type (.) (dot) as your server name if you select (Defaul) in INSTANCE window during the sql server installation
dot means [local] for sqlserver.
if you choose a name like "bhv" for instance name you must type .\bhv for server name.
an you can select windows auth... if you are the user who install sqlserver in you machin.
you can select sql auth... and enter SA username and the password that you type in auth... window during sqlserver installation.
