Business Intelligence Development Studio installation for Visual studio 2010 problem

I want to install Business Intelligence Development Studio for doing report development in Visual Studio 2010, however in my installation process, I cannot find BIDS in the feature selection. What I have done is: - Install Visual Studio 2010 - Upgrade Visual Studio 2010 to SP1 - Installed SQL Server Data tools - Lastly, tried to install SQL server 2008 for BIDS feature. But it is not in the feature selection list What is the matter for this problem? Is there anything that I need to install before I install SQL server 2008? If there is, can I have the link?
