help with os load

[indianchief]

I have a think pad 770. I made the mistake of thinking that it worked like a desk top unit. Anyway, I set the hd partition to support large and formatted the disk. The problem I have now is , when I try to load the windows 98 cd the screen says invalid system disk. I took the cd to my desk top and explored it , it does not seem to be an autostat cd. What can I add to the cd to make the thinkpad see it as an system disk so it will start. Any help would be greatly appreciated. I may have more than one problem
