I too have this issue. I enabled the secure boot setting in my computers BIOS and when I saved and exited the BIOS menu, my computer lights up and turns on but my monitor just goes blank after saying no signal powering off. I’ve looked up videos to help and tried almost everything and I’m out of options.
Hi @angelolitnar What is the make and model number of the PC or motherboard if a custom install? What is the make and model number of the GPU card? If you get a display when in BIOS then it may be a video driver problem, as BIOS uses only basic drivers for its display. Try starting the PC in safe mode with networking and check if you get a display. If you do then it is a driver problem as only Windows drivers are loaded and not hardware specific ones.
Something is not compatible with Secure Boot. You need to figure out what and se if there is something you can do to make it compatible. You can start here and see where it goes. https://www.thewindowsclub.com/computer-…
Look up the graphics card make and model to see if it supports secure boot. I’ve seen it happen with older ATI cards like like 2270 or 2450 which simply black out the moment secure boot was enabled. Only way back was to swap the card or clear the CMOS to regain a display.
