Installation Notes

To learn how to install Fedora, refer to either the Fedora Installation Quick Start Guide available from http://docs.fedoraproject.org/installation-quick-start-guide/ or the Fedora Installation Guide available from http://docs.fedoraproject.org/install-guide/.
If you encounter a problem or have a question during installation that is not covered in these release notes, refer to http://www.fedoraproject.org/wiki/FAQ and http://www.fedoraproject.org/wiki/Bugs/Common.

Anaconda is the name of the Fedora installer. This section outlines issues related to Anaconda and installing Fedora 21.

Installation in text mode

We recommend that you use the graphical installer to install Fedora on your computer wherever possible. If you are installing Fedora on a system that lacks a graphical display, consider performing the installation over a VNC connection (see "Chapter 12. Installing Through VNC" in the Fedora 21 Installation Guide). If your system has a graphical display, but graphical installation fails, try booting with the xdriver=vesa option (see "Chapter 9. Boot Options" in the Fedora 11 Installation Guide) or with the 'Install system with basic video driver' option when booting from the Fedora 21 DVD.


Kickstart installations in text mode

Text-mode installations using kickstart are carried out in the same way that they were in previous versions. However, because package selection, advanced partitioning, and bootloader configuration are now automated in text mode, Anaconda cannot prompt users for information that it requires during these steps. Users must ensure that the kickstart file includes the packaging, partitioning, and bootloader configurations. If any of this information is missing, Anaconda will exit with an error message.

Upgrade Notes

Upgrading from Fedora 9 directly to Fedora 21 using yum is not possible, you must upgrade to Fedora 10 first, then upgrade to Fedora 21. See http://fedoraproject.org/wiki/YumUpgradeFaq for more information. You can also use preupgrade to upgrade directly to Fedora 11 using Anaconda, minimizing the system downtime by downloading the packages in advance.

Some modified configuration files will be replaced by their original versions during the upgrade. Your modified versions of these configuration files will be saved as *.rpmsave files in that case.

Boot menu

The boot menu for the Fedora DVD includes a new option: Install system with basic video driver. This option boots the system with the generic vesa driver (using the xdriver=vesa kernel option) and allows you to use Fedora's graphical installation mode even when Anaconda cannot load the correct driver for your video card.

boot.iso Now Works on Systems With UEFI

The fedora installation CDs and DVD provide you with an image file, boot.iso that you can burn to a CD and use to boot a system and start the installation process. Typically, you would do this prior to installing Fedora from a local hard drive or from a location on a network. You can now use the CD produced from the boot.iso image to start installation on a system that uses Unified Extensible Firmware Interface (UEFI). CDs produced from older versions of boot.iso only worked with systems that used Basic Input Output System (BIOS).
