So the entries in /dev/sda9/boot/grub/grub.cfg are correct in any 3 cases.
But always menu 0 from /dev/sda9/boot/grub/grub.cfg becomes executed after
reboot.
I guess, the problem could be, that I include another menu in a top level menu.
So I will try to work with submenu logic.
So now I have replaced the "menu" commands by "submenu" in the primary grub.cfg.
Unfortunately this doen't help too.
Check environment variables during boot
- are they set as you expect them?
How can I display variables in grub screen, before Linux is booted?
Thanks for your hints,
