Can’t Install XP

I formatted my drive. Then, using a w98 boot disk to start the comupter, I try installing XP with the CD via e:\i386\winnt. It does the “dos” portion completely and then says it needs to reboot. When it reboots it says “No Operating System”. I’mnot sure what file it wants to see when it boots, but XP does copy many many files to my drive. I tried Windows 2000 also with exactly the same results. Can anyone help please?
