This is the easiest way to "download" or mount the ISO within a running VM. Start your Virtual Machine (Windows, Linux, or macOS). Go to the top menu bar and click on .
Downloading the ISO is the first conscious act of accepting this bargain. It is a ritual that says: "I trust my hypervisor enough to let the guest touch the host more intimately."
