I have installed windows 2012 onto new server, it installs and updates fine. All my drivers are loaded and good to go.
All I am doing is adding in a secondary volume, creating the partitions and settings a drive letter. It all works, but once I restart the server it will not longer boot.
If I disable partition or remove the physical drives it boots fine again.
The primary is Mirrored drives, the secondary partion is 4 drivers in raid 5. Nothing special.
I have tried deleting and recreating the raid (hardware), create the volume as gpt or mbr, same thing. If I boot into command line recovery, I see the partitions in diskpart and can browse the drives.
