I have lenovo ultrabook ( intel i5, 500GB, 4 GB Ram ) that came with windows 8 THis was OEM version without any cd key. I always installed updates as they were released I had 8.1 , 64 bit last when I upgraded to windows 10. That was some months ago
Till ate Windows 10 was working Ok type for all applications but Internet explorer. That was damn slow. I tried other chrome firefox but they were all slow.
I tried reset option and now the laptop is stuck in REset loop.
I have another Lenovo yoga laptop with Windows 10 working . Can someone help me how to break the Reset loop and restore windows 10
