Cannot find my default instance

Hi,

I'm using SQL server 200 Personal Edition. I had a named instance created at the time of installation and a default instance later. Now my default instance crashed and I want to rebuild my master db. But neither can I find my default instance in the drop down in the rebuildm dialog box (Only the named instance is present) nor is it allowing me to edit the server name in the drop down. What should I do?

Thanks in advance.

Each instance has its own set of services. Look for the name following the $ in the service name, or the value in () depending on your installation and OS.
