I'm flattening a workstation that came pre-loaded with Win x64 and loading Server 2008 R2 x64. There is a recovery partition[System] and an OS partition [primary]. Will the installation of the Server to the Primary partition automatically update the System partition? If not, is it preferable to delete them both, and recreate the Primary. I'm pretty sure in one of these scenarios, the Recovery partition is created by the setup routine.
