How to use the Fedora Live Image

1. Introduction

A live image is a safe and easy way to test the Fedora operating system on your own familiar hardware. If you enjoy this experience, you can install the live system software to your system's hard drive. The installation can either replace your existing operating system, or co-exist separately on your hard drive. This live image provides you with an experience that is very similar to running Fedora, but there are some important differences. Refer to Section 5, “Advantages of a Live Image” and Section 6, “Disadvantages of a Live Image” for more information.

2. What Should I Do With My Live Image?

Before you use your Live image, read the next section to learn how to maximize your enjoyment of Fedora. You may also want to read Section 4, “Booting” for hints on starting — or booting — from this media. Then insert this media in your computer and boot from it.

3. Suggested Hardware

This live system successfully boots and runs on most computers with 256 MB or more installed system memory, or RAM. Your computer must have the ability to boot from the device holding the live image media. For instance, if the live image is on a CD or DVD, your computer must be able to boot from the CD or DVD drive.

4. Booting

To set up your system to boot from the live media, shut down or hibernate your computer. Power your computer on, and pay attention to the first screens that appear. Look for a prompt that indicates which key to use for either:
The boot menu option is preferable. If no such prompt appears, consult your manufacturer's documentation for your computer system, motherboard, or mainboard for the correct keystroke. On many systems, the required key will be F12, F2, F1, Esc, or Delete.
Most computers normally boot from a hard disk. If you have a Fedora live image on a CD or a DVD, then set the computer to boot from the DVD or CD drive. If you have a Fedora live image on a USB device such as a USB flash drive, set your computer to boot from the USB device.
If you must make changes to the BIOS configuration, record the current boot device selection configuration before you change it. This record allows you to restore the original configuration if necessary.
The BIOS on older computers might have a very limited range of boot options. If your computer can only boot from floppy diskette or hard disk, there is no practical way to boot from the Fedora live image. Sometimes, an updated BIOS is available from the manufacturer of your computer. A BIOS update might offer additional boot menu choices, but requires care to install properly. Consult the manufacturer's documentation for more information.
Unless you choose to install Fedora from the live image to the computer's hard drive (as described in Section 8, “Installing Fedora from the Live Image”) the Fedora live image does not make any permanent changes to the computer on which you run it. If your own computer cannot boot from the live image, you can safely explore the live image on a newer computer to which you have access, without fear of changing that computer.

7. Experimenting with the Live Image

Explore the icons and menus on and around the desktop to find programs that interest you. In addition, you may wish to explore other capabilities.

7.1. Accessing Existing Data

The live system can access existing data stored on:
  • floppy diskettes
  • USB drives
  • disk partitions
You can therefore test how Fedora interacts with your documents, photographs, and multimedia files, and how files created by programs running in the Fedora live environment work when you transfer them to your existing computing environment.

7.2. Making a Backup Copy of Data

You can use the live image to make backup or archival copies of data, if your computer system includes:
  • a CD or DVD burning drive
  • a hard disk with ample free space
Files normally in use by your previous operating system when it is running are not in use in the Live image. Therefore, you can use the live image to copy files that are problematic for backup software in the previous operating system.

8. Installing Fedora from the Live Image

To install Fedora from this live image, select the Install to Hard Disk application on the Desktop. After you install Fedora, you can customize the software and configuration to your liking on a persistent basis. Although the live image itself only offers a small fraction of the software available for Fedora, this limitation no longer applies once you install Fedora to a computer.
The Fedora 12 Installation Quick Start Guide, available from docs.fedoraproject.org, provides step-by-step instructions to use a live image to install Fedora on typical desktop and laptop computers.
