I have a Dell studio xps with two 750 gig HD's. My question is which one has the OS on it?

Solution
what do you mean by "that disk"? just locate in windows's disk manager the C drive, look at it's serial number, copy it onto a price of paper (or at least the begining), and try to see on the physical hard drives which one has that serial number.
