Unifi PXE Boot setup cannot be any simpler.
In this video we will go over in general what is pxe booting, how does the process flow between the client, dhcp server and finally - the PXE server.

we will demonstrate how a client without proper dhcp configuration will not be able to reach and communicate with a PXE server, but once we configure our DHCP server, in this case, unifi based DHCP server, the client gets its DHCP lease and all other relevant DHCP options (66 + 67), the client is able to power on, get a dhcp, get all related DHCP options, contact the PXE server and start communicating with it successfully.

All we need to do in order to allow the PXE process to work is:
1. Have our PXE server ip address
2. Have our PXE boot file path ready
3. Have our PXE server up and running
4. Make sure firewall rules aren't blocking the communication
5. Client is PXE capable (not all computers support PXE)
