7.4. Starting the Installation Program

Important — Booting Older Systems from CD or DVD Media

The CD and DVD media include boot catalog entries for both BIOS and UEFI firmware interfaces. This allows you to boot systems based on either firmware interface from the same CD or DVD. However, some systems with very old BIOS implementations cannot handle media with more than one boot catalog entry. These systems will not boot from the CD or DVD and you must instead boot them from USB or PXE.
Note that the boot configurations of UEFI and BIOS differ significantly from each other. Therefore, the installed system must boot using the same firmware that was used during installation. You cannot install the operating system on a system that uses BIOS and then boot this installation on a system that uses UEFI.
To start, first make sure that you have all necessary resources for the installation. If you have already read through Chapter 4, Steps to Get You Started, and followed the instructions, you should be ready to start the installation process. When you have verified that you are ready to begin, boot the installation program using the Fedora DVD or CD-ROM #1 or any boot media that you have created.

7.4.1. Booting the Installation Program on x86, AMD64, and Intel® 64 Systems

You can boot the installation program using any one of the following media (depending upon what your system can support):
  • Fedora DVD/CD-ROM — Your machine supports a bootable DVD/CD-ROM drive and you have the Fedora CD-ROM set or DVD.
  • Boot CD-ROM — Your machine supports a bootable CD-ROM drive and you want to perform network or hard drive installation.
  • USB pen drive — Your machine supports booting from a USB device.
  • PXE boot via network — Your machine supports booting from the network. This is an advanced installation path. Refer to Chapter 11, Setting Up an Installation Server for additional information on this method.
To create a boot CD-ROM or to prepare your USB pen drive for installation, refer to Section 4.5.1, “Alternative Boot Methods”.
Insert the boot media and reboot the system.
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.
After a short delay, a screen containing boot options appears.
As you boot the installation program, be aware of two issues:
  • Once the boot: prompt appears, the installation program automatically begins if you take no action within the first minute. To disable this feature, press one of the help screen function keys.
  • If you press a help screen function key, there is a slight delay while the help screen is read from the boot media.
Normally, you only need to press Enter to boot. Be sure to watch the boot messages to review if the Linux kernel detects your hardware. If your hardware is properly detected, continue to the next section. If it does not properly detect your hardware, you may need to restart the installation and use one of the boot options provided in Chapter 9, Boot Options.
