In this blog we are going to explain what is PXE Boot and how to configure PXE in system center

INTRODUCTION

Recently one of our customers requested us to do windows 8 OS deployment for a set of machines. So we are planning to do PXE configuration for OS deployment in the SCCM distribution point. As per the request, we have configured PXE in sccm. I was thinking why can’t I document it so that it would be helpful for newbies. We are going to show how to configure PXE in sccm environment

Enabling PXE in SCCM environment which enable us to deploy operating system in the environment. Enabling PXE will allow us to do PXE Boot helping us to load boot image and selecting the Task Sequence to continue the build.

ABOUT PXE

Pre eXecution Environment, in short called PXE. Pronounced Pixie (as in fairy dust), is a method of having an end computer (client) boot using only its network card.

The device sends out a DHCP broadcast and states that it needs to PXE boot. DHCP server picks up this broadcast and replies with a suggested IP address to use. The server has the information on how to PXE boot, that information is included in its reply. The device then replies to the server and uses the provided address. Then the device contacts the PXE boot server. Then the File is then loaded and launched on the client
