Macintosh HD is damaged and cannot be repaired.
I recently downloaded and tried installing the new Mountain Lion OS X. After the download i followed all the steps and when i had restarted and started installing, it came with the warning: Macintosh HD is damaged and cannot be repaired, and that i should restart my coumputer. I have tried this several times, and nothing has helped. I have bootcamp on my computer and my windows side works perfectly fine. When i tried looking through my Mac sides files i found a file called OS X install data. I was wondering what would happen if i deleted this file. and how i can fix my problem?
thanks.
