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
