Thanks for the quick responses. It is on the C drive currently, as it's the first visible dos drive. I don't know much about chain loading. What steps should I take? The grub4dos post I saw, but I still can't figure out how to do that. I am attempting to install grub without installing Linux at the moment. Certainly not easy. If LILO can do it that'd be great, because lilo is on the system. I just need to know how to set it up in lilo.conf.
