Getting BOOT MISMATCH! and BOOT FAIL! on boot

Hi all! Fixed the resolution problem I booted and it said:

BOOT MISMATCH!

BOOT FAIL!

​

and I can't get it to work even though I found that the OpenCore.efi is there.

Here is my EFI.

I'm using legacy boot and I'm trying to boot into macOS Big Sur.

Here are the specs:

CPU: Intel Core i5-560

GPU: AMD Radion 4500

RAM: 8GB DDR3

​

Thanks in advance.
