Thanks moderator, the goal of my effort is to Install Windows Server 2012 R2.The reason Windows 10 pro came into this conversation is (Tested with windows 10 pro) and that OS worked on PE R900.  Anyway, I will be trying the iso mentioned by previous group member (Charles). Hopefully it will be able to identify the drivers and install the Server 2012 R2. Keep you all updated of the outcome and thanks for the collaboration.   AJ
Why can't the  R900 Server with Server 2012 cannot recognize the  4 X Micron 128 SSD drive which I installed and created a Virtual Disk 0. The System boots and I press F11 to select boot option. The DVD begins the OS process once I enter "Install" - The message I get is Install the drivers for the CD-/ DVD or USB by clicking "Browse" .  Which drivers are the OS trying to locate at this point ? Is it the hard drive (/micron) because this is not a brand listed on the Dell Spec Data Sheet. ?   Any expert experienced advise and support will be greatly appreciated. Thank you all in advance.    Jaco.
