Dude first of all, thanks for your time, i really apreciate you tried to help me. I already fixed (or at least did something with) my laptop. I'll be honest with you: after being unable to make any progress i got super angry, i restarted the laptop, pressed alt, fn, ctrl, shift and all the fucikng Fs like a maniatic, believe it or not it gave me some options and i troed to proceed as mentiond before. NOTHING worked! It continued telling me to try and try and try untill i decided to fuckn use the option to Restore my laptop and lose my data.... I did it, still gave me couple of troubles but now at least my laptop works fine. Guess i'll just spend couple of hours downloading my stuff again. Is a sad ending but at least I learned a lesson the bad way. Tomorrow I'll buy an external harddrive for all my future data.
Sorry for the long post dude and again, Thank you for time.
