I'm trying to pxe boot a couple PCs in UEFI mode. When I attempt this it says Starting pxe over IPv4 and then it quits and boots to the OS. Im trying this on the Asus H81MC and Asus H110M motherboards. Is there a setting I need to change on the DHCP server? The DHCP server is running Windows Server 2012 R2. Also we have no issues with creating/restoring images with legacy BIOS computers.
