3.6. Preparing for a Hard Drive Installation

Note

Hard drive installations only work from ext2, ext3, or FAT file systems. If you have a file system other than those listed here, such as reiserfs, you will not be able to perform a hard drive installation.

Hard drive installations require the use of the ISO (or DVD/CD-ROM) images. An ISO image is a file containing an exact copy of a DVD/CD-ROM image. After placing the required ISO images (the binary Fedora DVD/CD-ROMs) in a directory, choose to install from the hard drive. You can then point the installation program at that directory to perform the installation.

Ensure that you have boot media available on CD, DVD, or a USB storage device such as a flash drive.

To prepare your system for a hard drive installation, you must set the system up in one of the following ways:

Using a set of CD-ROMs, or a DVD — Create ISO image files from each installation CD-ROM, or from the DVD. For each CD-ROM (once for the DVD), execute the following command on a Linux system:
```
dd if=/dev/cdrom of=/tmp/file-name.iso
```
Using ISO images — transfer these images to the system to be installed.
The ISO files must be located on a hard drive that is either internal to the computer, or attached to the machine by USB. In addition the install.img file from within the ISO files must be copied to a directory named images Use this option to install Fedora on computers that are without a network connection or CD/DVD drives.
Verifying that ISO images are intact before you attempt an installation, helps to avoid problems. To verify the ISO images are intact prior to performing an installation, use an md5sum program (many md5sum programs are available for various operating systems). An md5sum program should be available on the same Linux machine as the ISO images.

Note

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 CDs). To use this test, type the following command at the boot: prompt:

linux mediacheck

Additionally, if a file called updates.img exists in the location from which you install, it is used for updates to anaconda, the installation program. Refer to the file install-methods.txt in the anaconda RPM package for detailed information on the various ways to install Fedora, as well as how to apply the installation program updates.

To extract the install.img from the ISO follow the procedure:

  mount -t iso9660 /path/to/Fedora12.iso /mnt/point -o loop,ro
  cp -pr /mnt/point/images /path/images/
  umount /mnt/point

Before you begin installation from a hard drive, check the partition type to ensure that Fedora can read it. To check a partition's file system under Windows, use the Disk Management tool. To check a partition's file system under Linux, use the fdisk utility.

Cannot Install from LVM Partitions

You cannot use ISO files on partitions controlled by LVM (Logical Volume Management).
