Windows 7 / Getting Started

Operating Modes

To provide a clear path between legacy RIS functionality and Windows Deployment Services functionality, Windows Deployment Services supports three modes (legacy and mixed modes are available only in Windows Server 2003):

  • Legacy mode This mode uses the Client Installation Wizard (OSChooser) and Riprep (sector-based) images. This mode is compatible with RIS. Moving from RIS-only functionality to legacy mode happens when you install the Windows Deployment Services update on a server running RIS.
  • Mixed mode This mode supports both OSChooser and Windows PE for boot environments and Riprep and ImageX imaging. Moving from legacy mode to mixed mode happens when you configure Windows Deployment Services and add .wim image files to it.
  • Native mode This mode supports only the Windows PE boot environment and .wim image files. The final move to native mode occurs after you have converted all legacy images to the .wim image file format and have disabled the OSChooser functionality.

Your choice of operating mode will depend on which client operating systems you are deploying and your investment into legacy Riprep images. You don't need to abandon your current deployment images; operating in mixed mode allows you to continue to deploy legacy RIS images from OSChooser. It also allows you to deploy new .wim images of Windows 7 using Windows PE.

The mode used by Windows Deployment Services is not a simple selection in a dialog box. Each mode is activated in a specific way. The following sections describe each mode in more detail and how to configure each mode.
