In my For completeness: The new installation of F36 overwrote the /boot/efi/EFI/fedora partition, preventing the old F36 from booting. At this point you could have booted into the new F36, mounted the old F36, chrooted to the old F36, by performing the steps you did from the system recovery below, > I’ve managed to chroot (a very dumb word) thru a LiveUSB session, > with the following commands: > > >>cryptsetup luksOpen /dev/nvme0n1p6 fedora_crypt > >>mount /dev/mapper/fedora_crypt /mnt/ -t btrfs -o subvol=root > >>mount /dev/mapper/fedora_crypt /mnt/home -t btrfs -o subvol=home > >>mount /dev/nvme0n1p5 /mnt/boot > >>mkdir /mnt/boot/efi > >>mount /dev/nvme0n1p1 /mnt/boot/efi > >>mount --bind /dev /mnt/dev > >>mount -t proc /proc /mnt/proc > >>mount -t sysfs /sys /mnt/sys > >>mount -t tmpfs tmpfs /mnt/run > >>mkdir -p /mnt/run/systemd/resolve/ > >>nano /mnt/run/systemd/resolve/stub-resolv.conf (enter 'nameserver > >>1.1.1.1', save) chroot /mnt > > >>dnf reinstall grub2-efi grub2-efi-modules shim This would have fixed the problem, allowing you to boot the original F36, and no longer boot the new F36. The problem is that both F36 installations used the same directory on the ESP, and so collided. There can only be one ESP (EFI partition) per drive, I think that is a requirement of EFI. So, you would have to use either sdboot, or the technique Felix described in a later post in order to boot multiple version of F36 using grub. I don't think either is trivial for a new user of Fedora, but your mileage might differ. _______________________________________________ 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 Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
