(Solved) SQL Server 2008 R2 Uninstallation:No feature were installed during the setup execution

I had to clean uninstall SQL Server 2008 R2 before I could plan fresh installation of SQL Server 2012. 
I tried uninstalling SQL Server 2008 R2 from Control Panel --> Add/Remove Programs. However, I was getting the below error.

 

Also tried removing the individual SQL Components through the below command, as per the article http://sqlblog.com/blogs/aaron_bertrand/archive/2010/10/25/fun-with-software-uninstalling-sql-server-2008-r2-evaluation-edition.aspx

rem DisplayName
msiexec /x "GUID"
However, it did not help.

Solution worked for me was:
1. Re-run the SQL Installation Media, add few more features to the SQL Installation on the machine.
2. Now, from the Add/Remove Programs, uninstall SQL Server 2008 R2 Setup --> Select the installed instances/default instance and remove.
3. If you see any shared features installed that also need to be removed (possibly before step 2 above), for proper SQL Server Uninstallation.
4. Refresh the Add/Programs, now the SQL Server Setup should not be listed in there.

Thank You!
