Ubunto UEFI when we have 2 drives with separate boot EFI dirs

Under ubuntu (some of these steps are probably optional)
Need a pass to remove each optional item to streamline steps

mount /dev/sda2 /mnt [mount win10 efi]
mv /mnt/EFI/Boot/bootx64.efi bootx64.efi-origwin10 [backup]
cp -r /boot/efi/EFI/BOOT/Bootx64.efi /mnt/EFI/Boot/bootx64.efi [copy ubuntu bootstrapper to win10 drive]
cp -r /boot/efi/EFI/ubuntu/ /mnt/EFI [copy ubuntu dir tree to win10 drive]
cp /boot/efi/EFI/ubuntu/grub.cfg /mnt/EFI/Boot/ [copy ubuntu boot drive stuff to win10 drive]
cp /boot/efi/EFI/ubuntu/mmx64.efi /mnt/EFI/Boot/ [copy ubuntu boot drive stuff to win10 drive]
cp /boot/efi/EFI/ubuntu/shimx64.efi /mnt/EFI/Boot/ [copy ubuntu boot drive stuff to win10 drive]
