I have about 5 Win 7 SP1 x64 WIM images that i have placed into a single WIM file using the imagex /export command. I assume this is using single instance storage to perform deduplication of files and replace them with links.
My question is how does MDT 2010 (in SCCM) utilize the multiple WIM images inside the single WIM file?
When i deploy an OS through SCCM with MDT2010 i use the "Apply Operating system from a captured image" selection and select the single WIM package file then select the individual WIM image from within the WIM file. However when the OSD begins to deploy the OS it downloads the entire 30GB WIM file rather than just the 7GB WIM image.
The same thing happens when i try to create stand alone media. Instead of the image being ~7GB its 30GB.
Is this by design? If not am i doing something wrong in my deployment?
