Part I ✦ SUSE Linux Basics
Linux systems typically use one of two boot loaders, LILO (Linux Loader) or GRUB
(Grand Unified Boot Loader). Both are very powerful and flexible, and are controlled
by easily edited configuration files (
/etc/lilo.conf and /etc/grub.conf, respec-
tively). The key difference between the two boot loaders is how they interact with
these configuration files. If you use LILO and update its configuration file, you must
rerun the
lilo command to update the system boot information that is stored on
your disk. GRUB automatically rereads its configuration file whenever you boot
your system and therefore does not require that you update any other system boot
information.
A few years ago, the general consensus was to move away from the LILO boot
loader to the GRUB boot loader. GRUB provides a more robust boot loader, and the
default configuration is fine for most users. If YaST detects a Windows installation,
it adds this as a boot option, providing a means to dual-boot Windows and Linux
on the same system.
YaST will already have configured your boot loader, depending on your system con-
figuration. This also includes any Windows installations that have been found. To
edit a boot loader entry, select the relevant entry and click Edit. You will be pre-
sented with the boot item configuration screen shown in Figure 1-18.
