and I continued setup but I could not found SQL Server Management Studio tools in start menu
As mentioned, you have missed installing SSMS. You can go through the install process again (you don’t need to uninstall, just run it again), except this time make sure you put a check mark next to the Management tools when you do feature selections. I’d tell you exactly where it is but i only have a SQL2008 install on hand at the moment.
