Hello, On a dual boot machine (one fc32, and one fc34). after I upgraded the fc32 to fc34, I cannot boot on the new fc34. I get failed to mount /boot/efi /boot/efi is shared by both machines Here is the fstab of the fc34 machine # UUID=a5b809ae-61c2-4d67-b0f3-109e99faad39 / ext4 defaults 1 1 UUID=B2EF-0CE4 /boot/efi vfat umask=0077,shortname=winnt 0 2 The /boot/efi seem correct (it is currently mounted by the fc32). blkid |grep B2EF /dev/sdb1: UUID="B2EF-0CE4" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="0fe1d405-6683-456c-a306-140e882e322c" blkid |grep 9faad39 /dev/sda6: LABEL="fedora_rescue" UUID="a5b809ae-61c2-4d67-b0f3-109e99faad39" BLOCK_SIZE="4096" TYPE="ext4" PARTLABEL="OS" PARTUUID="41b9d134-b477-4ef5-8602-15fdc482a51e" What should I do ? It seems that the installer create /boot/efi/EFI/fedora/grub.cfg with search --no-floppy --fs-uuid --set=dev a5b809ae-61c2-4d67-b0f3-109e99faad39 set prefix=($dev)/boot/grub2 export $prefix configfile $prefix/grub.cfg (I could not boot either) Then I run (from the fc32) grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg.new and used this file to boot (by renamed). But I still have the same issue. What to do? It seems that there is a similar issue inb https://unix.stackexchange.com/questions/646150/problem-with-double-fedora-installation-mount-boot-efi-unknown-filesystem-ty Thanks. =========================================================================== Patrick DUPRÉ | | email: pdupre@xxxxxxx Laboratoire interdisciplinaire Carnot de Bourgogne 9 Avenue Alain Savary, BP 47870, 21078 DIJON Cedex FRANCE Tel: +33 (0)380395988 | | Room# D114A =========================================================================== _______________________________________________ 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 Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
