mount /dev/sdXY /mnt mount --bind /dev /mnt/dev mount --bind /dev/pts /mnt/dev/pts mount --bind /proc /mnt/proc mount --bind /sys /mnt/sys chroot /mnt grub-install /dev/sdX update-grub exit reboot (https://howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a -ubuntu-live-cd) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848797 Title: After upgrading to 19.10, boot screen shows: "Error: symbol 'grub_file_filters' not found."
