I’ve been having this issue with trying to setup dual-booting on my desktop PC. Made sure that both settings have been disabled but that doesn’t seem to be my problem. When I try doing any sort of install it gets stuck on a gray screen without any menus.
My specs are a Lenovo Legion prebuilt based on intel/nvidia. I managed to get it working once so compatibility shouldn’t be an issue.
Would appreciate any help/advice, thanks in advance :).
