The Fedora release includes several live ISO images in addition to the traditional installation images. These ISO images are bootable, and you can burn them to media and use them to try out Fedora. They also include a feature that allows you to install the Live image content to your hard drive for persistence and higher performance.
7.1. Available Images
For a complete list of current spins available, and instructions for using them, refer to:
7.2. Usage Information
To boot from the Live image, insert it into your computer and
restart. To log in and use the desktop environment, enter the
username fedora. Hit
Enter at the password prompt, since there is no
password on this account. The Live images do not automatically
login so users can select a preferred language. After logging in,
if you wish to install the contents of the live image to your hard
drive, click on the Install to Hard Drive
icon on the desktop.

No i586 Support |
|---|---|
The i686 Live images will not boot on an i586 machine. |
7.3. Text Mode Installation
You can do a text mode installation of the Live images using the
liveinst command in the console.
7.4. Direct Installation
You can add liveinst or textinst
as a boot loader option to perform a direct installation without
booting up the live CD/DVD.
7.4.1. USB Booting
Another way to use these Live images is to put them on a USB
stick. To do this, install the livecd-tools
package from the development repository. Then, run the
livecd-iso-to-disk script:
/usr/bin/livecd-iso-to-disk /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition
where you want to put the image.
This is not a destructive process; any data you currently have on your USB stick is preserved.
7.4.2. Live USB Persistence
Work has continued to better integrate the Live images with the
rest of the system, and improve the tools used for building
them. The livecd-creator utility now also
provides an API for building alternative front-ends as well as
tools for other types of images.
The initial work to support persistent changes with a Live image has also landed. The primary use case is booting from a Live image on a USB flash drive and storing changes to that same device. To do this, download the Live image and then run the following command:
livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition
where you want to put the image.
Replace 512 with the desired size in
megabytes of the persistent data, or overlay. The
livecd-iso-to-disk shell script is stored in
the LiveOS directory at
the top level of the CD image. The USB media must have
sufficient free space for the Live image, plus the overlay, plus
any other data to be stored on the media.
7.4.3. Differences From a Regular Fedora Install
The following items are different from a normal Fedora install with the live images.
Live images provide a subset of packages available in the regular DVD image. Both connect to the same repository that has all the packages.
SSH is disabled by default and NetworkManager is enabled by default in the Live images. SSH is disabled because the default username in the Live images does not have any password. Installation to hard disk prompts for creating a new user name and password however. NetworkManager is enabled by default since Live images target desktop users.
Live image installations do not allow any package selection or upgrade capability since they copy entire the filesystem from media to hard disk or USB disks. After the installation is complete and rebooted, packages can be added and removed as desired with
yumor the other software management tools.Live images do not work on
i586architecture.
