For a workaround, symlinking x86_64-efi to i386-pc works: $ sudo mkdir -p /mnt/root-tmp $ sudo /dev/<your-root-partition> /mnt/root-tmp $ cd /mnt/root-tmp/usr/lib/grub $ sudo ln -s x86_64-efi i386-pc
Then re-run the command to install grub-efi-amd64-signed. Hope this helps. -- Duong -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1277865 Title: Cannot install Ubuntu 14.04 on EFI hardware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1277865/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
