What is the size of your SSD, and how much free space does it have?

Also what is the version of OS-X/MacOS are you running currently and did you make sure it was up to date?


The ssd 512 gb

For the osx 345 gb free 35gb

Bootcamp 150 gb

I updated it to os x el capitan 10.11.6

At this point I think you'll need to wipe the drive down and set it up again. One of the risks with running Windows is Trojan's and other nasties that can spill out into the boot sectors. I fear you may have encountered one here.

Go into internet recovery or if you have a OS-X bootable USB drive boot up under it wipe the drive down completely then re-install the Mac OS (get all of the updates installed) then setup BootCamp and then Windows (install all of the Microsoft updates). Don't install any apps yet! As you'll want to install a dual Mac OS-X/Mac OS & Windows antivirus app and make sure its up to date with all of the definition files. Then install your Apps, make sure you've gotten them from the company directly, be careful here with 'Free' apps that are normally paid for as many are infected with spyware.

the problem is if the ssd is connected to the mother board the device will never boot only black screen but if removed it the device can boot and i can select from boot manager


Laser - Is this the original SSD that came with the system? If not that could be your problem. This may not be the correct SSD for your system! If you wipe the SSD when its externally connected (nothing on it) and put it back internally are you able to get internet recovery to work?

You may need this to hold your SSD: OWC Envoy Pro Portable, Bus-Powered USB 3.0 Enclosure For Apple Flash SSDs (June 2013-Current Mac Models) so you can properly wipe the drive.
