I formatted the PC and I'm trying to install SQLServer Express 2014 with a tutorial on youtube, but when it arrives at that point of my installation, it does not come all the same as the video.
Note: I have already installed once and simply sql did not give me the option to change my instance, and I could not log in by putting the default instance " PC name \ SQLEXPRESS ".
This is the second time that you format your PC because of SQL. Help me!
I downloaded SQL directly from Microsoft's website and I'm using Windows 10
