I have got a lot of questions on how to install and run SQL Server on Windows Server 2012. Now we have released a knowledge base article that outlines the required software prerequisites for running SQL Server on Windows Server 2012. The article talks about all versions of SQL Server 2005, 2008, 2008 R2 and 2012. The article also contains known issues on installing, you can find the article here http://support.microsoft.com/kb/2681562
