Stack:
            § IPv6 PXE Boot > Off
        
        ○ HTTP(s) Boot Features:
HTTP(s) Boot > Off

 

 

IPv4 PXE Boot is definitely on, but do not get any boot options appear other than the internal hard disk. Hopefully there's just a setting that's been missed?

Cheers

BIOS is probably not seeing the USB-C connection as a NIC/Adapter. Have you done some google-fu and checked if that device/bios supports PXE booting over USB-C? You would imagine so, if there is no ethernet port..

 

On a wim, just try disable secure boot & see if that makes any difference?

 

We still use MDT for our imaging. When we get a device in with no ethernet port (lik many of the DFE laptops..) , we use a USB > Ethernet adapter & boot into Windows PE via USB to kick off the deployment sequence.

Yeahhh... post-summer brain is a thing! Turns out the Dell UD22 docks DON'T support PXE boot, so have ordered some new USB-C Ethernet adapters that definitely say they DO support PXE boot... 

Thanks!
