Preparing for Installation

This chapter describes the steps you need take before you begin the installation. Not every step must be strictly followed - for example, if you plan to use the default installation settings, you do not need to gather system information such as disk device labels/UUIDs or network information such as the system’s IP address. However, you should still go through this chapter, as it also describes the available types of installation media and how to prepare boot media and installation sources.

Upgrade or Install?

If you already have Fedora installed and want to upgrade your installation to the current version, there are two basic ways to do so:

Automatic upgrade using dnf system upgrade: The preferred way to upgrade your system is an automatic upgrade using the dnf system upgrade utility. For information on performing an automatic upgrade, see Fedora Wiki dnf system upgrade.
Manual Reinstallation: You can upgrade to the latest version of Fedora manually instead of relying on dnf system upgrade. This involves booting the installer as if you were performing a clean installation, letting it detect your existing Fedora system, and overwriting the root partition while preserving data on other partitions and volumes. The same process can also be used to reinstall the system, if you need to. For detailed information, see Manual System Upgrade or Reinstallation.

Always back up your data before performing an upgrade or reinstalling your system, no matter which method you choose.

Downloading Boot and Installation Images

The Fedora Project offers different Editions tailored for some specific use cases. Choose the Fedora Edition best for you, or you can build your own by customizing after the installation, or by using a kickstart file as described in Creating a Kickstart File. Kickstart installation requires the netinstall media type, or a direct installation booting method such as PXE; kickstarts are not supported with live images.

Read more about Fedora Workstation, Fedora Cloud, Fedora Server and the available media types in Downloading Fedora.

You can also choose a Fedora Spin featuring favorite alternative desktops or tools for specialized tasks at http://spins.fedoraproject.org.

Verifying the Downloaded Image

Because transmission errors or other problems may corrupt the Fedora image you have downloaded, it is important to verify the file’s integrity. After the images are created, an operation is performed on the file that produces a value called a checksum using a complex mathematical algorithm. The operation is sufficiently complex that any change to the original file will produce a different checksum.

By calculating the image’s checksum on your own computer and comparing it to the original checksum, you can verify the image has not been tampered with or corrupted. The original checksum values are provided at https://fedoraproject.org/verify, and are gpg signed to demonstrate their integrity.

Verifying checksums on Windows systems

Download the Fedora image of your choice from https://fedoraproject.org/get-fedora and the corresponding checksum file from https://fedoraproject.org/verify
Open a powershell session.

Change to the directory containing the downloaded files.

> cd $HOME\Downloads\
> ls

Directory: C:\Users\Pete\Downloads

Mode                LastWriteTime         Length  Name
----                -------------         ------  ----
-a---        11/25/2014  12:39 PM            272  Fedora-Server-21-x86_64-CHECKSUM
-a---        11/25/2014  12:39 PM     2047868928  Fedora-Server-DVD-x86_64-21.iso

Load the resources required to calculate the checksum.

> $image = "Fedora-Server-DVD-x86_64-21.iso"
> $checksum_file = "Fedora-Server-21-x86_64-CHECKSUM"
> $sha256 = New-Object -TypeName System.Security.Cryptography.sha256CryptoServiceProvider
> $expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern $image) -split " ")[0].ToLower()

Calculate the downloaded image’s checksum. This will take a while!

> $download_checksum = [System.BitConverter]::ToString($sha256.ComputeHash([System.IO.File]::ReadAllBytes("$PWD\$image"))).ToLower() -replace '-', ''

Compare the calculated checksum to the expected checksum.

> echo "Download Checksum: $download_checksum"
> echo "Expected Checksum: $expected_checksum"
> if ( $download_checksum -eq "$expected_checksum" ) {
echo "Checksum test passed!"
} else {
echo "Checksum test failed."
}

Verifying checksums on Linux and OSX systems

Download the Fedora image of your choice from https://fedoraproject.org/get-fedora and the corresponding checksum file from https://fedoraproject.org/verify
Open a terminal window, and navigate to the directory with the downloaded files.
```
$ cd ~/Downloads
```
Use the appropriate utility to verify the image checksum.
- For Linux:
  $ sha256sum -c *CHECKSUM
- For OSX:
  $ shasum -a 256 -c *CHECKSUM

Preparing Boot Media

Fedora images are Hybrid ISOs and can be used to create installation media with both optical and USB disks, for booting on both BIOS and UEFI systems.

Fedora Media Writer and Universal USB Creators

Fedora Media Writer has been improved and is now the default way to make bootable media. Fedora Media Writer supports Linux, Mac, and Windows. It is an easy way to make bootable USB media to install Fedora (or other operating systems). While use of Fedora Media Writer is strongly encouraged, other USB media creation software can work as well.

Some of the new additions to Fedora Media Writer are that Fedora Workstation and Server are the first choices on the main screen. However more choices are available if you select the button below "Custom OS". Options like Fedora Spins will appear. Fedora Spins such as XFCE and Mate will be selectable.

Universal USB creation tools such as Unetbootin are a historically popular way to create USB installers from ISOs intended for optical media. They typically function by creating a filesystem on the USB drive, extracting files from the image, and writing syslinux bootloader to the device.

These methods circumvent the boot-loader configuration built into Fedora images, which are pre-partitioned and designed to boot on UEFI systems with SecureBoot enabled as well as BIOS systems. They do not produce a consistent result with Fedora’s images, especially for use with UEFI systems.

Utilities that use a direct write method, and do not modify the Fedora image, will produce the most consistently successful results.

Be sure you choose the right device!

Most media creation methods in this section are destructive. Ensure you do not need any data on the USB stick, and double check you have chosen the correct device before continuing.

Creating USB Media on Windows

Download the latest Windows Installer file from Marin Briza’s github page: https://github.com/MartinBriza/MediaWriter/releases.
Run the installation by double clicking it, and then clicking next through the set-up wizard. The Wizard gives you the options to customize the software’s installation if you choose to.
In Windows 8 and 10, the application will be under "all apps" under F for Fedora Media Writer. Or in Windows 10, you can just type Fedora Media Writer in the search box on the task bar.
Select the Fedora Edition you wish to make a bootable USB drive for.

Creating USB media with GNOME Disks

On a system with GNOME, or with the gnome-disk-utility package installed, open Disks using the system menu.
Click your USB device in the left column.
Click the menu icon in the upper right corner of the window, and choose the Restore Disk Image option.
Navigate to your image file and click Start Restoring. After a few minutes, it will report the process is complete and your installation media will be ready to use.

Creating USB Media on the Linux command line

Open a terminal window and insert the usb drive.

Find the device node assigned to the drive. In the example below, the drive is given sdd.

$ dmesg|tail
[288954.686557] usb 2-1.8: New USB device strings: Mfr=0, Product=1, SerialNumber=2
[288954.686559] usb 2-1.8: Product: USB Storage

Use the dd utility to write the image. Make sure you have the right drive!
```
# dd if=/path/to/Fedora-Live-Security-x86_64-21.iso of=/dev/sdd
```

Creating a Boot CD or DVD

In addition to creating a bootable USB flash drive, you can also use the provided ISO images to create bootable optical media (a CD or DVD). This approach may be necessary when installing Fedora on an older system which can not boot from USB.

The exact steps you need to take to burn a bootable CD or DVD from an ISO image will vary depending on what disc burning software you use. This procedure only offers a general overview.

Insert a blank CD or DVD into your system’s CD or DVD burner.
Open your system’s burning software - for example, Brasero on Fedora systems with GNOME desktop environment, or Nero on Windows systems. In the software’s main menu, find an option which lets you burn an ISO image to a disc. For example, in Brasero, this option is Burn image in the main menu on the left side of the window.
When prompted, select the ISO image of Fedora to be burned, and the CD or DVD burner with a blank disc inside (if you have more than one drive).
Confirm your selection, and wait for the disc to be burned.
