I do not fully understand this, but Chris Murphy explained that there is only the *one* /boot/efi/ per system and only *one* entry for fedora in /boot/efi/EFI/. As I understand it, this is because of the efi standard. So, if booting more than one version of fedora using efi, the grub.cfg in /boot/efi/EFI/fedora has to be changed to point to the correct /boot/loader/entries for that fedora. You could have several versions of the grub.cfg and just swap them to boot other versions. Messy. Apparently, this can be solved by using systemd bootctl, an alternative to grub2, but fedora does not use that and I haven't investigated further. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
