As a DBA, I have been in many situations where I had to move databases to a new server due to old hardware, failed hardware, failed drives, etc. You have two options you could use to carry out this task:
SQL Server Management Studio (GUI)
T-SQL (Command line)
The method I prefer is T-SQL. It is simple and easy and avoids clicking the mouse all over the screen. This How do I... will show you both methods and allow you to choose the one you prefer.
