27;s the solution for the EFI boot interface, use EFI variables.
For the BIOS boot interface, I'm still clueless why it doesn't work. However,
I'll leave it at that.
Thanks to everyone who helped!

Hello Steve,
thanks a lot for the tip! However, I'm a complete novice when it comes to
running custom firmware in QEMU. I just tried the following:
1.: Download the latest EDK2 release from Github:
https://github.com/tianocore/edk2/archive/refs/tags/edk2-stable202302.tar.gz
2.: Extract the OVM
By the way:
The disadvantage of using EFI is that it doesn't work in QEMU, i.e. the
following will not show a GRUB command line:
sudo qemu-system-x86_64 -accel kvm -smp 2 -m 2G /dev/sda
The same thing works for the BIOS boot interface, however (as in my original
recipe).
I apologize for the formatting in my last post, I don't know what happened. And
many thanks for your help!
I checked my partition table using "sudo parted /dev/sda print" and it didn't
show any flags for partition 1 (the "init" partition). Therefore I manually set
the flags using "sudo parted /

There are a few things I forgot to say:
The recipe I posted earlier is executed on a system installed on the external
drive /dev/sdb, which I call the installer system. It is also a Debian system,
with the recipe's dependencies installed. To reproduce the issue (if you want),
I suggest using a
do it using command line utilities like
debootstrap and grub-install.
Any help would be very appreciated.
