title: How to create instance in SQL Server 2008
body: <p>I have SQL Server 2005 Express installed. Later I upgraded to SQL Server 2008. I don't know much about instances, but when I log into SQL Server 2005 and I log into SQL Server 2008 it is showing the same number of databases. Also, when I create a database in SQL Server 2008 it is showing it in SQL Server 2005.</p>
  
  <p>Any Idea how can I create a separate SQL Server 2008 instance?</p>
  
  <p>If possible please explain step by step.</p>
  
  <p>Thanks</p>
