Need help right away! LI problem with lilo. no boot disk!

[Duh]

lilo starts up, ends at LI. i know i probably just need to rerun /sbin/lilo and rest it, but i have no boot disk! i booted to the RH 7.1 cd, went under rescue and tried. but it dells me it doesnt know what to do with device 0x0100 or similar number.
can i make a boot disk somehow?

BTW: that PC has linux only, using another win pc i can use if needed too.

Did you look on your install CD?

I don't know of one that doesn't include a bootdisk image.
