SCCM + Boot Images + WDSNBP + Operating System Deployment (Oh..Yah...)

Hi Guys,

In this post  we will focus on about boot images & OSD Process In SCCM.

So quick questions are 

What are boot images in SCCM?

Boot Images are the image used to boot the machine.

The two types of largely used Boot images

WinPE Boot Images: These are used to boot the machine in to Windows Pre Execution Environment or we can say that Windows Installation Mode.

OS Boot Images: These are the boot images used to boot the machine to load the Operating System.

Boot Images can contain Drivers like storage drivers, network drivers or any drivers you want to have in boot images, you can simply add or inject those drivers.

You can customize the settings of Boot Images or can create your own new Boot Images by integrating MDT with SCCM.

Now How SCCM OSD actually works

OSD is a very cool feature of SCCM. Once you do the configuration for OSD, you are ready to do Operating System Deployments. Apart from Boot Images there are some very important components of OSD

PXE : PXE helps Machines to boot in Windows Installation Mode ( WinPE) when they have  started up in network  boot mode.

WDSNBP (WDS network boot point): WDSNBP contains the network boot program which a small chunk of machine specific code that initiates the download of the actual boot image via TFTP.

Whole OSD Process is

Machine starts up in network installation mode

Gets the IP from DHCP

Gets the PXE boot using WDSNBP (WDS network boot point)

WDSNBP (WDS network boot point) detects the architecture of machine

Responds back to SCCM Server & delivers the appropriate WinPE Boot Images (X86, X64)

Machine boots in to WinPE Environment

Connects to the SCCM Server

Download the OSD files

Connects to Task sequence & start the Execution

Very soon i will post on issues & troubleshooting  with PXE Boot, Boot Images, WDSNBP, DHCP,WDS, OSD

I hope this will be helpful. 

cheers
