NOTE: If any I/O errors occur during image creation, this may indicate a problem with your disc or that your CD/DVD-ROM drive is not functioning properly. Specify a name and location for the image (or leave the default settings) and click Save.

Click File > New Image > Image from 'Win10' (where Win10 is the source name) Select the source from the Disk Utility device list. But please note that upgrade installation media can only be used to upgrade an existing virtual machine (e.g., Windows 7 to Windows 10) - it cannot be used to create a new VM. NOTE: You may use any kind of genuine Windows installation media, full version or upgrade. Open Disk Utility on your Mac (via Launchpad, Spotlight or Finder). Depending on the source type, insert a CD/DVD disc into the CD/DVD-ROM drive or plug-in a USB stick.These instructions apply to both Windows installation media and 3rd-party software disks. I have a disk with software I want to install to Windows virtual machine, but my Mac does not have CD/DVD drive.I have a bootable USB stick (CD/DVD disc) and I want to create an installation image (*.dmg) out of it.
