Hi. Need help on how to fix my laptop. At first it automatically upgraded to windows 10. And due to a beta version new update was requested but it wasn't successfully installed. Then when I put it to sleep mode I want to use it back but it keeps on going to automatic repair start. I tried to restore it but it wasn't a success. Then I ask my friend to have it fix when he return it back to me become no Operating system found. What shall I do?
