Please be sure to create a boot disk. In a case such as this, you will either need to use the boot disk, or configure the NT system loader to boot LILO from the first sector of the root partition. The Use linear mode button is selected by default. If you wish to add default options to the LILO boot command, enter them into the kernel parameters field. Any options you enter will be passed to the Linux kernel every time it boots.
Every bootable partition is listed, including partitions used by other operating systems.
Other partitions may also have boot labels. Once selected, you can change the boot label. If you do not want to create a boot disk, you should deselect this option. However, we strongly urge you to create a boot disk. This is handy if you're trying Red Hat Linux for the first time, and you'd feel more comfortable if the boot process for your other operating system is left unchanged.
