Preparing for operating system deployment

Before deploying Windows operating system on the managed servers, update the WinPE image, create a task sequence, LC boot media

file, and task sequence media bootable ISO file. The steps vary for SCCM and SCVMM console users. Refer the bellow section for more

details. For deploying non-windows operating system remember the points mentioned in Preparing for non-Windows OS deployment

section.

About WinPE image

Windows Preinstallation Environment (WinPE) image is used for deploying operating system. Use an updated WinPE image for deploying

operating system as the WinPE image available from SCCM or SCVMM may not contain the latest drivers. To create a WinPE image

having all the required drivers, update the image using DTK. Ensure that relevant operating system-related driver packs are installed in

Lifecycle Controller.

NOTE: Do not change the filename of boot.wim file.

Providing WIM file for SCCM

Copy the boot.wim file from the following location \\shareip\sms_sitecode\OSD\boot\x64\boot.wim, and then paste it to a

share folder accessible by OMIMSSC.

For example, location of shared path: \\shareip\sharefolder\boot.wim

Providing WIM file for SCVMM

Boot.WimPE base image to be provided for injecting in the latest boot critical Dell drivers from DTK is generated by installing PXE server in

SCVMM.

1. Install and configure Windows Deployment Server (WDS) role on a server, and then add the PXE server to SCVMM.

For information about adding the WDS role on a server, and adding a PXE server to SCVMM, see Provisioning a Hyper-V host or

cluster from bare-metal computers section of Microsoft documentation.

2. Copy the boot.wim file from the PXE server present at the following location C:\RemoteInstall\DCMgr\Boot\Windows

\Images, and then paste it to a share folder accessible by OMIMSSC.

For example, location of shared path: \\shareip\sharefolder\boot.wim

WDS and PXE server is required only for generating the WinPE based boot.in image and not to be used in deployment scenarios.

Extracting DTK drivers

A DTK file contains the necessary firmware versions that are required for servers on which you are deploying the operating systems.

To download DTK driver, launch https://www.dell.com/support/ -> Browse all products -> PowerEdge ->

Select the server type < C Series, Modular, Rack, or Tower> -> Select the server model -> Search

for the keyword DTK and download the required version.

NOTE:

While using the latest version of DTK for creating a WinPE ISO image, use the Dell EMC OpenManage

Deployment Toolkit for Windows file. The Dell EMC OpenManage Deployment Toolkit for Windows file contains the

necessary firmware versions that are required for systems on which you are deploying the operating systems. Use the
