7.2. 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, press the Tab key.
This option is the default. Choose this option to install Red Hat Enterprise Linux onto your computer system using the graphical installation program.
Install system with basic video driver
This option allows you to install Red Hat Enterprise Linux in graphical mode even if the installation program is unable to load the correct driver for your video card. If your screen appears distorted or goes blank when using the the Install or upgrade an existing system option, restart your computer and try this option instead.
Rescue installed system
Choose this option to repair a problem with your installed Red Hat Enterprise Linux system that prevents you from booting normally. Although Red Hat Enterprise Linux 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
This option boots the system from the first installed disk. If you booted this disc accidentally, use this option to boot from the hard disk immediately without starting the installer.
