Both grub and lilo store a minimal loader on the boot sector. This
minimal loader has sector map (list of sectors holding a file) for lilo
or grub stage 1.5. At this point the two differ. Lilo has a secor map
for each kernel/ramdisk. Grub stage 1.5 uses a filesystem to read
grub, which can read the config file, kernels and ramdisks off any
supported filesystem. Grub can also use a sector map for these files.
Now do you understand that the reason for all the holy wars in favour
of grub/lilo is that the most significant advantage to (insert your
favourate boot loader) is personal preferance?
If you want to boot a system with trashed filesystems, you cannot rely
on the copy grub or lilo on the hard disk. Make youself a boot disk/cd.
