I've just ruined my mac os x by trying to over-installed windows 7 without using bootcamp, and Windows wouldn't install as it needs NTFS format of HD, now i'm totally stuck!!! no mac os x, no windows 7!!! when I start my macbook, there's a "?" come up. Any suggestion for my stupid act would be much appreciated!!!
*Note: I don't have an os x dvd!
boom
