I apologize profusely I am sure if I dig this has been gone over on 100 threads.
I am attempting to fix my son's Nitro laptop from work while he is home. We've tried BIOS , windows recovery and the button on the bottom. I am not technically inclined and I can't let him use my notebook since it is swimming in virus at work all day.
Can anyone walk me through downloading windows 10 and I have read where you have to also download Rufus? If I download will it be obvious what I do from there? 
Thanks In Advance as this is ridiculously embarrassing.
