Debian 8 asking for DVD

It’s very odd but when I try to run the script on my new Debian 8 VM it asks for the DVD. I suspect I didn’t install something the script needs when I set the VM up. What did I miss?

Is it asking for the DVD or perhaps if you would like to keep your version of grub?

Here is the output from the attempted install…

Media change: please insert the disc labeled

in the drive ‘/media/cdrom/’ and press enter

Got past this one by commenting out the cd-rom in /etc/apt/sources.list Apparently I didn’t set up a mirror when I installed the OS. Mark this one as solved please. I am getting a different error now but will make another post.
