Today I was updating one of the system (Lubuntu) on one of my test partitions. The system wasn't the default one at the boot, but as the grub packages have been updated, after the re-boot I have discovered that it was set as the boot default system...
This bug creates problems even with the updates. At least I have found a quicker workaround here http://superuser.com/questions/376470/how-to-reinstall-grub2-efi All you have to do is booting from the grub menu the *buntu system you would like as the default one and run this command: sudo apt-get install --reinstall grub-efi-amd64 This might sounds obvious, but every time I was searching informations related to grub/uefi I always found instructions for external instruments such as boot-repair. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1056101 Title: grub-efi overwrites an existing grub*.efi file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1056101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
