From my understanding, no, it is a restriction of efi. Your manual workaround is the only way to get what you want using grub2 as your bootloader. If you switch to systemd-boot, my understanding is that this would be possible, but requires significant changes to the boot process. I considered going to systemd-boot, but decided it was to much work for no real gain, so will stick with grub2. I also didn't like how it seems to put more on the vfat filesystem; I would rather use native linux filesystems as much as possible. When I install my second fedora uefi system, I will also give it its own /boot/efi partition, like you have. But, when I want to boot the other version, I will use the boot menu that the efi firmware provides to select the other /boot/efi I want to use, the one for that version. Another workaround that will work for me because I will only rarely boot into the older Fedora. I keep it around for troubleshooting the current version if something goes wrong. It is known to work, has all the software I want, and is familiar, so easier than booting a rescue version. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org 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@lists.fedoraproject.org
