Installation Location Boot Labels The Default Boot label column will be filled in with the word linux on the partition holding your Red Hat Linux system's root filesystem. Other partitions may also have boot labels. If you would like to add boot labels for other partitions (or change an existing boot label), highlight the partition, select OK, and press Enter. The Default Boot label column lists what you must enter at LILO's boot: prompt in order to boot the desired operating system. However, if you forget the boot labels defined on your system, you can always press Tab at LILO's boot: prompt to display a list of defined boot labels.
