Red Hat Linux defines three installation types: Workstation, Server, and Custom.
If you’re new to Linux, the workstation installation type is probably the most appropriate for you, especially if you currently run Microsoft Windows. In that case, the workstation installation procedure will automatically configure your system to dual boot—whenever you start your system, a Linux utility known as LILO will give you the choice of starting Microsoft Windows or Linux. Both operating systems can reside on a single system. A workstation installation requires about 600 MB of free disk space.
The server installation type automatically removes all existing data from your hard disk. You should use it when you want your system to run only Linux. A server installation requires about 1.6 GB of free disk space.
The server installation type destroys all data on your hard drive. Do not perform a server installation if you want to preserve any data on your system.
The custom installation type gives you complete control over the installation process. You specify whether to configure your system for dual boot, what software packages to install, and so on. The custom install is covered in detail in the next chapter, but a workstation or server install can offer a quick way to get started unless you need to preserve data on the target machine.
