Problema de inicialização dupla ao lado do Windows 10

Eu instalei o Ubuntu 16 do DVD, mas ainda assim só obtenho o login do Windows 10. Eu escolhi a opção 'instalar junto com o Windows 10' e deixei o tamanho do disco automaticamente.

Como vejo o Ubuntu no log in?

sudo fdisk -l

Parece que você instalou o grub inadvertidamente na unidade errada ... possivelmente uma partição ou um pendrive.

Verifique se o Grub está instalado na unidade de inicialização específica (provavelmente /dev/sda ). Você pode fazer isso reinstalando o grub com estas etapas:

Inicialize em sua mídia ao vivo (seu disco de instalação do Ubuntu ou pendrive USB). Execute a opção Try Ubuntu . Então vá para um terminal shell e execute estes comandos:

Etapa 1:

$ sudo mount /dev/sdaX /mnt # Make "X" the partition that has Ubuntu installed (i.e. /dev/sda2)

Etapa 2:

$ for i in /sys /proc /run /dev; do sudo mount --bind "$i" "/mnt/$i"; done

Etapa 3:

$ sudo chroot /mnt

Etapa 4:

# update-grub

Etapa 5:

# grub-install /dev/sdX # (x is the hard drive that has linux installed (i.e. /dev/sda)
    update-grub

Agora reinicie o sistema.

Usando o comando $ sudo fdisk -l /dev/sd* no meu sistema mostra:

Device     Boot     Start        End    Sectors  Size Id Type
/dev/sda1            2048  102402047  102400000 48.8G 83 Linux
/dev/sda2  *    102402048  204802047  102400000 48.8G 83 Linux
/dev/sda3       204802048  245762047   40960000 19.5G 82 Linux swap / Solaris
/dev/sda4       245762048 3907028991 3661266944  1.7T 83 Linux

Neste exemplo, o Linux está instalado em /dev/sda1 e /dev/sda2 .

Resolução final

O problema foi resolvido via bate-papo, garantindo que a instalação fosse realizada no modo UEFI e escolhendo Ubuntu na opção de inicialização do Bios.

O Ubuntu apresenta a opção de menu Windows e Ubuntu no menu Grub. Se a opção Bio Boot (ordem) estiver definida como Windows , o sistema inicializará diretamente no Windows. O Windows não reconhece outros sistemas operacionais de instalação.
