I have a bad sql server install. I mistakenly installed 1st time with default instance which i dont wont and then uninstalled it and later on try to install with named instance but it would error out in the middle of installation and i just close out and manually start sql server and it would start but not the agent. I even cannot connect to the database engine with the Virtual server name i mentioned. After researching thoroughly i realized both sql server and agent were missing the "VirtualServername" entry in the sql server properties -> Advanced -> Virtual Server Name from the configuration Manager. Now the question is can i manually enter my server name in there?
