The second &architecture; boot loader is called LILO. It is an old complex program which offers lots of functionality, including DOS, Windows, and OS/2 boot management. Please carefully read the instructions in the directory /usr/share/doc/lilo/ if you have special needs; also see the LILO mini-HOWTO. Currently the LILO installation will only create menu entries for other operating systems if these can be chainloaded. This means you may have to manually add a menu entry for operating systems like GNU/Linux and GNU/Hurd after the installation. &d-i; offers you three choices on where to install the LILO boot loader: Master Boot Record (MBR) This way the LILO will take complete control of the boot process. new Debian partition Choose this if you want to use another boot manager. LILO will install itself at the beginning of the new Debian partition and it will serve as a secondary boot loader. Other choice Useful for advanced users who want to install LILO somewhere else. In this case you will be asked for desired location. You can use traditional device names such as /dev/hda or /dev/sda. If you can no longer boot into Windows 9x (or DOS) after this step, you'll need to use a Windows 9x (MS-DOS) boot disk and use the fdisk /mbr command to reinstall the MS-DOS master boot record — however, this means that you'll need to use some other way to get back into Debian!
