Q: Unable to load OS X after installing BootCamp
-
Sep 7, 2016 12:40 PMby Loner T,Mini Partition Tool is one of the worst tools to manipulate anything on a Mac.
Do not modify any partitioning information. Can you Alt/Option key (not Control) and see Appel Bootmanager?
If not, can you use Command+R to boot into Local Recovery or Command+Opt+R to access Internet Recovery when booting up?
What is the year/model of your Mac?

Sep 7, 2016 12:46 PMby Kiraweiloon,I have unfortunately already edited the 'unallocated' space (appoximately a few hundred mb) and now i have no way to boot into my OS X. I think that is the reason why i am unable to boot into OS X.
The unallocated space just shows empty and i have allocate it to my ‘Windows' and now i can't boot it.
Before this problem exist, i will just press option when i hear the boot up sound and choose OS X. But this option is gone, all i can see it Windows.
I am not willing to delete my OS X because i have plenty of important files in there.
Is there any easy way to solve it?I am using the Late 2013 15" Macbook Pro with Retina Dispaly

Sep 7, 2016 1:38 PMby Loner T,Can you use Command+R to boot into Local Rovery or Command+Opt+R to access Internet Recovery when you power up the Mac?

Sep 7, 2016 10:02 PMby Kiraweiloon,Yes, i can access Internet Recovery. I am unable to boot into Local Recovery though.
Holding Command+R/Command+Option+R only allows me to enter Internet Recovery. I can't seem to do anything there. I tried to Re-install Mac OS X but it states that 'The disk cannot be used to startup your computer'.
What else can i do? -
Sep 8, 2016 2:11 AMby Loner T,In Internet Recovery, click on Utilities -> Terminal, and run the following commands...
diskutil list
diskutil cs list
gpt -vv -r show /dev/disk0
fdisk /dev/disk0
Use Copy (Command+C) to copy the entire output of all four commands, quit Terminal, start Safari, and Paste (Command+V) the output as a reply in this discussion.

Sep 8, 2016 3:32 AMby Loner T,You have a missing Recovery HD (about ~650MB / 620MiB ). I assume you have tried to 'edit' this space.
Do you have a Time Machine backup of OS X?
Do you have a backup of Windows?
Are you willing to re-install Windows?
If you do not have an OS X backup, Internet Recovery offers to re-install the 'shipped' version of OS X, not the 'current' version of OS X, as documented in About OS X Recovery - Apple Support.
I suggest not installing the shipping version of OS X on your current internal partition.
Please use How to install OS X on an external drive connected to your Mac - Apple Support and install the version offered using Internet Recovery to an external disk or a flash drive or SD card, upgrade it to the version that you currently have on your internal disk, boot from this external disk and use it's Local Recovery to re-install OS X on the internal disk.
Re-installation of OS X does not touch any non-OSX files.

Sep 8, 2016 9:09 AMby Kiraweiloon,Sadly, i did not have any backup for OS X because i have re-allocate the size before and everything works fine for a few times and i didn't backup at all due to that but this time round i have no idea what is wrong.
My bootcamp (windows 10) is a free trial which i downloaded from online. I am willing to re-install my Windows since most of the things i have here are games, i am just not willing to lose my OS X stuffs because it contains my school work.
How much space do i need to install the version (10.11.6) i currently have?
Will i lose my OS X items? -
