Hello My y50-70 screen is broken and there is no compatible version (4K) available for it. I cannot boot to the OS for some reason, can anyone help me and tell how can I get to bios on an external monitor with HDMI or ... also, downgrade bios from v3.03 to v1.14 but it not help, which I think is maybe because of secure boot or ... , if it just boots from a USB device that can help and let me back up my data & repair the grub. Also, there is no video (photo) of its boot menu to help me do it blindly.
