Microsoft SharePoint Server 2010 encountered an error during setup / Exception: System.Data.SqlClient.SqlException: Could not find stored procedure 'sp_dboption'

Try installing sp1(service pack 1) for Sharepoint 2010 and then try to install SharePoint 2010

or Run SharePoint Configuration Wizard

It may sound weird to install Service pack before you install SharePoint but it worked for me twice J
