Note that you have to format the USB drive as NTFS.   You can't use dd because the Windows installer won't run from
the DVD disk format when using a USB stick.

I found this in my notes, apparently Sam Sieb suggested it as a method
of writing to a storage device, a flash drive in this case.

You have to specify the USB device as /dev/sdX.   The WoeUSB git link has some examples.
