MacPro 5,1 Win10 Switch BIOS to EFI?

Is it possible and does it make sense to switch my current BIOS boot to EFI using WinClone on an existing disk? The drive used for Windows 10 is solely used by Windows, but was set up by BootCamp Assistant. Contents were copied from another drive by WinClone several years ago.

It really only affects booting, so I would leave it alone if it is working :slight_smile:
