I have the problem, that I am not able to get a VM on our ESXi 6.0.0 to boot over PXE from our WDS if I choose EFI as start option. If I choose BIOS instead, everything works fine.
When I use EFI I get this screen when starting up:
After that I am presented the Boot Manager and can select EFI Network manualy, then I get the following screen. Nothing happens there. After a few seconds I get back to the Boot Manager where I can select another boot media.
Unfortunately I dont have access to our WDS-Server to view any log, but I will ask for this if I cant solve the problem otherwise. If you need any more information feel free to ask.
