I am trying to install Windows server 2012 on my X9SRA. I am sure that I have specified the correct RAID driver to load. Why do I keep on getting the message "A media driver your computer needs is missing. This coluld be a DVD, USB or Hard disk drives....." when I load the RAID driver?
This issue is related to the Microsoft OS installation media, device or ISO file. Please refer to the below link for possible causes and resolution.
