found following for a first step:
1.Loading Windows Recovery / Cmd Prompt via an USB Stick (Windows 7 USB / DVD Download Tool)
2.Entering Command Prompt
a.) Command: Diskpart
b.) Command: List Disk
b.) Command: Select Volume 0
c.) Command: Active = Set Volume Active (bootable)
Then following Commands:
Computer booted and seemed to find MBR and loaded "Preparing Automatic Repair". Then I have the choice of "Continue Loading Win Server 2012 R2" or "Troubleshoot" or "Turn off".
1.) Continue Loading --> It loads something then blank screen and restart. And againg loading "Preparing Automatic Repair"
a) Command Prompt --> Not Possible because no Adminstrator account was found??
b) Startup settings --> This brings up another boot screen, but any choice onds up with loading "Preparing Automatic Repair" or Restart
Did you contact Super Micro* about this? I suggest doing so because the RAID software usually is specific or customized for this board.
It might be possible to reset the member disks to non-RAID and see if it can boot with the SATA controller in RAID mode again; then, rebuild the RAID from one of the existing drives while maintaining the data. I know this is possible in Desktop Chipsets but I am not aware of your Server RAID solution, so you will need to ask Super Micro if such thing is possible with your system.
