An iso is usually a Bootable Installer of an operating system, unless it's a Live Edition of a Linux distro.

You may have a bootable Windows based PE, but it's quicker to mount the ISO and install as below

So you've got one step to create the virtual machine first by

1. Creating an empty virtual machine in Hyper-V.
2. Connect the ISO media
3. BOOT the Virtual Machine (as you would a physical computer)
4, Install (as you would a physical computer)
5. You then have your OS on a VHDX file.

I have two very thorough EE articles on all things Hyper-V:
