Hi! Which tools in which versions did you use?
For example which FORMAT, FDISK...? Let me start by saying the choice for MBR was good: GPT partitions are not visible for DOS. Not sure what the purpose of that EFI partition is, but it is easily possible that Windows had a boot loader on the first disk to boot from the second, affecting both boots. You can tell FDISK to install a fresh MBR boot code, see the command line help of FDISK :-) Of course you also want to mark the partition as bootable and for big disks, you probably want to use FAT32 LBA partitions for FreeDOS.
