The files in this package are specific to GRUB 2, and would break GRUB Legacy if installed on the same system I can "fix it" temporarily doing grub-install /dev/sda but next windows reboot it fails again. I have forced windows to use "\EFI\ubuntu\grubx64.efi" so I am not sure if grub2 is to blame, but on ubuntu 19.04 this seemed to work correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1839317 Title: Grub fails to chainload the Windows Boot Manager on aarch64 laptops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1839317/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
