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 C.
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. You can then deploy the wim file only if the capacity of operating system drive is greater than 25 GB.
You must create cmd scripts execute-DEW-script.cmd and Task-sequence-dew-script.ps1 before you create a task
sequence to deploy Windows reference image.
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:
For better performance during imaging, Dell Technologies recommends that the total size of the wim file and the
used space is 1 GB less than the size of drive C.
