Have you gotten to networking yet (i.e. you could run tcpdump on the server side)? Or are you still stuck with BIOS setting? Are you able to locate PXE Option ROM in BIOS menu, as well as UEFI boot device priority?
Incidentally, I don't think this has anything to do with PC maker (Lenovo or Dell), but as long as its Windows, the video/article is probably useful to you. If your server side hasn't gotten any packet (tcpdump), you probably need to look more closely at the client side setting.
