chroot: falha ao executar o comando ‘/ bin / bash’: Nenhum arquivo ou diretório

1

Para corrigir o grub, tentei seguir os códigos:

sudo mount /dev/sd6 /mnt 
sudo mount --bind /dev /mnt/dev 
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys

Enquanto tenta:

sudo chroot /mnt

mostra " chroot: falha ao executar o comando '/ bin / bash': nenhum erro ou arquivo ".

Por favor, ajude-me a corrigir este problema.

Obrigado antecipadamente.

A saída para sudo lsblk -o name,mountpoint,label,size,fstype,uuid | egrep -v ^loop&&sudo fdisk -l é:
