Problème démarrage

Bonjour.

Une question de la part de quelqu'un qui ne comprend rien à l'informatique...

Mon ordinateur portable a planté il y a quelques mois. La seule possibilité que j'ai trouvée a été d'installer Ubuntu : après quelques tâtonnements et recherches j'ai opté pour Xubuntu. J'en ai été très content (et très heureux de découvrir que le gratuit était plus convivial que le payant...).

L'ordi a de nouveau planté. J'ai réinstallé. Il a encore planté (je l'ai laissé tourner sur batterie et il s'est éteint...) : et là, avant de réinstaller j'aimerais bien comprendre...

Au démarrage :

Échap :

Phoenix SecureCore Tiano(TM)
…
….
…diverses infos….

System BIOS shadowed
Video BIOS shadowed
BIOS Version : 62CN34WW
…
…

*Ubuntu
Options avancées pour Ubuntu :

       --> e

         GNU GRUB version ... .... ....
         setparams 'Ubuntu'
         ...
         ...
         
       c-->

         grub>

Les autres possibilités m'amènent à "grub>" ou Busybox.

Je ne sais absolument ce que tout ce que je viens d'écrire signifie, mais serais heureux d'avoir des éclairages, de l'aide.

Merci.

J'ai réinstallé. Il a encore planté (je l'ai laissé tourner sur batterie et il s'est éteint...)

Au bout de combien de temps (à la louche) il a planté après que tu l'aies réinstallé  ?

Re : Problème démarrage

Bonjour, et merci de vous intéresser à mon cas.

Je dirais entre 15 jours et 3 semaines.

Re : Problème démarrage

Je te prie de faire un Boot-info depuis une session live de Ubuntu et de donner l'URL de ce Boot-info dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file rename-ms-efi


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda (750GB) disk!


=================== User settings
The settings chosen by the user will not act on the boot.

Je ne vois pas d'anomalie dans ce Boot-Info.
Je te suggère de contrôler l'état de ton disque dur en tapant la commande suivante dans un terminal :

sudo smartctl -a /dev/sda

Tu donneras le retour utilisable de cette commande dans ta réponse.
EDIT : si le retour est "sudo: smartctl : commande introuvable", c'est qu'il faut installer le paquet smartmontools. Cela se fait en passant la commande suivante :

sudo apt install smartmontools

Après cette installation, tu pourras repasser la commande "sudo smartctl -a /dev/sda" et faire ce que j'ai indiqué pour le "retour utilisable" de cette commande.

Re : Problème démarrage

La ligne suivante indique que ton disque est nase :

197 Current_Pending_Sector  0x0032   100   100   000    Old_age   Always       -       22

Elle signifie qu'il y a 22 secteurs du disque dur qui sont en attente de ré-allocation. C'est un signe très sérieux de dégradation de ton disque dur. Tu devrais remplacer ce disque dur mais si tu décides de le conserver, prends bien soin de faire régulièrement tes sauvegardes de données et surveille ce critère "197 Current_Pending_Sector" pour voir si le nombre de secteurs augmente. Surveille également le critère "5 Reallocated_Sector_Ct" : il indique actuellement 0 secteur ce qui est parfait mais il pourrait lui aussi augmenter parce qu'il y a une sorte de vase communiquant : les secteurs en attente de réallocation peuvent passer dans le godet des secteurs ré-alloués.

Fab123

Re : Problème démarrage

Eh bien grand merci malbo pour cette expertise, ces conseils et ces explications (même si je suis loin de tout comprendre). Je vais bien évidemment suivre tes conseils à la lettre. Une dernière chose s'il te plait : quel est selon toi le meilleur moyen de se familiariser avec l'informatique (des composants aux langages etc.) ?
Merci encore et bonne soirée.

PS : et merci à nam1962.

Re : Problème démarrage

quel est selon toi le meilleur moyen de se familiariser avec l'informatique (des composants aux langages etc.) ?

Il faut avoir des emmerdes avec son ordi. L'idéal, ce sont les ennuis matériel. C'est justement ce qui t'arrive, chanceux.

Fab123

Re : Problème démarrage

:-) Vive les emmerdes alors...et du coup à un de ces jours !

Re : Problème démarrage

Bonjour !

Que penses-tu de ceci : http://linuxfr.org/users/zezinho/journa … defectueux

Merci.

malbo

Re : Problème démarrage

Dans le lien que tu as indiqué, je ne suis pas compétent pour affirmer que ça ne sert à rien de faire ce qui est proposé dans le post #1. Mais à mon avis, la dégradation va continuer. C'est un peu comme passer un coup de peinture sur la rouille. Je suis d'accord avec le commentaire posté par Bruno le 15/02/15 à 07:03 : "Personnellement quand j'ai un disque qui commence à présenter des secteurs défectueux, il est immédiatement ré-alloué à la déchetterie."

Fab123

Re : Problème démarrage

Merci. En fouinant (dmesg) j'ai trouvé 3 adresses de secteurs (sur 22 défectueux) qui présentent l'erreur décrite dans le lien : I/O error, dev sda... Et la réponse à hdparm --read-sector xxx /dev/sda est la même pour les trois : reading sector xxx: succeeded suivi d'un tableau de 0000 (8 colonnes X 32 lignes).

Selon toi, ça correspond à "On peut vérifier que c'est bien ce secteur qui est illisible" ?

malbo

Re : Problème démarrage

Je ne suis pas du tout connaisseur dans ce genre de manip et je n'ai pas envie de m'impliquer là-dedans. Si personne ne sait te répondre ici, tu peux créer une nouvelle discussion sur ce sujet spécial de ton disque dur et ses secteurs défectueux. Je pense que la rubrique où il y aurait des experts dans ce domaine est "Autres logiciels et problèmes généraux" ou bien la rubrique "Autres types de matériel".
