Public bug reported: I have 2 systems installed on ZFS - Ubuntu Mate 18.04.3 - Xubuntu 19.10
For the coming period I like to keep one ext4 installation, so I did do a fresh install of Ubuntu 19.10 on the ext4 sda1 partition. I installed zfsutils-linux and rebooted. Afterwards I did run "update-grub" and "grub-install" and both Ubuntu systems on ZFS were detected looking at the output. In /boot/grub/grub.cfg all 3 systems were present. After reboot the menu still did not show, grub did not detect the multi-boot. Only after changing /etc/default/grub the boot menu appeared on the next boot. As far as I understand the menu should appear by default in a multi-boot situation. ** Affects: zfs-linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843340 Title: Boot menu not displayed for multi boot with ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1843340/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
