5.4.8. Installation Destination

The Installation Destination screen allows you to configure storage options - namely, which disks will be used as the installation target for your Fedora installation. At least one disk must always be selected for the installation to proceed.
For information about the theory and concepts behind disk partitioning in Linux, see Section, “Recommended Partitioning Scheme”.


If you plan to use a disk which already contains some data - for example, if you want to shrink an existing Microsoft Windows partition and install Fedora as a second system or if you are upgrading a previous release of Fedora, make sure to back up any important data first. Manipulating partitions always carries a risk - if the process is interrupted or fails for any reason (installer error, hardware failure, power outage, etc.), any data already on the disk may become impossible to recover.
Installation Destination
The Installation Destination screen. There are two local standard disks available, but none are selected; therefore the options at the bottom of the screen (automatic/manual partitioning, encryption, etc.) are grayed out.
Figure 5.12. Installation Destination

In the top part of the screen, all locally available storage devices (SATA, IDE and SCSI hard drives, USB flash drives, etc.) are displayed in the Local Standard Disks section. Local disks are detected when the installer starts - any storage devices connected after the installation has started will not be shown.
If you need to configure additional local storage devices, select I will configure partitioning and press Done to move to Section 5.4.10, “Manual Partitioning”. Then, connect any new hard drives you want to make available during the installation, and press the button marked by a circular arrow in the set of controls below the list of mount points on the left side of the screen. In the dialog window that opens, press Rescan Disks and wait until the scanning process completes. Then, press OK to return to Section 5.4.8, “Installation Destination”; all detected disks including any new ones will be displayed in the Local Standard Disks section.
The Specialized & Network Disks section below shows advanced network storage (such as iSCSI and FCoE disks) currently configured. When you first open this screen, no such devices will be displayed because they can not be automatically detected; to search for network storage devices Add a disk button and proceed with Section 5.4.9, “Installation Destination - Specialized & Network Disks”. Any network storage you configure will then show up in the Specialized & Network Disks the same way local disks are shown above.
All storage devices which will be used to install Fedora have a black circle icon with a white check mark on them. Disks not marked by this icon will not be used during the installation - they will be ignored if you choose automatic partitioning, and they will not be available in manual partitioning.


USB storage devices such as flash drives and external disks will be shown in the Local Standard Disks as well, and they will be available for selection the same way internal hard drives are. Make sure to not select any removable storage as installation targets unless you really want to do so. If you accidentally use a removable drive to install Fedora and then unplug it, your system will likely become unusable.
Unselected and Selected Disk
Disk selection in the Installation Destination screen. Two disks are displayed; only the one on the right side will be used, because it is the only one with a check mark symbol.
Figure 5.13. Unselected and Selected Disk

After you select all disks you want to install Fedora, select one of the two options in the Other Storage Options section:
Additionally, you can select Encrypt my data; this will encrypt all partitions except the ones needed to boot the system (such as /boot) using Linux Unified Key Setup (LUKS). Encrypting your hard drive is recommended. For detailed information about LUKS encryption, see the Fedora Security Guide, available at


If you lose the LUKS passphrase, any encrypted partitions and the data on them will become completely inaccessible. There is no way to recover a lost passphrase. However, if you perform a Kickstart installation, you can save encryption passphrases and create backup encryption passphrases during the installation. See Chapter 9, Automating the Installation with Kickstart for information about Kickstart installations.
To control which one of your selected storage devices will contain the boot loader, click the Full disk summary and bootloader link in the bottom left corner of the screen, and follow the instructions in Section, “Boot Loader Installation”. Note that while in most cases it is sufficient to leave the boot loader in the default location, some configurations (for example, systems which require chain loading from another boot loader) will require the boot drive to be specified manually.
After you select storage devices, choose between automatic and manual partitioning, configure encryption and boot loader location, press Done in the top left corner of the screen. Then, depending on your settings, the following will happen: Boot Loader Installation

Fedora uses GRUB2 (GRand Unified Bootloader version 2) as its boot loader. The boot loader is the first program that runs when the computer starts and is responsible for loading and transferring control to an operating system. GRUB2 can boot any compatible operating system (including Microsoft Windows) and can also use chain loading to transfer control to other boot loaders for unsupported operating systems.


Installing GRUB2 may overwrite your existing boot loader.
If you have other operating systems already installed, the Fedora installer will attempt to automatically detect and configure the boot loader to start them. You can manually configure any additional operating systems after you finish the installation, if they are not detected properly. For instructions on editing GRUB2 configuration, see the Fedora System Administrator's Guide, available at
If you are installing Fedora system with more than one disk, you may want to manually specify where the bootloader should be installed. Click the Full disk summary and bootloader link at the bottom of the Installation Destination screen. The Selected Disks dialog will appear. The bootloader will be installed on the device of your choice, or on a UEFI system, the EFI system partition will be created on that device during guided partitioning.
Boot Device Selection
The Selected Disks dialog, displaying all disks selected as installation targets and allowing you to set one of them as a boot device. The boot loader will be installed onto that device.
Figure 5.14. Boot Device Selection

In the Boot column, a "tick" icon marks one of the devices as the intended boot device. To change the boot device, select a device from the list and click the Set as Boot Device button to install the boot loader there instead. Only one device can be set as the boot device.
To decline installation of a new boot loader, select the device currently marked for boot and click the Do not install bootloader button. This will remove the tick and ensure GRUB2 is not installed on any device.


If you choose not to install a boot loader for any reason, you will not be able to boot the system directly, and you must use another boot method, such as a stand-alone commercial boot loader application. Use this option only if you are sure you have another way to boot your system.
The boot loader may also require a special partition to be created, depending on whether your system uses BIOS or UEFI firmware and also depending on whether the boot drive has a GUID Partition Table (GPT) or a Master Boot Record (MBR, also known as msdos) label. If you use automatic partitioning, the installer will create this partition if needed. For details, see Section, “Recommended Partitioning Scheme”.
