I guess that I have to ask...if you wanted to attempt a System Restore operations...why did you not do that when the system booted into normal mode?
What made you decide to attempt the SafeModeRepairKey program, rathe than SR?
STOP 7E errors, see left column at http://www.aumha.org/a/stop.htm
Based on the info provided thus far, it would sheer speculation to guess at what is going on
System manufacturer and model?
