Hard disk / page file

I bought a new 500 gig Seagate SATA drive to replace my aging 200 gig
drive. I used the DiscWizard to clone the drive (I thought). The
original drive had two partitions, one containing the HP recovery
stuff. I unplugged the old drive after the process, and the computer
would not boot. I plugged it back in to attempt a repair of some kind,
and it booted fine. In disk Management, it shows G: (the new drive) as
healthy system, and the C: drive (the old one) as pagefile. I decided
to just try the whole operation over again, and the Discwizard won't
let me reclone to the new drive, the option is greyed out. The
original plan was to replace the old drive and use it as storage.
Where did I go wrong? How can I fix this? Thanks ahead of time.
