[Bug 1774753] Re: O pacote 'grub-efi-amd64-signed' falhou em instalar-se dentro de / target/. Sem o carregador de inicialização GRUB, o sistema não incializará.

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the installer in EFI mode. You either need to boot the installer in bios
mode, or partition the disk using GPT and set up an EFI system partition
to install in EFI mode. This will be done for you if you choose the "use
entire disk" guided install option.

Title:
  O pacote 'grub-efi-amd64-signed' falhou em instalar-se dentro de /

  incializará.

Bug description:
  Tinha windows 10 instalado juntamente com o ubuntu 16.04. O windows apresentou problemas e decidi formatar e deixar apenas o ubuntu. Inicialmente tentei instalar o 18.04 e sempre quando vai instalar o grub2 apresenta o erro descrito "O pacote 'grub-efi-amd64-signed' falhou em instalar-se dentro de / target/. Sem o carregador de inicialização GRUB, o sistema não incializará."
  Tentei então reinstalar o 16.04 e apareceu o mesmo erro no mesmo ponto, ao instalar o grub.
