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