Using a Disk Image with a Virtual Optical Drive
While working in Windows, you can mount a disk image to the virtual Windows DVD drive as if it were a DVD inside a real drive. To do so:
In Windows Explorer, open Computer or This PC, right-click the DVD drive icon and choose Select disk image.
Locate the disk image you want to use and click Open.
Note: This functionality is available only for Windows with Parallels Tools installed.
