An Expert installation offers the choice of bootloaders: GRUB, LILO with a graphical menu, or LILO with a text-based menu.

You can also specify where to install the Linux bootloader in the "Boot device" section. The default setting will install it onto the master boot record (MBR).

If you already use a boot manager (such as System Commander, BootMagic, NT boot loader) you should choose to install the bootloader in the root partition of your Linux system (or even on floppy).
