If you have an operating system in the form of an .ISO file you may now want to burn it to a USB to run it as a live operating system or even to install it on a computer. This is very easily accomplished today with UNetbootin


Just download and install it (Mac, Windows, Linux) and you can burn your .ISO disk image (or .IMG, etc) to your desired media. This is my preferred method for users who feel like they have need a quick way to set up a USB installer for their operating systems.
