Hey guys, just like the title says, I'm trying to make a custom Windows 10 install media that includes both architectures in the same installation media, but that it can boot systems in both legacy and uefi modes. Obviously, I'm using the x86 distribution as base and I made the custom install.wim just fine, no problems there. But if I leave it like that, I can only boot both architectures in legacy mode. So I grabbed the bootx64.efi file from the x64 iso and put it in the x86 distribution, next to the bootia32.efi file and no luck either. Is there something I'm missing? Maybe some more file(s) from the x64 distro that need to be copied over to the x86 distro? NOTE: I'm trying to install from a USB formatted in FAT32, just like @Enthousiast recommended, no Rufus or any extra software.
