Thank you, thank you all.
I am back in business. Without going back through the thread to single people out, let me say that the advice here gave me the clues I needed. It also pointed out how reliable Ghost is, if sometimes a bit confusing.
Here's how it ended up. The biggest mistake I made in the beginning was going ahead with the Restore when "Restore MBR" was grayed out. I should have stopped right there, taken a deep breath, and started over. Instead, I plowed on. This, plus somehow doubling up on choosing partitions to restore, left me with a hard drive that had two identical copies of my original C partition and one of my original D. It was not bootable. Then I spent hours trying to add an MBR, using a Windows 7 installation disk in Recovery Console mode, and then in Command mode. Nothing got my new drive into a bootable mode.
This afternoon UPS showed up with a SATA to USB connector kit. I was then able to hook up my new laptop drive to a working Windows 7 machine. I could then do what someone above recommended. I just deallocated the whole drive. I couldn't do this before because I had no way to access the drive. However, I had assumed that since it was brand new, it would have been unallocated, but I couldn't be sure.
Then I booted up the Ghost 15 cdrom. I chose Restore and it found my Ghost recovery points for C and D but only let me choose one, as it had the first time. Obviously, I chose C. Again, it showed with Restore MBR grayed out. But this time I did not execute the restore and then restart Ghost to get D restored. That was my mistake before, that resulted in two C partitions being created, and no MBR.
Somehow, I'm not sure, I got to a screen with both C & D checked in a box. I saw that C gave me the Edit option. It was there that I could check Copy MBR.
My first post may have led some of you astray when I said it was Ghost 12. The latter doesn't have the Edit mode that 15 does. Maybe it defaults to Restore MBR, where Ghost 15 defaults to graying it out.
Anyway, at this point I just let Ghost do its thing. After an hour and a quarter, I was able to boot up normally.
Again, thanks to you all.
