Setup Mode (64-bit)
This topic applies only to SQL Server 2000 (64-bit).
Use the Setup Mode page of the Microsoft® SQL Server™ 2000 (64-bit) Installation Wizard to choose whether to create a new installation or work with an existing instance of SQL Server.
Start a new installation
Creates a new installation of SQL Server 2000. Choose this option to create either a default or a named instance of SQL Server, or a SQL Server failover cluster. You can use this option to install any or all of the following features: the SQL Server relational database engine, Analysis Services, or Books Online. If a cluster is detected, Virtual server is selected by default. If no cluster is detected, Local Instance is the only selection for this release of SQL Server 2000 (64-bit).

If you currently have an instance of the beta release of SQL Server 2000 (64-bit) installed on your computer, your options for working with an existing database will be to utilize the backup/restore or detach/attach processes to preserve your current databases
