Moving files from back up to new internal drive

You can't drag and drop, no. You can migrate or restore (the "Recovering from a disaster" section of the User's Guide goes into lots of detail)... and, yes, you can also Migrate, assuming the backup is properly written directly to the drive.

Here's what I did.

I got the new Seagate drive. I formatted it Mac OS extended. I did not create any partitions on it.

I then used SuperDuper to copy "from" my internal drive "to" the (backup) external Seagate. Along the way, I verified and repaired both drives using both DiskUtility and DiskWarrior. Apart a few permission repairs, no problems appeared. (Would any of this constitute verifying the partition scheme? If not, how do I do it?)

Moving right along. As a dry run, I then simply reversed the copying procedure. Again using SuperDuper I copied "from" the (backup) Seagate "to" the internal drive.

I then restarted, and using the option key, selected the internal drive as my startup drive. It was recognized and started up fine. So it seems I don't have to use the Restore or Migrate features to transfer my stuff when my new drive gets installed later today.

The external Seagate is still not recognized as as startup drive. Is there a way to do that without erasing the drive and starting from scratch? And if not, any suggestions on how to create a bootable Seagate drive once my files get moved to my new internal drive? The tech people at Seagate tell me that it should be bootable on a Mac, no firmware or other issues are involved. Can't quite figure out what I neglected to do.
