Selecting the Installation Type for Fedora

If the installer finds Fedora on your hard disk, it asks whether you want to upgrade or install a new version. The instructions in this chapter are for a new installation.

A Linux computer can serve many purposes. The next screen displayed allows you to select a type of installation for your computer. The choices are shown in Figure 4-7.

Figure 4-7. Installation type screen in Fedora Core 2.

Select one of the following choices:

Personal Desktop provides a desktop and a selection of desktop applications. It includes office applications. This choice removes all existing Linux software on your hard disk, but leaves any Windows software in place.
Workstation includes the applications provided by Desktop and adds tools for software developers and system administrators.
Server is not designed for desktop use. This choice will remove all other software, including Windows, from your hard disk.
Custom allows you greater flexibility, but you must know what you are doing.

In the remainder of the Fedora instructions, the choices are based on a Workstation installation. If you choose another type, you may see small differences in the screens displayed.
