3.4. Preparing Boot Media

Fedora images are Hybrid ISOs and can be used to create installation media with both optical and USB disks, for booting on both BIOS and UEFI systems.

Fedora Media Writer and Universal USB Creators

Fedora Media Writer has been improved and is now the default way to make bootable media. 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). While use of Fedora Media Writer is strongly encouraged, other USB media creation software can work as well.
Some of the new additions to Fedora Media Writer are that Fedora Workstation and Server are the first choices on the main screen. However more choices are available if you select the button below "Custom OS". Options like Fedora Spins will appear. Fedora Spins such as XFCE and Mate will be selectable.
Universal USB creation tools such as Unetbootin are a historically popular way to create USB installers from ISOs intended for optical media. They typically function by creating a filesystem on the USB drive, extracting files from the image, and writing syslinux bootloader to the device.
These methods circumvent the boot-loader configuration built into Fedora images, which are pre-partitioned and designed to boot on UEFI systems with SecureBoot enabled as well as BIOS systems. They do not produce a consistent result with Fedora's images, especially for use with UEFI systems.
Utilities that use a direct write method, and do not modify the Fedora image, will produce the most consistently successful results.

Be sure you choose the right device!

Most media creation methods in this section are destructive. Ensure you do not need any data on the USB stick, and double check you have chosen the correct device before continuing.

  3. 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
Procedure 3.8. Creating a Boot CD or DVD
In addition to creating a bootable USB flash drive, you can also use the provided ISO images to create bootable optical media (a CD or DVD). This approach may be necessary when installing Fedora on an older system which can not boot from USB.

Note

The exact steps you need to take to burn a bootable CD or DVD from an ISO image will vary depending on what disc burning software you use. This procedure only offers a general overview.
  1. Insert a blank CD or DVD into your system's CD or DVD burner.
  2. Open your system's burning software - for example, Brasero on Fedora systems with GNOME desktop environment, or Nero on Windows systems. In the software's main menu, find an option which lets you burn an ISO image to a disc. For example, in Brasero, this option is Burn image in the main menu on the left side of the window.
  3. When prompted, select the ISO image of Fedora to be burned, and the CD or DVD burner with a blank disc inside (if you have more than one drive).
  4. Confirm your selection, and wait for the disc to be burned.
