Ubuntu 17.1, Busybox au démarrage et initramfs

Bonjour à tous,

J'utilise Ubuntu depuis peu, 100ù sur mon disque dur. Au bout de quelques semaines d'utulisation, je n'arrive plus à démarrer ubuntu, sans raison évidente, et tombe sur ce terminal Busy Box  (initramfs)

J'ai tout réinstallé une première fois, tout marchait comme avant, et là rebolote après plusieurs semaines d'utilisation.

Boot-repair ni fait rien...

Voici le lien http://paste.ubuntu.com/26356756/

Sur la première ligne No known boot loader is installed in the MBR of /dev/sda.

Le problème vient-il de là?

Lorsque je veux réinstaller ubuntu, il ne me propose que d'effacer le disque et de réinstaller, à priori il ne reconnaît pas l'ancienne  installation?

Merci d'avance!

Re : Ubuntu 17.1, Busybox au démarrage et initramfs

Bonjour

tepeu a écrit :

Bonjour à tous,
. Au bout de quelques semaines d'utilisation, je n'arrive plus à démarrer ubuntu, sans raison évidente, et tombe sur ce terminal Busy Box  (initramfs)

Voici le lien http://paste.ubuntu.com/26356756/

Sur la première ligne No known boot loader is installed in the MBR of /dev/sda.

Le problème vient-il de là?

Lorsque je veux réinstaller ubuntu, il ne me propose que d'effacer le disque et de réinstaller, à priori il ne reconnaît pas l'ancienne  installation?

Merci d'avance!

Lorsque tu as l'expression busy box (initrmfs) qui s'affiche, elle doit être précédée de quelques lignes d'erreur qui indiquent la raison.
Soit tu recopies, soit tu fais une photo que tu postes dans un site de partage d'image et tu transmets l'url générée.

Ton bios étant positionné pour booter en EFI, il est normal qu'il n'y ait aucune structure de boot dans le MBR

Comme tu avais pris la décision d'installer en mode crypté dans du LVM, il est normal que l'installateur ne retrouve rien.

Ce que tu décris comme problème me fait penser à un disque qui est malade.
En conséquence, avec le support d'installation, transmets-nous un rapport smartctl paragraphes 1 et 3.1 de https://doc.ubuntu-fr.org/smartmontools

Re : Ubuntu 17.1, Busybox au démarrage et initramfs

Mon modèle:
ASUS E403S, 2 G de RAM, HDD 32 G, CPU intel dual-core N3050, année 2016

Je ne comprends pas très bien l'EFI, aurait-il fallu que je ne l'installe pas dans ce mode ?
Le mode crypté du LVM ? Késako ? A éviter à la prochaine installation?

Concernant smartctl, voici la réponse :
smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.13.0-16-generic] (local build)
Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org

/dev/sda: Unknown USB bridge [0x05dc:0xa838 (0x1100)]
Please specify device type with the -d option.

Pourquoi USB ? Je ne comprends plus mon partitionnage.

J'aurai besoin de quelque chose de stable sur mon ordi, même si cela doit passer par une réinstallation, je pense que je partionnerai /home à part la prochaine fois, ça m'évitera des pertes inutiles.

J'envoie le message d'erreur Busybox après le redémarrage.

Merci à vous !

Re : Ubuntu 17.1, Busybox au démarrage et initramfs

Résolu!
1ere étape j'ai réinstallé en respectant /home pour ne pas tout perdre.
Alors au démarrage d'ubuntu ce message apparait avant Busybox:
/dev/mapper/ubuntu--vg-root
Failure: File system check of trhe root file system failed
The root file system on /dev/mapper/ubuntu--vg-root requires manual fsck

J'ai donc tapé fsck.ext4 -v /dev/mapper/ubuntu--vg-root
Je ne sais pas bien à quoi ça correspond mais ça a fonctionné, sans perte de document, mais perte de certaines application (zotero, spotify).

Ma question maintenant, c'est comment éviter que cela se reproduise ?

Merci

Bonsoir
Pour le boot-info, je ne comprends pas très bien le problème mais je fais confiance à Malbo
==>Tu as certainement installé la version 17.10 qui est incapable de faire de l'affichage sur les écrans sans faire un bidouillage monstre..
Pour le rapport, smartctl, si j'avais bien lu ton premier boot-info, j'aurais réalisé que tu n'avais pas de disque mais un MMC pour lequel il n'y a pas d'outil  de suivi  de leur qualité. Désolé de t'avoir demandé l'impossible..
