Q: MacBook Pro wont boot into OS X after dual booting with windows 8.1 via Boot Camp.
hello i came here after trying to find a way out to boot into mac os x. Google was very confusing..i am hoping to get my problem sorted out here..hope you guys can help me out.
I installed windows 8.1 via Boot Camp and it installed successfully on my MBP. Windows works like charm with all the necessary drivers installed via Boot Camp. The problem is when i tried to reboot and get into my Mac OS El Capitan it crashes. I held down the "options" button when i restarted the laptop and it showed me both operating system to choose from. "Macintosh HD" and "Windows". When i clicked on Macintosh hd it showed the apple logo and loading progress and then suddenly it crashed with lots of error writings on the start up apple logo page.
When i click in Windows it boots into windows 8 but i am unable to use my Mac OS. Is there anything i can do to get my Mac OS working again.
MacBook Pro, Windows 8

ok ..so i got in touch with Apple chat support and finally we worked out a solution...and now both my OS works.. Mac OS X finally works with all the files and info untouched ! and my Windows 8.1 Pro also works excellent via dual boot.
ok so if any of you have faced the same problem as mine i will tell you what i did to overcome this scenario. i restarted my mbp and went into recovery mode by holding "cmd+R" button at restart till i heard apple logo and start up sound ... then i went into recovery mode ..and selected "disk utility".
as you can see there are two partitions. One for Mac OS X el capitan in "Macintosh HD partition" and Windows 8.1 pro in "Bootcamp partition". You can clearly see that Macintosh HD is showing full volume used and no available data can be modified or tampered with. I learned it while having a chat with Apple chat support that i have used "filevault" to encrypt my hardisk !.... view image below.
it shows "zero KB" available since its filevault protected...so i had to first unlock it. To do that i clicked the "file" option of Disk Utility and clicked "unlock" and i entered my admin password and unlocked Macintosh HD.
i first clicked on the whole HDD and ran first aid check on it...it showed the above result...
After this i clicked the "first aid" button above in Disk Utility on Macintosh HD and it automatically checked in for disk errors and did its check up and it came out successfully for me. and i restarted my mac and it booted straight into Mac OS X el Capitan. (sorry i did not take image of it as i got too carried away with happiness).
