Why won't boot recovery mode? Won't start even from boot usb
i updated my macbook pro to mountain lion few weeks ago. Today it won't boot, when i try, after few minutes (with the apple and wheel) it restarts. If i try to boot in recovery mode, after few minutes there's a voice that says "to choose english language, please press return key". But the screen is stuck with the apple and the wheel blocked.
What can i do? it's the same with the bootable usb.
Thanks in advance
I also tried to reset PRAM, SMC and i did fsck from single mode use with no success
