Noting that I am evaluating an unregistered ESXI with the following use;
When I enter the settings for a VM;

Select a CD/DVD Drive 1 option as Datastore ISO file, select one, connect, and connect at power on, and then hit save;

When I start the VM, the ISO is not detected at start;

I really want to find a way to boot from an ISO.
How can I make an ISO available within the VM to boot installation media in this situation?
