No Bootable device ? Alt - option not work

Hello

I have a Pro retina late 2012 and turned under windows with bootcamp.

After a reboot I got the message more or less classic

No bootable device - insert boot disk and press any key

So I tried to press option nothing happens, starting with cmd + R, cmd + alt + R, Shift nothing works

I tried resetting NVRAM that does not work

I have at startup chime sound mac and then 30/40 seconds after the message

Only the SMC reset seems to work, but so far it does not change

I tried with an external keyboard does not change ca

It was controlled it not took water, the screen works even externally

I reinstalled mac osx from another without problem in usb but I ssd presents the same mistake in the retina.

Or that the intrigues me and that if I start the mac without ssd he does his mac and then the screen goes blank with the backlight turned on but it does not display the message

I do not know what to do anymore

I appeal to you to offer me solutions to test

thank you in advance

1. Does OS X Boot normally?

2. Was Windows Automatic Update enabled?

3. What was the reason for the Reboot? Were you switching from OS X to Windows or Windows to OS X?

It was controlled it not took water, the screen works even externally

Are you saying your Mac was damaged or had water spilled on the laptop?

1. Can you shutdown your Mac, start it back up, and hold the Alt/Option key and boot into OS X?

2. If that does not work, then How to install OS X on an external drive connected to your Mac - Apple Support and boot from this external disk to help diagnose the issues with your internal disk.

Please run the following two procedures and try again.

Resetting the System Management Controller (SMC) on your Mac - Apple Support

How to Reset NVRAM on your Mac - Apple Support

Also, do you have a second Mac? Can you also try a Boot in Safe Mode (Command+S)?

Take out the internal hard drive using https://www.ifixit.com/Guide/MacBook+Pro+15-Inch+Unibody+Mid+2012+Hard+Drive+Rep lacement/10761 and put the external disk that you have OS X installed (if it is a SATA disk) and try to boot from this drive.

Also, if you hold the T key, do you see a screen with a Firewire logo? If the firmware was replaced by something different then Apple firmware, some of your keys do not work.

It's the retina 13 i already boot on the ssd osx installed under with my other mac and it work great but on this one i got the error

Do you think it could be an error on the SMC and i will need to "reinstall the firmware" without osx .. ?

Holding T change nothing again

Was your OSX SSD connected to the SATA bus?

If the original owner replaced the firmware on the Mac, then you will need to put the latest Firmware on it. Can you run Apple Hardware Test on it?

This expected. The Apple Bootmanager recognizes the USB as a GPT with OS X to boot from. On the bad Mac there is not such BOotmanager, since you cannot get even Alt to work. You must connect the OS X disk to the internal SATA bus.

The firmware is a non-Apple firmware. Unless you connect to the SATA bus, it is unlikely to work. Even with the SATA connection it may or may not work.
