[résolu] probleme de démarrage
Bonjour,
Suite à une mise à jour qui s'est mal passée, mon ordi démarre systématiquement avec le memtest, et impossible d'aller plus loin (quand je fais ESC, l'ordi reboot à nouveau sur le memtest). Je ne crois pas être en RAID, et je n'utilise sur cet ordi qu'ubuntu (une version récente, 16.quelque chose...), je n'ai pas de partition windows.
J'ai donc fait une live usb avec boot repair, et voici le rapport boot info :
http://paste.ubuntu.com/24057850/
J'ai essayé la réparation recommandée, mais très vite, il affiche "purger les kernels puis réinstaller le dernier kernel mapper/ubuntu--vg-root (ins)" et bloque là-dessus. Je l'ai laissé travailler une nuit entière, mais pas d'évolution.
Si je reboot la machine, le memtest recommence.
Quelqu'un peut-il m'aider ?
Merci.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda, using the following options: kernel-purge
Additional repair would be performed: unhide-bootmenu-10s
=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (2013MB) !

/dev/mapper/ubuntu--vg-root:Ubuntu 16.04.1 LTS (16.04):Ubuntu:linuxLe support que tu as utilisé pour faire ce Boot-Info est indiqué dans cet autre extrait qui mentionne "Boot-Repair-Disk" :
boot-repair is executed in live-session (Boot-Repair-Disk 64bit 29nov2014, trusty, Ubuntu, x86_64)J'ai expliqué aujourd'hui même dans ce post que Boot-Repair-Disk est merdique. Pour réparer ton Ubuntu malade, je te recommande d'utiliser un support live de Ubuntu 16.04.1 64 bits. Tu peux utiliser cette recette pour réaliser une liveUSB équipée de cette version. Ensuite, tu pourras tenter de réparer avec Boot-Repair suivant le paragraphe 1.2 Installer Boot-Repair depuis une session live (DVD ou liveUSB) de Ubuntu

Re : [résolu] probleme de démarrage
Salut Malbo,
C'est bon, j'ai suivi tes conseils : utilisé un live usb d'ubuntu, installé boot repair, fait une réparation recommandée, et ça a marché, l'ordi redémarre normalement.
Effectivement, l'utilisation d'un boot-repair-disk est à déconseiller vivement.
Merci encore pour ton aide,
Martin.
