I've MacBook Pro HD (late 2011) with Maverick and a Bootcamp partition.
Yesterday, when I turned on my Macbook it made thestarting sound, showed the Apple logo and a progress bar. The progress bar completes and then Mac turns off.
But BootCamp is working fine. I have installed MacDrive on my win-7 in bootcamp. When win-7 starts it shows me following popup: macbook pro hd was not safely disconnected when last used, and may contain errors
.
OS X partition's data is totally accessible from Windows.
One thing that is to be mentioned that last day before problem, there was an update to Maverick was available to App Store, I started to download it. Don't know downloading was completed or not. (Just to inform)
I've tried some solutions but didn't worked for me. Any suggestions?
