How to Manage Boot Images in Configuration Manager

In the Configuration Manager console, click Software Library.

In the Software Library workspace, expand Operating Systems, and then click Boot Images.

On the Home tab, in the Create group, click Add Boot Image to start the Add Boot Image Wizard.

On the Data Source page, specify the following options, and then click Next.

- In the **Path** box, specify the path to the boot image WIM file. Click **Browse** to locate a specific boot image file.

  The specified path must be a valid network path in the UNC format. For example: **\\\\servername\\\<sharename\>\\bootimage.wim**.

- Select the required boot image from the **Boot Image** drop-down list. If the WIM file contains multiple boot images, each image is listed.

On the General page, specify the following options, and then click Next.

- In the **Name** box, specify a unique name for the boot image.

- In the **Version** box, specify a version number for the boot image.

- In the **Comment** box, specify a brief description of how the boot image is used.

Complete the wizard.

In the Boot Images node, select the boot image objects that you want to deploy.

On the Home tab, in the Deployment group, click Distribute Content to start the Distribute Content Wizard.

On the General page, in the Content box, select the boot image that you want to distribute, and then click Next.

On the Content Destination page, click Add, and then select Collections, Distribution Point, or Distribution Point Group to display a list of the available collections that are associated with distribution point groups, distribution points, and distribution point groups.

Select the collections, distribution points, and distribution point groups where the boot image will be distributed, and then click OK.

Click Next.

Complete the wizard.

In the Configuration Manager console, click Software Library.

In the Software Library workspace, expand Operating Systems, and then click Boot Images.

Select the boot image that you want to modify.

On the Home tab, in the Properties group, click Properties to open the Properties dialog box for the boot image.

Set any of the following settings to change the behavior of the boot image:

- On the **Images** tab, if you have changed the properties of the boot image by using an external tool, click **Reload**.

- On the **Drivers** tab, add the Windows device drivers that are required to boot Windows PE. Consider the following when you add device drivers:

    - As a best practice, add only NIC and Mass Storage Drivers to the boot image unless there are requirements for other drivers to be part of Windows PE.

    - Because Windows PE already comes with many drivers built in, add only NIC and Mass Storage Drivers that are not supplied by Windows PE.

    - Make sure that the drivers that you add to the boot image are Windows 7 or Windows Server 2008 R2 drivers, and that they match the architecture of the boot image.

    - Beginning with System Center 2012 Configuration Manager SP2:

      **Hide drivers that do not match the architecture of the boot image**: Use this setting to only display only drivers for the architecture of the boot image. The architecture is based on the architecture reported in the .INF from the manufacturer.

    - Beginning with System Center 2012 Configuration Manager SP2:

      **Hide drivers that are not in a storage or network class (for boot images)**: Use this setting to only display storage and network drivers, and hide other drivers that are not typically needed for boot images, such as a video driver or modem driver.

    - Beginning with System Center 2012 Configuration Manager SP2:

      **Hide drivers that are not digitally signed**: Use this setting to hide drivers that are not digitally signed.

- On the **Customization** tab, select any of the following settings:

    - Select the **Enable Prestart Commands** check box to specify a command to run before the task sequence is run. When prestart commands are enabled, you can then specify the command line that is run, whether support files are required to run the command, and the source location of those support files.

      <div class="alert">


      > [!TIP]
      > <P>Add <STRONG>cmd /c</STRONG> to the start of the command line to avoid the need to specify the exact location on the media for the prestart command files.</P>

    - Set the **Windows PE Background** settings to specify whether you want to use the default Windows PE background or a custom background.

    - Select the **Enable command support (testing only)** check box to open a command prompt by using the **F8** key while the boot image is deployed. This is useful for troubleshooting while you are testing your deployment. Using this setting in a production deployment is not advised.

    - For System Center 2012 Configuration Manager SP1 and later:

      Configure the Windows PE scratch space, which is temporary storage (RAM drive) used by Windows PE. For example, when an application is run within Windows PE and needs to write temporary files, Windows PE redirects the files to the scratch space in memory to simulate the presence of a hard disk. By default, Windows PE allocates 32 megabytes (MB) of writeable memory.

- On the **Data Source** tab, update any of the following settings:

    - Set the **Image path** and **Image index** boxes to change the source file of the boot image.

    - Select the **Update distribution points on a schedule** check box to create a schedule for when the boot image package is updated.

    - Select the **Persist content in client cache** check box if you do not want the content of this package to age out of the client cache to make room for other content.

    - Select the **Enable binary differential replication** check box to specify that only changed files are distributed when the boot image package is updated on the distribution point. This setting minimizes the network traffic between sites, especially when the boot image package is large and the changes are relatively small.

    - Select the **Deploy this boot image from the PXE service point** check box if the boot image is used in a PXE deployment.

      <div class="alert">

- On the **Data Access** tab, select any of the following settings:

    - Set the **Package share settings** if you want clients to install the content in this package from the network.

    - Set the **Package update settings** to specify how you want Configuration Manager to disconnect users from the distribution point. Configuration Manager might be unable to update the boot image when users are connected to the distribution point.

- On the **Distribution Settings** tab, select any of the following settings:

    - In the **Distribution priority** list, specify the priority level that you want Configuration Manager to use when multiple packages are distributed to the same distribution point.

    - Select the **Distribute the content for this package to preferred distribution points** check box if you want to enable on-demand content distribution to preferred distribution points. When this setting is enabled, the management point distributes the content to all preferred distribution points when a client requests the content for the package and the content is not available on any preferred distribution points.

      <div class="alert">


      > [!NOTE]

- On the **Content Locations** tab, select the distribution point or distribution point group and perform any of the following actions:

    - Click **Redistribute** to distribute the boot image to the selected distribution point or distribution point group again.

    - Click **Validate** to check the integrity of the boot image package on the selected distribution point or distribution point group.

- For System Center 2012 Configuration Manager SP1 and later:

  On the **Optional Components** tab, specify the components that are added to Windows PE for use with Configuration Manager. For more information about available optional components, see the [Building a Windows PE Image with Optional Components](https://go.microsoft.com/fwlink/p/?linkid=264385) topic in the [Windows 8 documentation library](https://go.microsoft.com/fwlink/p/?linkid=264386).

- On the **Security** tab, select an administrative user and change the operations that they can perform.

After you have configured the properties, click OK.

Verify that the appropriate task sequence resource file (tsres.dll) is in the corresponding language folder on site server before you update the boot image. For example, the English resource file is in the following location: <ConfigMgrInstallationFolder>\OSD\bin\x64\00000409\tsres.dll.

As part of your prestart command, set the SMSTSLanguageFolder environment variable to the appropriate language ID. The language ID must be specified by using decimal and not hexadecimal. For example, to set the language ID to English, you would specify a decimal value of 1033 instead of the hexadecimal value of 00000409 used for the folder name.
