I am using macbookpro laptop and my updated version of Snow leopard 10.6.6 isnt booting up and the system gets shutdown aftr showing up the initial apple boot menu for a minute(apple symbol in a white background). I m using the boot camp windows nw and it show that "mac drive may have corrupted".But i mounted th drive in windows 7 and i got access to all my mac drive files which i have safely taken the backup. I tried to start using the mac driver cd and boot it frm the dvd drive by pressing on C but its not even goin to the next window aftr the boot menu,whr i cant even go to the Disk utility menu. This issue happened aftr finishing my work in windows and restarted from windows 7 to Mac,but whn th windows 7 got switched off, a blue window with error msgs poped up.I switched off th blue window by pressing on power button.I switched on the power button but mac isnt booting aftr tht issue. I thnk the OS got corrupted and hard disk is still safe (becs i could access th mac files thru bootcamp widows7) Pls help me in this issue ???
