With the liveusb-creator tool, you can set up USB media to hold a bootable copy of Fedora. This allows you to run Fedora on a computer without making any changes to the computer's hard drive, as long as the computer is capable of booting from USB media, and is set up to do so.
To create a bootable copy of Fedora on USB media, you will need:
a USB media device with at least 800 MB of free space on it. USB media often comes in the form of flash devices sometimes called pen drives, thumb disks, or keys; or as an externally connected hard disk device. Almost all media of this type is formatted as a vfat file system. You can create bootable USB media on media formatted as ext2, ext3, or vfat.
The Fedora installation will occupy around 800 MB. Beyond this, you might want to allocate space for Fedora to store files such as documents or software installations. These documents and programs will be available to you every time you start a computer with this USB media device, since they are stored on the device itself and not on the computer to which it is attached. This feature is a major advantage of running Fedora from Live USB media rather than from a Live CD.
USB Image Writing is Non-destructive
Existing data on the media is not harmed and there is no need to repartition or reformat your media. However, it is always a good idea to back up important data before performing sensitive disk operations.
Unusual USB media
In a few cases with oddly formatted or partitioned USB media, the image writing may fail.
a copy of the Fedora Live CD or Fedora KDE Live CD, or a connection to the Internet. The liveusb-creator tool copies the files from a Fedora Live CD or Fedora KDE Live CD to create bootable USB media. If you do not have a Fedora Live CD or Fedora KDE Live CD, liveusb-creator can download a CD image from the Internet. However, because this CD image is a very large file, you might find this approach impractical if you do not have a broadband Internet connection.
