Windows Server 2012 Hyper-V can't create VMs

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?

Any ideas.

Thanks,

Dave

As a side note, I just created a Window7 VM on this server. So,the problem seems specific to W2K8R2
You need to create the VM first with no DVD/media in they VM settings.  (Yep none.)
AFTER the VM is created, add the DVD setting and attach the ISO media.

Also, sometimes you have to add the DVD drive but NOT attache the media.  Save.
Then go back and add the media.
Give it a try.

It turned out that I must have had multiple defective ISO files, even though I had success with the same ISO files in the past.

I finally got a VM of Windows 7 Pro and after that, I was able to get VMs using Windows Server 2012, Windows Server 2008R2 and Windows 8.
