=================== Advice displayed in case of recommended repair

 Por favor, desabilite SecureBoot no BIOS. E tente novamenteDeseja continuar?

=================== Final advice in case of recommended repair

 Por favor, não esqueça de fazer sua inicialização de BIOS no arquivo sda2/efi/.../grub*.efi!

 Os ficheiros de inicialização de [o SO atualmente em uso - Ubuntu 14.04.1 LTS] encontram-se longe do início do disco. A sua BIOS pode não os detectar. Pode voltar a tentar após ter criado uma partição /boot (EXT4, >200MB, início do disco). Isto pode ser feito via ferramentas como gParted. Depois seleccione esta partição através da opção [Partição /boot separada:] de [Reparador de inicialização]. (https://help.ubuntu.com/community/BootPartition)

 Talvez você queira tentar novamente depois de ativar a opção [Fazer o backup e renomear os ficheiros EFI Windows].

=================== Default settings

 Recommended-Repair
 This setting would purge (in order to sign-grub upgrade version) and reinstall the grub-efi-amd64-signed of sda5, using the following options: upgrade-grub       sda2/boot/efi,
 Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot
