I use a USB stick in multiboot configuration as the installation medium. This means that there are several Debian ISO images as well as ISO files from other Debian-based distributions in one folder.
Booting from certain ISO images via GRUB also works, but the Debian installer's auto-detection of the installation medium cannot handle this. For example, it uses the first Debian-like ISO file that it can find in the folder.
This can be an old Debian version or an image of Ubuntu, for example, but not necessarily the exact Debian version for which the installer was written and which was just booted.
The two screenshots show the problem and the point where the auto-detection of the installation medium fails.
My grub.cfg for the multiboot USB stick looks like this in short. It's for grub version 2:
What i need is a workaround for the autodetection. I just want to tell the installer to use ISO image file /images/debian-12.7.0-i386-netinst.iso
