Whee, recovering a crashed SQL Server

I unplugged my workstation accidentally. On reboot I got, right after the trace for ‘starting up master’:

17207 : udopen: Operating system error 3(The system cannot find the path specified.) during the creation/opening of physical device .

and

FCB::Open failed: Could not open device for virtual device number (VDN) 2.

and

Error: 5105, Severity: 16, State: 4.

Possible causes: database files being held open by virus scan, database files marked as readonly, or the master is hosed.

So I suppose master is hosed. I check for advice on restoring master. I tried the rebuild master utility, which kept failing with error -1. A BUG: report said I might need to restore from a copy of the install files from harddrive, not a copy from disk.

I publish more if I ever get the server back up without just doing a reinstall of the server.

Update: It was faster to reinstall SQL Server than to figure out how restore the master.
