Should I run grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg and not grub2-mkconfig -o /boot/grub2/grub.cfg. ?
No: since a few fedora versions, /boot/efi/EFI/fedora/grub.cfg simply redirect to /boot/grub2/grub.cfg.
This I do not understand On the installation which provides troubles (I can only boot through super grub) I have /dev/sdc3 23800324 15253780 7313160 68% / /dev/sdc2 432924 282442 123500 70% /boot
os-prober does not see /dev/sdc3 but in /boot/grub2/grub.cfg I have see set root='hd2,msdos3' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd2,msdos3 --hint-efi=hd2,msdos3 --hint-baremetal=ahci2,msdos3 da1fb213-c138-4711-aba2-76a598506283
which is the installation on sdc3 There is no /boot/efi/EFI/fedora/grub.cfg If I umount /boot and mount /dev/sda3 /boot/efi (sda3 is recognized as a EFI System Partition) sdc3 does not show up in /boot/efi/EFI/fedora/grub.cfg
This seems to indicate that I need to make
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
grub-customize does not show my fedora 40 installed on sdc3 either
Can you describe what disk/partitions you have ?
I guess you have two disks, each with a system and an EFI partition
