there is a package with the resuce-grub-files that brought me perfectly to a emergency-drop-in GRUB shell from /dev/sda. now I used grub-customizer here but doesn't find the debian one at all! gonna try with some Gentoo as rescue-system again!
Conclusion: Q4OS is a *good* live-system to be configured easily, could keep me going!
IMO the OsX installation is definitely more 'intelligent' concerning startable boot-partition (being done in the beginning, not as a last step).
so, writing from arch now as end-conclusion.
