Huh, I guess it is a problem with Windows OS ISOs. I'll test this posted solution[1] when I have some time later this week.

That looks like it would probably work -- it looks a lot like one of the methods I used on Windows --

diskpart

> select disk 2

> clean

> create partition primary

> format fs=fat32 quick

> active

> assign

> exit

mount ISO and drag/drop contents of ISO to drive.

But I think that method stopped working with Win8/10, maybe something to do with UEFI/Secure Boot?

edit: fix formatting
