https://docs.fedoraproject.org/en-US/Fedora/24/html/Installation_Guide/sect-preparing-boot-media.html says Use the dd utility to write the image. _Make sure you have the right drive!_ # dd if=/path/to/Fedora-Live-Security-x86_64-21.iso of=/dev/sdd as the '#' prompt hints, you need to be root tin order to run this command. It would be better to be explicit, saying something like Use the dd utility to write the image onto the USB drive. You need to be root to do this, hence the example uses `sudo`. _Make sure you have the right drive!_ $ sudo dd if=/path/to/Fedora-Live-Security-x86_64-21.iso of=/dev/sdd
The install guide has been retired, therefore I'm closing this bug. If you would like to report Fedora docs bugs in the future, please use the "bug" icon on the top right of the affected page, it will take you directly to the appropriate issue tracker.
