Ah, okay, that makes sense. Here's the next thing I would try: reboot the computer, holding down the Option key until it shows you one or more disk icons. Choose the one for your old drive, and see if you can boot into the old system. If so, do what I suggested previously, and you should be in good shape. If it won't boot from the old drive, report back and we'll figure out the next thing to try.
