Hey guys, im pretty new to computers so sorry if this is a dumb question. I recently Factory resetted my Computer because it was getting slow. It went good until my Computer went off because the power cord fell out.I then put it back in and it said that a error hapenned and that it needed to restart but when i pressed ok it just looped back to the error. I looked on the internet and it said to change somwthing in regedit to work. I did that and it was gone , but then my PC started rebooting and basically got into a boot loop.the weird thing is that if i let it load, it shows me for a sec that windows is downloading ,then boots up again. I also wanted to mention that my friend downloaded for me windows 10 whitout a usb or CD.Can anybody help me?
