Deployment Guide

Prerequisites to capture and deploy an

operating system

•

When capturing an operating system image by using capture media task sequence, ensure that the FODPacks folder is not present in

the C drive. If there is any FODPacks folder, delete the folder.

• When you deploy an operating system image to the client by using a task sequence, the size of the wim file that is captured using the

capture media and the size of the used space of drive C in the reference device put together must be less than the capacity of drive

For example, if the size of the wim file that is captured from reference device is 8 GB, the size of the used space in the drive C is 17

GB, then you can deploy the wim file only if the capacity of operating system drive is greater than 25 GB.

1. Create a text file with name execute-DEW-script and copy the following content to the file:

%Windir%\System32\WindowsPowerShell\v1.0\powershell.exe -command Set-ExecutionPolicy

Unrestricted

%Windir%\System32\WindowsPowerShell\v1.0\powershell.exe "C:\DEW_Temp\Task-sequence-dew-

script.ps1"

2. Save the text file in the SCCM Share DEW folder with name execute-DEW-script.cmd.

3. Create a text file with name Task-sequence-dew-script and copy the following content to the file:

#C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe Set-ExecutionPolicy -

ExecutionPolicy Unrestricted

#Get GUID

$id = Get-WmiObject -Class Win32_Volume |Where-Object {$_.Name -like "C:\DEW\"} | Select-

Object -property "DeviceID"

#Set-Volume -UniqueId $test.DeviceID -NewFileSystemLabel DEW_VOLUME`

#formatting DEW volume

Format-Volume -Path $id.DeviceID -FileSystem NTFS -Force -Full

$service = "DEWSERVICE"

Set-Service -Name $service -StartupType Disabled

New-Item -path 'C:\DEW\DEW_VOLUME' -ItemType Directory

New-Item C:\DEW\DEW_VOLUME\DEW.txt

Set-Content C:\DEW\DEW_VOLUME\DEW.txt 'DEW_PARTITION'

4. Save the text file in the SCCM Share DEW folder with name Task-sequence-dew-script.ps1.

NOTE:

It is recommended that the size of the wim file and the used space put together is 1 GB less than the size of drive C for

better performance during imaging.
