Same problem, I use rufus
...just select this in Rufus (it will pup-up when you start to copy):
View attachment 5253
...and it's not suitable either to use any 3rd part crappy usb-boot-copy-util, that might include malware (I don't trust the alternatives and don't have time to investigate)......so yes, Rufus seem to be the right choice
And yes it does seem to work using the above option.
Why are you making an ISO image, that's not supported by Rufus?
VMware can do it, Debian can do it, MS can do it......etc.etc.etc......
...or is it a way of making extra money (are you supported by the alternatives)?

Arg a small mistake can have a huge impact.you should use the full USB device as output, not the first partition..
