The post describes how to install Oracle Enterprise Linux (OEL) and Red Hat Enterprise Linux (RHEL) in step-by-step procedure with screenshots. The procedure is based on Graphical mode. Even the text mode is also similar but there is no mouse, you have to use only Keyboard.

Oracle Enterprise Linux 4 (OEL 4),
