In the installation process of Windows 2008 R2 as a VM in HyperV, the following error may suddenly come up:
“(Load driver) A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.
Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step.”
When I faced this error, I was pretty surprised since I was convinced I had done the installation this way many times.
However, I quickly found out the cause of this error: a corrupted ISO file. The easiest solution for this: download the ISO file again from a trusted source, or find yourself a DVD of Windows 2008, – somewhere – :-) and mount it to the virtual machine.
Now, I only still have to find out how this ISO got corrupted…
