2. Select Virtual CD/DVD-ROM
3. Select Device [?:]

Is there any drive letter assigned to the virtual drive? If not, check in device manager if any drivers are installed for the virtual device, and in case there're none, install via cdrom.inf supplied by OS (point to cdrom.inf in hidden Windows\Inf folder).
