I just replaced my primary hard drive. I partitioned the 100 gigs in half. Upon completing installation of the OS, I find that the computer has designated the first partition as the "C" drive but the second partition is "E" with the separate hard drive as "D". Is there an easy, painless way of making the second partition the "D" drive and the separate hard drive the "E" drive? Thanks, in advance, for the help and advice.
