HELP!! I can't access my macintosh HD when Booted!

Hi, I am new at this forum, so bear with me guys 😀

Anyway, i am experiencing some problems with my Macbook 15" i7 2012 model.. I just bougt it on april 5th 2012..

I have installed windows 7 on bootcamp, and currently running max os Lion

currently i am having issues accessing the mac os itself.

When i turned it on and off or restart it, it always gives me a bootup screedn that said Mac OS Utilities, just like the picture in this link : http://www.apple.com/osx/recovery/

I tried restarting it several times, it does not boot up my Macbook, to my desktop. I trist the windows it works just fine.

Then i tried recovering it 3x, which each takes 6-7 hours to do it. and it still always keep booting up the same thing over and over again.

i tried re-installing the OS, but its always giving me message, "this mac os lion is damaged, cannot be installed in this computer" something like that.

IT'S really frustraating, i've been trying to fix it a day or so, it still wont boot up my Desktop..

I tried restaring it and choosing my disk "Macintosh HD" but it still gives me a recover screen. I also tried pressing the option key then choose my disk, and it still doing the same thing.

PLEASE i need helppp!! someone anyone, what should i do!

MacBook Pro, Mac OS X (10.7.4)
