You do not require multipule OS to have Lilo, I am sorry but, I  do not know how 
are you relating Multipule OS, LILO and Linix Single

Linux single is a run level

Lilo ia the linux loader, that can load Linux or other OS or diff versions of 
kernels. Infact I have my system that is three diff kernel booting, with what I 
type at lilo, and I do not have any other OS on that.

Thanks
