I did this twice, instaled win 7 using booth camp. The problem started when I boot os X. Every launch new aplication I saw 30 minutes of that creapy rainbow, just all os X freeze for this time, I could just wait. restarting os X doesn't helped.. so I must restored partition of Win7. My only hope is probably full reinstal os X right? /i just reinstal os X 1 mounth ago.. :-X
