Finally I got my Laptop working again: - I recovered the EFI System Partition - ran the Boot-repair disk - Let Windows repair its boot loader and got both OS running again. The grub start window is a little bit of a mess now, but at least Ubuntu and Windows 8 are running again without having anything lost.
Tx for your support, I would have prefered to repair the system more "conventionally", but I guess there was no way to do a clean repair...
