QCCS, You are correct, the 39MB one is the Utility Partition. The 2GB one is a OEM partition. These partitions are created by using your Dell utilities to install the OS, such as using the USC/Lifecycle Controller or a SMTD (Systems Mgmt Tools and Docs) ISO. You can simply delete them and then boot to the 2012 media to install the OS and it won't create the additional partitions. Let me know how it goes.
I bought a new PowerEdge R420 and it's set up with a RAID 50. I went to install Windows Server 2012 and noticed that the virtual disk is already partitioned into a 39 MB, a 2 GB partition and the remainder in a third partition. From what I've read, the 39 MB partition has Dell utilities that you can access during POST, and I'm not sure what the 2 GB partition is. If I want to wipe out this virtual disk and create a RAID 10 array instead, will I be able to get these partitions back? Does it matter? Thanks.
