please friends, I know there are many that are handled in technology, I made the mistake of misusing the terminal Ubuntu, and I need to please someone who can help me, but slowly, preferably with pictures, many know that not speak English well, and I need a step by step tutorial ( the model is Acer aspire e1-470g-6806), but I need the tutorial step by step and from start to finish. I know it's too much to ask, but please, I lose my job and I have no where to get another.
I need to reinstall everything
PLEASE!!!
