If it's a Hybrid ISO, you can do it with Windows dd.exe port.

http://www.chrysocome.net/dd

http://www.chrysocome.net/downloads/dd-0.6bet...

Ubuntu was doing something like this too. At one time, they
had USB_Creator_GTK, which prepared some structures on a USB
stick so that a non-Hybrid ISO could be loaded. That worked
well, and I could use the Ubuntu USB_Creator to load a MINT
iso onto a USB stick.

When the Hybrid ISOs started coming out, they changed the
code in USB_Creator, so it's more or less sector-by-sector dd.
Which negated the ability to take older ISO files and
load then onto a USB stick.

If you have a copy of disktype handy (Cygwin, Win10 bash, etc),
you can also check an ISO to see what it contains in terms
of a partition structure.

    http://disktype.sourceforge.net/

    disktype some.iso

And that will hint as to whether a dd.exe transfer will be
sufficient for the job.

And this does look suitable for dd transfer to a USB stick.
There's everything but the kitchen sink in here ("HFSPLUS" ???) :-)
