How to Delete Restoring Database
RESTORE DATABASE dbname 
FROM DISK = 'dbname .bak'
WITH REPLACE, RECOVERY --force restore 


or just

RESTORE DATABASE dbname WITH RECOVERY


the REPLACE Overwrite the existing database, do it only if you are sure you want to override your existing database as you mentioned you dont care to delete it

RESTORE WITH RECOVERY is the default behavior which leaves the database ready for use by rolling back the uncommitted transactions. Additional transaction logs cannot be restored.

That should bring the database online. Then you can delete it &amp; try again.
