Creating new database from a backup of another Database on the same server?

I am trying to create a new database from an old backup of database on the same server. When using SQL server management studio and trying to restore to the new DB from the backup I get this error

System.Data.SqlClient.SqlError: The backup set holds a backup of a database 
other than the existing 'test' database. (Microsoft.SqlServer.Smo)

after googling around I found this piece of code

    RESTORE DATABASE myDB

 FROM DISK = 'C:\myDB.bak'

 WITH MOVE 'myDB_Data' TO 'C:\DATA\myDB.mdf',

MOVE 'myDB_Log' TO 'C:\DATA\myDB_log.mdf'
GO

I was wondering will the move statements mess with the database that the backup came from on that server?

Thanks, all help appreciated.

What I should to do:

• Click on 'Restore Database ...' float menu that appears right clicking the "Databases" node on SQL Server Management Studio.
• Fill wizard with the database to restore and the new name.
• Important If database still exists change the "Restore As" file names in the "Files" tab to avoid "files already in use, cannot overwrite" error message.

What I do

IDk why I prefer to do this:

• I create a blank target database with my favorite params.
• Then, in "SQL Server Management Studio" restore wizard, I look for the option to overwrite target database. It is in the 'Options' tab and is called 'Overwrite the existing database (WITH REPLACE)'. Check it.
• Remember to select target files in 'Files' page.

You can change 'tabs' at left side of the wizard (General, Files, Options)

It's even possible to restore without creating a blank database at all.

In Sql Server Management Studio, right click on Databases and select Restore Database...

In the Restore Database dialog, select the Source Database or Device as normal. Once the source database is selected, SSMS will populate the destination database name based on the original name of the database.

It's then possible to change the name of the database and enter a new destination database name.

With this approach, you don't even need to go to the Options tab and click the "Overwrite the existing database" option.

Also, the database files will be named consistently with your new database name and you still have the option to change file names if you want.

Checking the Options Over Write Database worked for me :)

Think of it like an archive. MyDB.Bak contains MyDB.mdf and MyDB.ldf.

Restore with Move to say HerDB basically grabs MyDB.mdf (and ldf) from the back up, and copies them as HerDB.mdf and ldf.

So if you already had a MyDb on the server instance you are restoring to it wouldn't be touched.

The script in the question is just missing the replace statement so the restore script will be

RESTORE DATABASE myDB

 FROM DISK = 'C:\myDB.bak' ,

 WITH MOVE 'myDB_Data' TO 'C:\DATA\myDB.mdf',
,
MOVE 'myDB_Log' TO 'C:\DATA\myDB_log.mdf' ,  NOUNLOAD,  REPLACE,  STATS = 5
