Introduction

The following is a detailed description of the OS Deployment client process. When booting an OS Deployment client, you have several options available. Which one to choose depends mainly on the environment in which the client is booted.

Stage	Description
Initial Boot	NBP is loaded via PXE. NBP initiates WinPE load What is an NBP? A network boot program (NBP) is the first file downloaded and executed as part of the Pre-Boot Execution Environment (PXE) boot process. The NBP dictates whether the client can boot from the network, whether the client must press F12 to initiate the boot, and which boot image the client will receive. NBPs are both architecture and firmware specific (BIOS or EFI) specific. On BIOS computers (per the PXE specification), the NBP is a 16-bit, real-mode application. As such, you can use the same NBP for both x86-based and x64-based operating systems that have BIOS . Read more about How Network Boot Programs Work
Load WinPE with injected drivers	The Windows PE Boot image is fetched and booted The drives injected in the Boot.wim are activated to allow the OS Deployment Client to use the network and storage devices of the client What is Windows PE? Windows Preinstallation Environment (WinPE) is a minimal operating system with limited services. It is used to install, deploy, and repair Microsoft Windows Operating Systems Windows PE is not designed to be the primary operating system on a computer but is instead used as a standalone preinstallation environment and as an integral component of other setup and recovery technologies.
