Hello to everyone.
I’ve installed Debian (11) and Fedora (37) on the same disk (and I plan to install even Arch) and I would like to boot one of these OSes depending on my needs. The first os that I’ve installed has been Debian (I have used the automatic partition scheme) and then Fedora (even here I have left the Fedora installer to chose how to partition the space left free by Debian). At the moment I haven’t installed yet Arch,because I’m able to boot Debian,but not Fedora and I would like to understand what’s wrong before to do it. Obviously Debian before and Fedora after,taken all the space available on the disk,so I have used gparted to resize their root partitions. While I tried to understand what could be broken,I’ve took some screenshots to show you how the disk is partitioned. The problem is that the Fedora entry does not show on the grub menu even after writing “os probe” from Debian (it’s true using qemu-kvm and even on the bare metal). And it does not boot even using the EFI partition that it creates and that’s different than the EFI partition created by Debian and modified by Fedora on the first partition of the disk. Anyway,I understand that’s hard for you to understand what’s happening without to give a look at the pictures that I’ve got,so here you can :
As you can see below,the fedora installation is not detected :

I hope you can help me to understand how to accomplish this task. Very thanks.
