Hello. Girlfriends Lenovo B50-10 laptop decided to brake a little bit. I think that it was doing windows updates and something went wrong, now it shows that hal.dll is missing. I made a bootable usb with windows on it to try and fix a problem, but now I can't use it because, I think, secure boot is enabled. Opened up BIOS, but there is no way to disable it. Any ideas? Thank You.
