install windows 98 in thinkpad

I bought a thinkpad, it was suppose to have 98 on it, and come to find out they reformatted this drive. I put my 98 disk in to install, and it is stuck on c:/> I have entered everything in the world i can remember from programming to try to get it out of that, and where i can get it to recognize the cd being there, so i can install 98, and nothing is working. Please help, im getting frustrated. Thanks, Brenda
