Hi I was recently asked to setup a Windows 7 image in SCCM for the new Dell XPS 13 Ultrabook laptops. These don't come with a built in NIC so we had to buy a ethernet dongle to connect to the network. I am trying to boot to this USB device via PXE but I dont see the option to boot from the USB device (its not listed). In the bios I did change the boot order to have USB on the top of the list. It doesnt even see it plugged in, the light on the dongle is not lit up. I was able to create a boot disk (WinPE created by SCCM 2007) on a USB stick. This is the only way I have been able to successfully connect to the sccm infrastructure and image my machine successfully. On the laptop, the right port is USB 3.0 and I had to add some extra drivers to my boot image. I really need the ablility to PXE boot this laptop since this is our current process for imaging. Does anyone have any advice? Thanks

You have to check with the vendor of the Ethernet dongle so that have the ability to do pxe-boot.

You can only PXE-boot from a NIC that the BIOS recognizes. Your USB Ethernet has to show up on the BIOS as a boot option. I don't have a Dell XPS 13, so I'm not sure if it supports booting from USB Ethernet. My suggestion is for you to try the following: 1. turn off the notebook. 2. plug-in the USB Ethernet. 3. connect an Ethernet cable and make sure that it is on a network that has access to the PXE server 4. turn-on the machine and see if the PXE boot option shows-up on the BIOS If that does not work, you would have to contact Dell.
