It means that there is no Windows there or you booting from the wrong drive .

well, windows is installed because I was chatting and then it froze so I had to re-start it...
and How do I know which the correct drive is,
I don't know what to do...
besides, It sometimes says that I have to insert the cd to solve the problem and when the scan is over Its says It was impossible to repair so I don't know what to do...

If you was using it before that's mean you are booting correctly and your cables are fine and your ram in place ..can you boot in safe mode ?.. another thing when you try to repair choose system restore and see how you get on ..
