Greetings reader, I have installed windows 7 ultimate english on a laptop and now it kinda went down...does not go through the windows loading screen..I tried repairing with the same retail Windows 7 ultimate english but it kept saying "This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of windows." I did install another language from windows update which is now currently down...and also upgraded to Windows7 SP1..that is why I cannot use the same Windows 7 ultimate I bought earlier? another way I could get the windows running without re-installing it? safe mode does not work either nor does the launch repair thing... help...please.
