5.2. Preparing for a Hard Drive Installation

Note — Not all file systems supported

Hard drive installations only work from ext2, ext3, ext4, or FAT file systems. You cannot use a hard drive formatted for any other file system as an installation source for Fedora.
To check the file system of a hard drive partition on a Windows operating system, use the Disk Management tool. To check the file system of a hard drive partition on a Linux operating system, use the fdisk tool.

Cannot Install from LVM Partitions

You cannot use ISO files on partitions controlled by LVM (Logical Volume Management).
Use this option to install Fedora on systems without a DVD drive or network connection.
Hard drive installations use an ISO image of the installation DVD. An ISO image is a file that contains an exact copy of the content of a DVD.
With these files present on a hard drive, you can choose Hard drive as the installation source when you boot the installation program (refer to Section 8.1, “Installation Method”).
Ensure that you have boot media available on CD, DVD, or a USB storage device such as a flash drive.
To prepare a hard drive as an installation source, follow these steps:
  1. Obtain an ISO image of the Fedora installation DVD (refer to Chapter 2, Obtaining Fedora). Alternatively, if you have the DVD on physical media, you can create an image of it with the following command on a Linux system:
    dd if=/dev/dvd of=/path_to_image/name_of_image.iso
    where dvd is your DVD drive device, name_of_image is the name you give to the give to the resulting ISO image file, and path_to_image is the path to the location on your system where the resulting ISO image will be stored.
  2. Transfer the ISO image to the hard drive.
    The ISO image must be located on a hard drive that is either internal to the computer on which you will install Fedora, or on a hard drive that is attached to that computer by USB.
  3. Use a SHA256 checksum program to verify that the ISO image that you copied is intact. Many SHA256 checksum programs are available for various operating systems. On a Linux system, run:
    $ sha256sum name_of_image.iso
    where name_of_image is the name of the ISO image file. The SHA256 checksum program displays a string of 64 characters called a hash. Compare this hash to the hash displayed for this particular image on the GPG Keys page on the Fedora Project site at The two hashes should be identical.


The Fedora installation program has the ability to test the integrity of the installation media. It works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. We recommend that you test all installation media before starting the installation process, and before reporting any installation-related bugs (many of the bugs reported are actually due to improperly-burned discs). To use this test, type the following command at the boot: prompt:
