UEFI PXE boot only works with USB flash drive.

UEFI PXE boot doesn’t through network, only with USB flash drive. PXE over IPv4 times out.

@chadman00 What client machines do you have? Does it timeout for different models? Which version of FOG do you use? What is serving DHCP in your setup? Does PXE booting legacy BIOS clients work?

Too many open questions to be able to give an answer!

@Sebastian Roth Our client machines range from Dell Optiplex 7040s to 7060s. It times out for all models, just not working period. Running FOG version 1.5.4. DHCP server is Windows 2012 R2. PXE booting legacy BIOS clients work, and I’ve made the necessary changes according to this:

@chadman00 While I don’t like to jump right into capturing network traffic, I think its going to be the easiest way to understand if you have the filters setup right with dhcp.

place a target computer on the same subnet as your fog server and dhcp server for the best picture of what is going on then follow this tutorial: https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue

Take that pcap and look at it with wireshark. Looks at the OFFER response from your dhcp server. Make sure the boot file name is correct. If you are lost looking at the pcap upload it to a google drive and share it as public and post the link here and one of us will look at it to see if your dhcp server is responding correctly.
