I am trying to test Server 2008 R2 by installing it on a virtual machine running under Hyper-V on Server 2008 R1. Unfortunately, every time I try to install it from the .ISO image, I get a prompt to insert a driver disk. I have tried this on three separate Hyper-V servers with the same result on each one. Is there a driver disk I am somehow missing? According to Microsoft, running a Server 2008 R2 guest is supported ( ). Has anyone else run into this problem? How did you get around it?

You may wish to advise your VM settings. How are you connecting the VHD? – Wayne Sep 22 '09 at 0:14

The .ISO was bad. The hash code did not match the one posted on the Microsoft site. I was able to dig up another .ISO on our network that worked like a charm

When we're moving big ISO images around, this happens a lot more often than we would like to think. Cosmic rays are out to get you! – Skyhawk Feb 4 '12 at 2:50
