SQL Server 2012 Support on Windows Server 2008 R2 Is it possible to install Microsoft SQL Server 2012 on Windows Server 2008 R2 Datacenter?

On the Windows Server 2008 R2 Datacenter - I have .Net Framework 3.5.1 Features(.Net Framework 3.5.1) and I even manually installed .Net Framework 4.


  The operating system on this computer does not meet the minimum requirements for SQL Server 2012. For Windows Vista or Windows Server 2008 operating systems, Service pack 2 or later is required. For windows 7 or windows server 2008 R2, Service pack 1 or later is required.

I tried to install Microsoft SQL Server 2012 Service Pack 1 &amp; 2?
Yes, you can install SQL Server 2012 on Windows Server 2008 R2 (the matrix here - which is exactly where the link in your screenshot goes, if you had clicked it - shows the supported edition/OS combinations). 

The error message you posted tells you exactly what you need to do without even going to that page: Apply Service Pack 1 to the operating system. 

(Though - especially if setting up a new system - you should consider a more modern operating system, and a newer SQL Server version for that matter.)
