Mac OS X Lion couldn’t be installed
When I finished upgrading my Mac book pro to the newest OSX Lion last week, I went on to do the same upgrade on my brothers Mac Book but on this occasion I encountered a difficult problem. This what displayed on the screen.
Mac OS X Lion couldn’t be installed, because the disk Macintosh HD is damaged and can’t be repaired.
This is a screenshot I took from Stack Exchange's Apple site's post because I did not remember how to take one on my brother's computer. Can you help on how to deal with this issue before my brother finds. Please show me in a step by step format because I am not that conversant with the PC. Thank you very much in advance.
