Chapter 4. Beginning the Installation
![[Note]](./stylesheet-images/note.png) | Aborting the Installation |
|---|---|
To abort the installation process at any time before the Installing Packages screen, either press Ctrl+Alt+Del or power off the computer with the power switch. Fedora makes no changes to your computer until package installation begins. |
4.1. The Boot Menu
The boot media displays a graphical boot menu with several options. If no key is hit within 60 seconds, the default boot option runs. To choose the default, either wait for the timer to run out or hit Enter on the keyboard. To select a different option than the default, use the arrow keys on your keyboard, and hit Enter when the correct option is highlighted. If you want to customize the boot options for a particular option, hit the Tab key.
![[Tip]](./stylesheet-images/tip.png) | Using Boot Options |
|---|---|
For a listing and explanation of common boot options, refer to Appendix A, Boot Options. |
If you boot the Live CD, the options include:
Run from image. This option is the default. If you select this option, only the kernel and startup programs load into memory. This option takes less time to load. As you use programs, they are loaded from the disc, which takes more time. This mode can be used on machines with less total memory.
Run from RAM. If you select this option, the Live CD environment loads entirely into memory. This option takes longer to load, since the entire CD is loaded at one time. As you use programs later, they are loaded directly from memory, which results in a more responsive environment. This mode can only be used on machines with at least 1 GB of RAM.
Verify and run from image. This option lets you verify the disc before you run the Live CD environment. Refer to Section 4.3, “Verifying Media” for more information on the verification process.
If you boot the DVD, rescue CD, or minimal boot media, the boot menu options include:
Install or upgrade an existing system. This option is the default. Choose this option to install Fedora onto your computer system using the graphical installation program.
Install or upgrade an existing system (text mode). Choose this option to install Fedora onto your computer system using the text-based installation program. If your computer system has problems using the graphical installation program, you can install the system with this option. Installing with this option does not prevent you from using a graphical interface on the system once it is installed.
Rescue installed system. Choose this option to repair a problem with your installed Fedora system that prevents you from booting normally. Although Fedora is an exceptionally stable computing platform, it is still possible for occasional problems to occur that prevent booting. The rescue environment contains utility programs that allow you fix a wide variety of these problems.
Boot from local drive. After you boot from the Fedora media, if you decide you need to boot your system from its existing hard disk, choose this option.
