With Fedora 25, the Fedora Media Writer tool will be the primary download option for users that want to make their own bootable USB of the Linux distribution.
“Fedora Media Writer is a multiplatform tool which allows anyone to easily and quickly download installation ISO images and use them to create a bootable USB drive,” the Fedora 25 release notes states. “This saves you the effort of manually downloading an ISO image, verifying its checksum, and using dd or similar to write the image to an USB drive.”
