restore the backup to a NEW (not yet created database)...Where you previously set the database to "restore to" there should be an option to create a new one (you may have to type in a new name before it prompts about creating a new one).  You'll need to check the overwrite data box.  <-- That may've been the issue with your first try.

Can you try to instead copy mdf and ldf files for copying the database schemas?
RayData AnalystCommented:
When you copy MDF and LDF, you get data too.  Also, attaching them is tricky (but can be done).
