Not wishing to cast doubt needlessly, but I have to wonder how reliable the advice is at http://docs.kali.org, in particular the advice on making a Kali Bootable USB drive at https://forums.kali.org/newthread.php?do=newthread&f=4.
Why? Because the advice is, if you're working from Windows, to use Win32 Disk Imager with the ISO file to create the bootable USB.
What's the problem with this? Win32 Disk Imager works with image files not ISO files. Whoops.
It's not possible to select an ISO file and therefore its not possible for an ISO file and path to appear in the box as shown.

This leads me to wonder if the image shown has been faked, ie not a genuine screen shot. (Note that the slash faces the wrong way).
Apologies in advance if I'm talking out of turn, but some clarity would be helpful.
