Yes. This all assumes that you don’t want to start from the scratch. Of course, if you’re willing to lose the DB data, the easiest way would be just to drop the DB (using the Delete DB button in the Maintentance tool), delete the physical files (.ldf including) and recreate the DB (again the Maintentance tool).

But I believe the backup → delete → delete_files → restore path should work as well…
