Hello, I can't disable CSM in BIOS. The message appears: "display device does not support uefi graphics output protocol " because my video card "does not support uefi gop". Tried many things but no solution. I want to install Windows 11, but due to this problem I can't disable CSM to enable "Secure Boot". My motherboard is: Steel Legend B450M and my video card is an RX580. If anyone had the same problem and can help me.

So clearly your RX580 is the problem here, the VBIOS doesn't support UEFI.

Some people here may be able to modify the VBIOS, or maybe there are some UEFI capable BIOS'es for your GPU in the TPU GPU database already.

I'm pretty sure SecureBoot is supposed to work regardless of whether CSM is enabled or not.

Edit: And now I'm pretty sure I was wrong :slap:
 
Apenas para ter certeza, execute o GPU-Z e veja se a opção UEFI está marcada.
Acho que o Rufus tem a opção de ignorar o Secure Boot para Windows 11 ao criar um USB inicializável.

Mas, sim, parece estar relacionado ao VBIOS.
Obrigado pela informação. Vou verificar sobre isso.

I know that, the guy is a beast!
 
Boot up using CSM for now, then Open GPU-Z Get a screenshot, then go to the Advanced Tab and then Get a Screenshot of all the options there- meaning click General and change to the next item etc.

Also a picture of the white sticker from the back of the card or on the side of the hestsink helps
 
Just to make sure, run GPU-Z and see if UEFI option is checked.
I think Rufus has an option to bypass Secure Boot for Windows 11 when creating bootable USB.

But, yeah, seems to be VBIOS related.
Yeah, I have used Rufus to install win11 pro on a ASRock Deskmini with 2400G. I haven't experienced any problems with it to date. Little thing is snappy, can brute force 4K youtube, and play older games like Batman Arkham City really well.

ifixit has a easy guide to do it - https://www.ifixit.com/Guide/How+to+install+Windows+11+on+unsupported+devices/160527

Obviously skip the RUFUS download step since it is linked above by @Dan.G
