3.3. Making Minimal Boot Media

A piece of minimal boot media is a CD, DVD, or USB flash drive that contains the software to boot the system and launch the installation program, but which does not contain the software that must be transferred to the system to create a Fedora installation.
Use minimal boot media:
You can use minimal boot media to start the installation process on 32-bit x86 systems, AMD64 or Intel 64 systems, and POWER systems. The process by which you create minimal boot media for systems of these various types is identical except in the case of AMD64 and Intel 64 systems with UEFI firmware interfaces — refer to Section 3.3.1, “UEFI-based systems”.
To make minimal boot media for 32-bit x86 systems, BIOS-based AMD64 or Intel 64 systems, and POWER systems:
  1. Download the ISO image file named boot.iso that is available at the same location as the images of the Fedora 17 installation DVD — refer to Chapter 2, Obtaining Fedora.
  2. Burn boot.iso to a blank CD or DVD using the same procedure detailed in Section 3.1, “Making an installation DVD” for the installation disc, or transfer the boot.iso file to a USB device with the dd command as detailed in Section 3.2, “Preparing a USB flash drive as an installation source”. As the boot.iso file is only around 200 MB in size, you do not need an especially large USB flash drive.

3.3.1. UEFI-based systems

The Fedora Project does not provide an image to produce minimal boot CDs or DVDs for UEFI-based systems. Use a USB flash drive (as described in this section) to boot the Fedora 17 installer. The full DVD installation image should function as expected.
Use the efidisk.img file in the images/ directory on the Fedora 17 installation DVD to produce a bootable USB flash drive for UEFI-based systems.
  1. Download an ISO image file of the Fedora 17 installation DVD as described in Chapter 2, Obtaining Fedora.
  2. Become root:
    su -
  3. Create a mount point for the ISO image file:
    # mkdir /mnt/dvdiso
  4. Mount the image file:
    # mount DVD.iso /mnt/dvdiso -o loop
    Where DVD.iso is the name of the ISO image file, for example Fedora17-x86_64-DVD.iso.
  5. Transfer efidisk.img from the ISO image file to your USB flash drive:
    # dd if=/mnt/dvdiso/images/efidisk.img of=/dev/device_name
    For example:
    # dd if=/mnt/dvdiso/images/efidisk.img of=/dev/sdc
  6. Unmount the ISO image file:
    # umount /mnt/dvdiso
