Always back up your data before performing an upgrade or reinstalling your system, no matter which method you choose.
Always think twice before writing an image to the device. The media creation methods described in this article are destructive. All data on the USB stick are deleted during the process, so make sure you have a back up of the data on the USB stick. Double check that you have selected correct device to write the image to!
[application]*Fedora Media Writer* has been significantly improved and is now the official, tested and supported way to make bootable media. [application]*Fedora Media Writer* supports Linux, Mac, and Windows. It is an easy way to make bootable USB media to install Fedora (or other operating systems). Using [application]*Fedora Media Writer* is strongly encouraged, although other USB media creation software can work as well.
Automatic upgrade using [application]*dnf system upgrade*
