So basically I have an issue with my system's OS. I can't switch the BiOS mode from UFEI to Legacy. So what I want to do it load in a Windows 10 Media Installation USB into my system Boot Manager. But for some reason it won't load due to the SATA mode. But everytime I switch from RST to AHCI it always goes dark & I need to battery reset (no pinhole). Any suggestions or advice?
