Sql-server – Create a new database in SQL Server 2008 R2, but it is not Blank

There is a hack you can try: where you create a dummy DB with the same name and size as your old data and log files. Then you have to stop SQL server, replace the new empty files with the old files that have data in them.

Check out this blog link by Paul Randal where the hack is explained in detail. It looks like you have tried the first method mentioned, but read along and try the other methods. Please let us know how it goes. I do not know how well it will work without log files, but it is worth a try.

Instead of using maintenance plans, check out Ola Hallengren's free maintenance stored procedures. They're way more powerful than maintenance plans and they don't require SSMS (per your requirements) to implement. You can set them up with any T-SQL connection.
