You can't overwrite instance names, you will have to uninstall the old one and re-install with the new instance name.

Question
I'm trying to install SQL Server 2012 on Windows 7 64bit. In the first time, my laptop crashed during "Installation Progress", so I have to cancel the installation from Windows Task Manager by ending process.
Now I want to do installation again and replace everything that has already been there. However, since I set the instance name as MSSQLSERVER2012 during the first time, it requires me to set a new one. How could I just overwrite the existed one? Or I have to set a new one and delete the old one after installation? Thx!
