I have a Windows Server 2012 server. It is a Supermicro SuperServer 6037R-73RF with 128GB RAM, Dual Xeon E5-2620 processors and 2TB of SAS RAD 10 using the on-board LSI 2208 controller. I have installed Windows Server 2012 Data Center and all of that went just fine. I enabled the Hyper-V role and that went without error. However, I have been trying to create a Windows Server 2008R2 SP2 virtual machine and I keep getting the error "a required CD/DVD drive device is missing" right after I click on the "Install Now" button.
I researched the error and almost every one that I found on Google referred to having mad install media. However, I have tried using an ISO from Microsoft, a CD a different ISO that I had used several times before for standard W2K8 server installs and I am still getting the same problem. It doesn't seem that the problem is with the install media.
One thing I want to note is that when I installed the Host Server 2102 OS, right after the initial install, I checked device manager and there were no exclamation marks on any of the devices so I didn't run the chipset and device installs form the CD provided with the Supermicro motherboard. Could that cause this kind of issue?
