Démarrage impossible sour Ubuntu 16.04.LTS

Je ne suis plus en mesure de booter sur Ubuntu 16.04LTS et après avoir essayer de démarrer avec le mode sans échec et avoir suivi les différentes recommandations de la page : https://doc.ubuntu-fr.org/reparer_ubuntu je suis manifestement bloqué.

J'ai voulu faire de la place parce que mon SSD commence a être un peu trop plein et j'ai supprimé quelque logiciel normalement non essentiel depuis la logitech. J'ai peut être supprimé le logiciel "video" de base d'ubuntu car j'utilise VLC. J'ai également lancé une mise à jour de ubuntu 16.04.03 depuis la logitech.
d'habitude je ne lance jamais de mise à jour depuis la logitech et je mets à jours mon système soit via la console soit via l'utilitaire de mise à jour qui ce lance automatiquement.
Je ne sais pas si la source de l'erreur provient de la mais en tout cas je suis bloqué.

Je ne pense pas que le problème ce situe au niveau du grub car j'ai utilisé boot-repair et j'ai l'impression qu'il n'y à pas de problème à ce niveau.
A la fin de l'utilisation de boot-repair j'ai obtenu un liens vers des log de boot-repair, voici le résultat : http://paste.ubuntu.com/p/PmMM7vxyKP/

J'ai pris différentes images en screen shoot pour essayer d'identifier le problème :
Tout d'abord quand je démarre en mode normal au bout d'un certain temps j'obtiens un écrins noir comme cela :
http://pix.toile-libre.org/?img=1528908358.jpg

sdb5 c'est mon SSD ou est installé Ubuntu et qui pose problème.

J'ai essayé de différente manière me mettre à jour mon système depuis la console root du démarrage en mode recovery mais la il semble que je ne puisse pas accéder à internet pour faire les mise à jour.
Je me suis logué sur le shell tty2 grâce à mon login habituel puis j'ai exécutés les commande sudo apt-get update && sudo apt-get upgrade La il semble que tu se passe normalement mais cela ne semble ne pas résoudre le problème.

J'ai également créer un live-usb qui est indiqué comme permettant de résoudre les problèmes depuis un mode graphique mais après avoir lancé les mises à jour rien de mieux. J'ai l'impression que les mises à jours son cependant faite pour le live-USB et non pour ma session ubuntu de mon SSD.

J'ai réussi à prendre des images montrant des erreurs comme ici :
http://pix.toile-libre.org/?img=1528907954.jpg

Mais je ne comprend pas ce qu'il faut que je fasse. J'ai cherché différentes choses sur le forum et sur le net mais je comprend pas grand chose et je voulais éviter de faire trop n'importe quoi.

Un autre image pouvant certainement servir :
http://pix.toile-libre.org/?img=1528908311.jpg

En espérant que qqn pourra m'aider.
J'ai envisagé de réinstaller ubuntu mais même en copiant toute mais donner je pense que je vais me retrouver à perdre des logiciels installé ou autre. Dans la mesure du possible j'aimerais bien pourvoir tout réparer.
Merci.

=================== Recommended repair
The default repair of the Boot-Repair utility will purge (in order to enable-raid) and reinstall the grub2 of sdb5 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair will be performed: unhide-bootmenu-10s

Vous pouvez maintenant redémarrer votre ordinateur.
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdb (ATA Crucial_CT256MX1) !

Les fichiers de démarrage de [Ubuntu 16.04.4 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Réparateur de démarrage]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)

J'y vois la mention "linux_raid_member". Moi je n'y connais rien en RAID mais il y a des contributeurs qui s'y connaissent et qui devraient pouvoir t'aider.

Re : Démarrage impossible sour Ubuntu 16.04.LTS

Merci de ta réponse,

Pour le coup je pense pas du tout que le raid soit la source du problème.
Mon raid constitue une partition à part sur lequel n'est pas installé le système.

Le problème concerne la partition sdb5 (mon SSD) sur lequel l'OS est installé.

Je n'ai pas de propositions à faire pour tenter de trouver l'anomalie (c'est trop compliqué pour mon petit niveau). Si personne ne sait t'aider ici, je te suggère de faire une réinstallation suivant la doc Comment réinstaller Ubuntu ?.
EDIT : attention, la version à réinstaller est 16.04.1 64 bits dont le fichier ISO (ubuntu-16.04.1-desktop-amd64.iso) est à télécharger ici : http://old-releases.ubuntu.com/releases … -amd64.iso (si tu prenais celui du site de téléchargement, tu aurais la version 16.04.4 équipée du noyau 4.13 alors que la version 16.04.1 vient avec le noyau 4.4, celui qui est dans ton install actuelle)

Est ce que quelqu'un aurait une idée pour faire avancer les choses ?

N'y a t'il pas un moyen de faire la mise à jour de mon système depuis la session live-usb ?

Merci

Bonsoir
Dans un premier temps, trouves le moyen de mettre des ###### au début de la dernière ligne du fichier  /etc/fstab. C'est celle qui décrit le raids
Car dans la première photo on voit que quelque chose est mis sur disable


Utiliser REFIND au lieu du GRUB https://doc.ubuntu-fr.org/refind . Aidez à vous faire dépanner en suivant le guide
