Q: OS X not starting up with stopped progress bar

Hello.

In my Macbook Pro Retina 13inch Late 2013, OS X cannot start up since 11 Oct 2015, and just shows the apple logo and a 1/5 progress bar.

I tried all of the methods which Apple suggested on their support page, but there's no progress.

Bootcamp works totally okay, so now I am using Windows 8.1 Enterprise 64bit on my Macbook.

And for some reason, I see two of "Mac HD"s in the OS selecting screen after those methods, also I see a Mac HD below Windows' "This PC" directory.

I wanted to write down my OS version, but because I cannot start up my OS X, I cannot see exactly which ver I was using.

I remember it was Yosemite and I didn't mean to upgrade to EC, though it might have upgraded automatically if there's such a function.

MacBook Pro with Retina display, OS X Yosemite (10.10.5), Windows 8.1 Enterprise 64bit

Hello Eric, thank you for your quick reply.

Unfortunately, however, I have already tried safe boot, PRAM reset, recovery mode, single user mode, and so on which are written in such webpages for startup problems.
They did not solve my startup problem.
So I assume the OS X itself has likely broken, but machine is fine because I can bootcamp without any problems.

Also, I am wondering if the data on both mac and windows can be safe or not when I re-install OS X in the Apple store?

I think it might be too complicated to suggest a solution for this problem, but I will appreciate if anyone has any ideas on it.

The data should be safe, but oops do happ[en

Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Then re-install the OS.
