Chapter 5. Beginning the Installation

5.5. Graphical and Text Interfaces
To start the installation program from minimal boot media, a Live image, or the distribution DVD, follow this procedure:
  1. Power off your computer system.
  2. Disconnect any external FireWire or USB disks that you do not need for installation. Refer to Section 6.18.1.3, “FireWire and USB Disks” for more information.
  3. Insert the media in your computer and turn it on.
You might need to press a specific key or combination of keys to boot from the media. On most computers, a message appears briefly on the screen very soon after you turn on the computer. Typically, it is worded something like Press F10 to select boot device, although the specific wording and the key that you must press varies widely from computer to computer. Consult the documentation for your computer or motherboard, or seek support from the hardware manufacturer or vendor. On Apple computers, the C key boots the system from the DVD drive. On older Apple hardware you might need to press Cmd+Opt+Shift+Del to boot from the DVD drive.
If your computer does not allow you to select a boot device as it starts up, you might need to configure your system's Basic Input/Output System (BIOS) to boot from the media.
To change your BIOS settings on an x86, AMD64, or Intel® 64 system, watch the instructions provided on your display when your computer first boots. A line of text appears, telling you which key to press to enter the BIOS settings.
Once you have entered your BIOS setup program, find the section where you can alter your boot sequence. The default is often C, A or A, C (depending on whether you boot from your hard drive [C] or a diskette drive [A]). Change this sequence so that the CD-ROM is first in your boot order and that C or A (whichever is your typical boot default) is second. This instructs the computer to first look at the CD-ROM drive for bootable media; if it does not find bootable media on the CD-ROM drive, it then checks your hard drive or diskette drive.
Save your changes before exiting the BIOS. For more information, refer to the documentation that came with your system.

Aborting the Installation

To abort the installation, either press Ctrl +Alt+Del or power off your computer with the power switch. You may abort the installation process without consequence at any time prior to selecting Write changes to disk on the Write partitioning to disk screen. Fedora makes no permanent changes to your computer until that point. Please be aware that stopping the installation after partitioning has begun can leave your computer unusable.

5.1. The Boot Menu

The boot media displays a graphical boot menu with several options. If no key is hit within 60 seconds, the default boot option runs. To choose the default, either wait for the timer to run out or hit Enter on the keyboard. To select a different option than the default, use the arrow keys on your keyboard, and hit Enter when the correct option is highlighted. If you want to customize the boot options for a particular option, hit the Tab key.

Using Boot Options

For a listing and explanation of common boot options, refer to Chapter 8, Boot Options.
When using Fedora Live media, press any key during the initial boot countdown to bring up the Boot Options menu. The boot options include:
  • Boot
    This option is the default. If you select this option, only the kernel and startup programs load into memory. This option takes less time to load. As you use programs, they are loaded from the disc, which takes more time. This mode can be used on machines with less total memory.
  • Verify and Boot
    This option lets you verify the disc before you run the Live CD environment. Refer to Section 5.3, “Verifying Media” for more information on the verification process.
  • Memory Test
    This option runs an exhaustive test on the memory on your system. For more information, refer to Section 8.6.1, “Loading the Memory (RAM) Testing Mode”.
  • Boot from local drive
    This option boots the system from the first installed disk. If you booted this disc accidentally, use this option to boot from the hard disk immediately without starting the installer.
If you boot the DVD, rescue CD, or minimal boot media, the boot menu options include:
  • Install or upgrade an existing system
    This option is the default. Choose this option to install Fedora onto your computer system using the graphical installation program.
  • Install system with basic video driver
    This option allows you to install Fedora in graphical mode even if the installation program is unable to load the correct driver for your video card. If your screen appears distorted or goes blank when using the the Install or upgrade an existing system option, restart your computer and try this option instead.
  • Rescue installed system
    Choose this option to repair a problem with your installed Fedora system that prevents you from booting normally. Although Fedora is an exceptionally stable computing platform, it is still possible for occasional problems to occur that prevent booting. The rescue environment contains utility programs that allow you fix a wide variety of these problems.
