Hello. What was the original trouble or reason for trying to start in single users mode?

Also based on this message in your log:

2011-05-25 18:17:24.53 server initconfig: Error 3(The system cannot find the path specified.) opening 'I:\data\master.mdf' for configuration information.

Have you confirmed that that location and file exists and is accessible? ('I:\data\master.mdf')
