I would suggest that you create a new database on the same server. You then need to retrive info on the datbase you setup using sp_helpdb NewDatabase. This together with info from the original database can be used in the following query to restore the database into the new location.

restore database DatabaseName from disk = 'G:\..\DatabaseBackup.BAK'

    with replace,

         move 'OrigDatabaseDataDeviceName' to 'G:\..\NewDatabaseDataDevice.MDF',

         move 'OrigDatabaseLogDeviceName' to 'F:\..\NewDatabaseLogDevice.LDF'
