    I'm using a MacBook Pro retina, I used boot camp to play PC games and install softwares.
    But recently I used EaseUS partition manager trying to increase the partition space, but I think I accidentally deleted the Macintosh HD partition. And now I can't open Mac partition on my MBPr . Everytime I restart the computer, it would show a grey screen,

    Then it would just show this screen, asking me to choose an OS to start,
    Choose OS
    And it would just open the Windows Boot Camp partition.
    But when I click into my computer, you can clearly see the Mac partition there with all the things inside (you can even take things from it)

    And here's a shot of how the partition manager looked(ignore Disk 2, that's my phone)

    I want to know why is this happening and is there anyway to fix it? Or do I need to bring it back to Apple Store?Plz help!!I beg for your help!!

    It seems to be a volume corruption case as your Macintosh HD is visible but you are not able to start your Mac. You need to pull out your drive and attach it with some working Mac and repair your Volume. When the volume get repaired and mounted you can easily start your Mac with Macintosh HD. Good Luck and use a Volume Repair Tool which can be helpful.
