I had previously updated my HP laptop to windows 10 from windows 7. I never had a problem because I bought another computer and did not even turned it on so I did not know there was a problem, although I noticed it to run slower. Anyways today when I decide to use it, I'm stuck on the "Automatic Repair couldn't repair your PC" message. I have done everything I've found online and still it doesn't work. I tried loading the computer under windows 7 and it will load up until chosing a user then it takes forever and will give me a black screen that gives me a message about not having the complete windows program (something like that). I do not know how to uninstall windows 10 or do anything else if it doesn't even get me to windows at all. I have some files (videos) that I don't want to lose, otherwise I would not mind reseting the whole computer. Help?!
