In ConfigMgr 2007 R2 there can be created Task Sequence Media. This is extremely useful when PXE boot is not available, or not allowed, and an image must be deployed. Default there will be jobs for Stand-alone media (used for offline devices), Bootable media (used for deployment) & Capture media (used for capture a reference machine). With ConfigMgr R3 there is even more functionality available in the Task Sequence Media wizard. Then there will be a job added for Prestaged Media (used for re-deployment).
