Answer 1

You can use the most general dd in GNU coreutils. Or maybe partclone.fat (and partclone.restore) in partclone will gives you a smaller image.

I am not sure if it's really useful to make a dump of the EFI System Partition though. You can recreate it with diskpart and bcdboot (by booting into the command prompt of a Windows installation cd/usb or so). The dump may not be useful for you since the BCD Store records inside may not apply anymore.
