I have installed Windows 10 with secure boot off and now I want to install Windows 11. So I turned secure boot back on but, only a black screen shows after computer boots.
What I see - I can see POST LEDs passing on the Mobo and fans spinning, it looks like the computer boots but does not give the output.
PC specs - CPU AMD Ryzen 5 3600, MSI MPG B550 Gaming plus Mobo, 16GB RAM, Nvidia GT 710 VGA (this is just for video out),
I searched the internet and found similar questions here and here but, could not find an answer yet. Can someone help me please?

Myabe you can fix it with bios flash button - my mb didn't have button so i didn't try
First thing, you have to connect to Integrated graphics card in your PC and you have to have Windows on USB stick.
When your PC will turn on, the secure boot will be enabling so your BIOS become UEFI not legacy you have to startup setup Windows installation click Shift and F10 the cmd will switch.
