5. Preparing a USB flash drive as an installation source

Ensure your USB media has sufficient space

Your USB media will need free space equal to the size of the ISO you obtained in Section 2.2, “Choosing the ISO Files”. For example, a 2.2GB DVD ISO will need 2.2GB of free space on the USB drive, but having slightly more free space on the drive is ideal.

Unusual USB Media

In a few cases with oddly formatted or partitioned USB media, image writing may fail.

5.1. Making Fedora USB Media on a Windows Operating System

Note — This Method Is Not Destructive

This method is not destructive, so existing data on the media is not harmed. Nevertheless, it is always a good idea to back up important data before performing sensitive disk operations.
The most straightforward way to place a Fedora image on USB media using a Windows operating system is to transfer the Fedora live image to the USB device with the LiveUSB Creator tool.
Note that the dd tool discussed in Section 5.2, “Making Fedora USB Media in UNIX, Linux, and Similar Operating Systems” is also available for Windows. Follow the instructions in that section to use an implementation of dd for Windows operating systems. The instructions in this section assume that you will use LiveUSB Creator.
  1. Download the LiveUSB Creator program for Windows from
  2. LiveUSB Creator can create live USB media either from an image file that you downloaded previously, as described in Section 2.2, “Choosing the ISO Files”, or it can download an image file from the Internet. Either:
    • click the Browse button under the Use existing LiveCD label, browse to the location where you previously downloaded a Fedora Live ISO file, and select that file.
    • select a Fedora Live ISO file from the drop-down menu that LiveUSB Creator presents under the Download Fedora label. Note that image files are large and that it is probably impractical to use LiveUSB Creator to download an image file if you do not have a broadband connection to the Internet.
  3. Click Create Live USB.
