how to move a .tib-backup image into the Acronis Secure Zone?

Hi,
I've made an image of my c: harddrive quite a time ago. Somehow, the image ended up on my c-drive. I now want to restore my c-drive using that image which is not possible as the image must not be on the harddrive being restored.

OK, this makes sense but leaves me with a problem: How can I move the backup image into the Acronis Secure Zone? (I am using ATI 10)
Maybe the problem is that the 10GB-partition created to store the backups is not properly identified by ATI. When I click on "edit Backup locations" I don't see any backup location. Although there is a 10GB "Type 77"-partition on my computer that was created for ATI as far as I remember.

How can I tell ATI to use that space?

Thanks in advance and best regards,
Claus
