Boot Loader Configuration: The installation program provides two boot loaders for you to choose from, GRUB and LILO. 1.GRUB (GRand Unified Bootloader) 2. LILO (LInux LOader) LILO (LInux LOader): LILO stores information about the location of the kernel or other operating system on the Master Boot Record (MBR).
- 9. GNU GRUB (GRand Unified Boot loader) GRUB has a more powerful, interactive command line interface GRUB will default to its command line interface where the user can boot the system manually. GRUB may have difficulties booting certain hardware. LILO and GRUB do have a number of differences: * LILO has no interactive command interface, whereas GRUB does. * LILO does not support booting from a network, whereas GRUB does. * LILO stores information regarding the location of the operating systems it can to load physically on the MBR. If you change your LILO config file, you have to rewrite the LILO stage one boot loader to the MBR. Compared with GRUB, this is a much more risky option since a misconfigured MBR could leave the system unbootable. With GRUB, if the configuration file is configured incorrectly, it will simply default to the GRUB command-line interface. Boot Loader Configuration
