Not sure why the downvotes for you. I just did this last week and expected to have to jump through a bunch of hoops and download some software that would burn a bootable image to a usb. Nope just format it as NTFS and copy paste the files from the iso.
Although now this is even easier if you commonly are installing a new OS. But for the typical enthusiast that installs a new OS every couple years this solution is overkill.
