I want to shift from BIOS to UEFI, my drives are using Master Boot Record MBR, I need to convert them using MBR2GPT.EXE on my Windows 10, the only problem is, that I am not 100% if my motherboard supports UEFI, my motherboard: Gigabyte A320M-S2H V2-CF with BIOS: F40 – AMD AGESA Combo-AM4 18.104.22.168. To shift to UEFI, I have to change the boot mode to UEFI, but I cannot find anything like that in Gigabyte BIOS. All I see is CSM support which is enabled at the moment, and storage boot option which is set to Legacy only at the moment. Does it mean that if I convert my drive to GPT partition and change storage boot option to UEFI everything will work well? Or maybe disable CSM? Or does my motherborad not support UEFI? Many thanks, I cannot find anything on Google.
