Dual booting - Windows 10 will not boot with CSM disabled?

Hi,

I've just reinstalled my Windows 10 yesterday and i'm not able to boot into it while CSM is disabled on BIOS.

Thing is, to boot into Catalina i have to use Disabled CSM function on BIOS.

My windows 10 is installed with UEFI on GPT partition.

How can i fix that? I understand that usually this issue from legacy installations but i'm not sure.

Windows indicates 100% that i'm using UEFI installation but maybe something has went wrong in process. There's no other explanation. I'm using two different EFI partitions (1 for opencore and 1 for windows10).

Thanks
