Fedora is delivered on one or more CD or DVD ROMs.

The first installation CD-ROM can be directly booted into the installation on most modern systems, and contains the following directory structure (where /mnt/cdrom is the mount point of the CD-ROM):

|---- images -- boot and driver disk images 
|---- isolinux -- files necessary to boot from CD-ROM 
|---- Packages -- binary packages 
|---- repodata -- repository information used by the installation process 
|---- README* -- this file 
|---- RELEASE-NOTES* -- the latest information about this release of Fedora 
---- RPM-GPG-KEY* -- GPG signature for packages from Red Hat

The remaining Installation CD-ROMs are similar to Installation CD-ROM 1, except that only the Packages subdirectory is present.

The directory layout of each source code CD-ROM is as follows:

|---- SRPMS -- source packages 
---- RPM-GPG-KEY -- GPG signature for packages from Red Hat

If you are setting up an installation tree for NFS, FTP, or HTTP installations, you need to copy the RELEASE-NOTES files and all files from the Packages directory on discs 1-5. On Linux and Unix systems, the following process will properly configure the /target/directory on your server (repeat for each disc):

  1. Insert disc
  2. mount /mnt/cdrom
  3. cp -a /mnt/cdrom/Packages /target/directory
  4. cp /mnt/cdrom/RELEASE-NOTES* /target/directory
     cp -a /mnt/cdrom/repodata /target/directory
     (Do this only for disc 1)
  1. umount /mnt/cdrom


Many computers can now automatically boot from CD-ROMs. If you have such a machine (and it is properly configured) you can boot the Fedora CD-ROM directly. After booting, the Fedora installation program will start, and you will be able to install your system from the CD-ROM.

The images/ directory contains the file boot.iso. This file is an ISO image that can be used to boot the Fedora installation program. It is a handy way to start network-based installations without having to use multiple diskettes. To use boot.iso, your computer must be able to boot from its CD-ROM drive, and its BIOS settings must be configured to do so. You must then burn boot.iso onto a recordable/rewriteable CD-ROM.

The ability to use this image file with a USB pen drive depends on the ability of your system's BIOS to boot from a USB device.
