Create a Data Image Using DISM

Updated: October 20, 2013

Applies To: Windows 8, Windows 8.1, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2

To add applications, files, and other resources to Windows® during an installation, you can create a data image. By using the Deployment Image Servicing and Management (DISM) tool, you can create additional Windows image (.wim) files that contain only files and applications that you intend to copy to the Windows installation.

Data images enable you to add:

  • Applications, files, scripts, and other resources to Windows during an installation.

  • Files, resources, and other data to a partition other than the operating system partition.

noteNote
Data images must be used only to add new files to a Windows installation. Do not use data images to replace existing Windows files. Overwriting operating system data is unsupported.

Previous methods of transferring data to a Windows installation required the use of $OEM$ folders. These folder structures are still supported, but data images provide an easier and more efficient means of transferring additional data to Windows.

In unattended installations, the Windows image to install is specified by the OSImage setting in the Microsoft-Windows-Setup component. You can add one or more DataImage settings in the Microsoft-Windows-Setup component that represent additional data images that you add to the system. For more information, see the Windows® Unattended Setup Reference.

  1. Locate the data that you will create a data image for.

  2. Open a command prompt as an administrator, or boot the computer to Windows PE to open the Windows PE command prompt.

  3. Use DISM to compress your data files to a .wim file. For example:

    Dism /Capture-Image /ImageFile:c:\data\myData.wim /CaptureDir:C:\data\dataFiles /Name:MyData
    

    In this example, everything under the C:\Data\DataFiles directory is added to the .wim file and the .wim file is given the label "MyData". All files and folders under C:\Data\DataFiles are extracted to the root of the drive specified in the answer file.

    For more information about how to use DISM, see DISM Image Management Command-Line Options.

  4. Copy the data image to an available location such as another partition or a network share during Windows Setup.

  1. Use Windows System Image Manager (Windows SIM) to create an answer file that contains the path to the data image to install and the location for the installation.

  2. Add the Microsoft-Windows-Setup\DataImage settings to the appropriate configuration pass for your environment. For example: windowsPE.

  3. Save the answer file and close Windows SIM.

    The answer file must resemble the following example:

       <settings pass="windowsPE">
          <component name="Microsoft-Windows-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
             <ImageInstall>
                <DataImage wcm:action="add">
                   <InstallTo>
                      <DiskID>0</DiskID>
                      <PartitionID>1</PartitionID>
                   </InstallTo>
                   <InstallFrom>
                      <Credentials>
                         <Domain>Fabrikam</Domain>
                         <Username>MyUsername</Username>
                         <Password>MyPassword</Password>
                      </Credentials>
                   <Path>\\networkshare\share\MyData.wim</Path>
                   </InstallFrom>
                      <Order>1</Order>
                </DataImage>
             </ImageInstall>
          </component>
       </settings>
    
  4. Run Setup.exe, specifying the location of the answer file. For example:

    setup /unattend:C:\unattend.xml
    

All the files and folders specified in the data image are extracted to the root of the drive during installation. Executable files and scripts are not run when the data image is applied; they are only copied to the drive. You can use FirstLogonCommands to specify commands to run the first time a user logs on to the computer. For more information about FirstLogonCommands, see the Windows® Unattended Setup Reference.
