Q: Can't boot after formatted NTFS partition

Somehow you have managed to format your OS X volume with NTFS making it unusable. I recommend you do the following:

Clean Install of El Capitan

Restart the computer. Immediately after the chime hold down the Command-Option-R keys until a globe appears.

The Utility Menu will appear in from 5-20 minutes. Be patient.

Select Disk Utility and click on the Continue button.

When Disk Utility loads select the drive (usually, the out-dented entry) from the side list.

Click on the Partition tab in Disk Utility's main window. A panel will drop down.

Set the partition scheme to GUID.

Set the Format type to Mac OS Extended (Journaled.)

Click on the Apply button, then click on the Done button when it activates.

Quit Disk Utility and return to the Utility Menu.

Select Reinstall OS X and click on the Continue button.

This should install the version of OS X that was pre-installed when the computer was new.

Well, you stated the following: OS X boot option suddenly missing after I have formatted NTFS(bootcamp) partition to installing Windows.

So unless your drive has failed, I'm afraid that is what happened. You most likely selected the wrong partition when trying to format your Windows volume. It is a common mistake.

If you can perform a Network Restore from your model, then that's what you will need to do.

Trust me when I tell you that you are incorrect. The Windows formatter will format anything if you select the incorrect partition. So, it is a mistake. But if you would prefer not to believe me, then please offer another explanation.

Why you think it's incorrect partition when it(HFS+) can't visible in Windows. No one can select INVISIBLE partition to read or write and impossible to format it by mistake.

 

Windows mounted only NTFS and FAT partition. That's why I'm SURELY It's not wrong partition. I'm select NTFS partition from 'My Computer' recheck name, recheck file system and size of partition before format it carefully.

 

So, please answer my question

"Is it have any solution to boot it up again or access my files in mac partition to do backup?"

 

The Mac has two separate partition tables mapping the same underlying physical disk to make the disk look like a MBR or an GPT disk. On Macs older than 2014, the default is to use a Hybrid MBR. If you use any disk management functions in Windows, it converts the underlying disk from GPT to MBR. OS X , and EFI-based OS will not boot from an MBR disk. You need to boot into Internet Recovery - About OS X Recovery - Apple Support - and click on Utilities -> Terminal, run the following commands

diskutil list

gpt -vv -r show /dev/disk0

Copy (Command+C) the output, exit Terminal, start Safari, Paste (Command+V) the output and we can examine it and provide guidance on next steps.

Please do not randomly try moving the Mac disk to other machines, it makes diagnosis difficult.

You have a corrupted GPT. I strongly recommend re-installing the disk back internally (not externally) in the Mac. Find a second hard disk and install OS X using How to install OS X on an external drive connected to your Mac - Apple Support . Upgrade it to match the OS X version on your internal disk, assuming you know the exact version of OS X on the internal disk. Boot from the external disk and install GPT Fdisk from https://sourceforge.net/projects/gptfdisk/  on the external disk.

Please post back when you get to this point.

Please post the output OSX Terminal command

diskutil list

diskutil cs list

Please disable SIP before we can modify the GPT on disk0.

1. Boot into Local Recovery (Command+R) from your external disk.

2. Start Utilities -> Terminal.

3. Type csrutil disable in Terminal and press Enter/Return.

4. Type csrutil status.

5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.
