Désolé pour la taille des photos, j'ai fait en direct.
Je n'ai pas de fichier dmesg, qui devrait se trouver dans :
/var/log/
Contenu du fichier fstab, je ne vois rien en lecture seule
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# systemd generates mount units based on this file, see systemd.mount(5).
# Please run 'systemctl daemon-reload' after making changes here.
