I inherited a laptop from my dad. My grandmother made me buy it because he didn't have a will.

I think she crashed it.

We i turn it on it says..

Selected boot image did not authenticate.

Press enter to continue. 

I also noticed the battery is gone and it has to be plugged in to use. 

My father always has the best electronics. 

Please tell me i can save it.
