@EZY4 I think we both have different problems.
I would suggest that you open a new thread on this.

As a tip: Install VirtualBox + ExtensionPack and set up the network boot only.
VirtualBox has iPXE, which gives you more information.

Furthermore you can use wireshark to check what exactly your machine receives from the dhcp-server.

@george1421 Good to know. Thanks for the information and help!
