two days ago, i installed fedora jam 39 on an external drive. This runs successfully.

BUT after restart and plug off the external drive Grub from my internal drive does not show my fedora39 installation.

You installed Fedora on the external drive, but you also have an installation on the internal drive?
Yes this is correct. If i plugin the drive, fedora jam is correctly booting.

When you installed to the external drive, it replaced the Fedora entry in the EFI boot list to point to that instead of the internal drive.

Yes i understand that.
But unconnected drive and running grub2-mkinstall i thought, that an Entry with my fedora 39 from infernal disk is generated. But it doesnt.

You should not be running that command on a UEFI system. You need to fix the UEFI boot entry.

it seems, that the recovery scripts from the different tutorials (mostly in end grub2-mkinstall) are not recognizing the fedora39 installation. i do not understand why.

Those are for legacy systems, not UEFI.

Go into the BIOS and check the boot list.  I'm wondering if you have a Debian entry that is being used.  You can also add another Fedora entry that points to the internal hard drive.

Yes i have an Debian Entry and a Windows Bootmanager, but no fedora.
Before installing fedora Jam i Bad three: Debian, Windows and fedora. And fedora was in the first place, so it starts from there. But how could i insert a New Entry? I think, the BIOS does not recognize the fedora one, or it is not there. If i can install the Boot loader for fedora, then it will work again. But how could i do that?

I assume that the Fedora one currently points to the external drive, so it's possible that it's not listed because the drive isn't there.

Run "grep efibootmgr /var/log/anaconda/storage.log"
Copy the long line and run it (as root or use sudo), but change the "Fedora" name to "Fedora2" or something so it will be a different entry.

e.g. on my system it is:
efibootmgr -c -w -L Fedora -d /dev/nvme0n1 -p 1 -l \EFI\fedora\shimx64.efi

So I would run:
sudo efibootmgr -c -w -L Fedora2 -d /dev/nvme0n1 -p 1 -l '\EFI\fedora\shimx64.efi'
