Q. I'm getting DISM errors trying to create my Nano server VHD file. What can I do?

A. If there are errors then you will be directed to a log file that gives more detail on the exact error. Most likely if you get errors you are trying to create on a non Windows Server 2016 box whose DISM does not understand the Nano server parameters. Make sure you use a Windows 10 machine or Windows Server 2016 host to create the Nano server images.
