[resolu] je n'arrive pas a reinstaller ubuntu

Bonjour à tous,
J'ai un PC portable Acer E15, avec windows8 préinstallé. J'avais installé ubuntu 16.04 en dualboot il y a plusieurs années, tout fonctionnait même si je ne faisais jamais de mises à jour. Suite à un problème mineur sur ubuntu, on m'avait conseillé d'installer la version 18.04. Ma connexion internet étant très lente, on m'a fait un cd bootable, qui a planté au 3/4, et au reboot plus rien ne marchait. J'avais donc décidé de tout formater et repartir à neuf. Et les problèmes commencèrent, j'ai maintenant au démarrage :
"default boot device missing or boot failed
Insert recovery media and hit any key
then select "boot manager" to choose boot device or to boot recovery media"

Juste touche "OK" et on arrive sur "boot manager" avec :
Boot option menu
1. ubuntu16043
2. ubuntu

Je choisis option 2 et introduction live ubuntu sur clef USB

Ecran suivant : GNU GRUB version 2.02~beta2-36ubuntu3.12
avec choix :
try ubuntu without installing
Install ubuntu
OEM install (for manufacturers)
Chek disc for defects

Je choisis checdisk, et obtiens à la fin : "errors found in 1 files"
press any key to reboot

ce que je fais avec clef usb et au boot je lance "install ubuntu"
- Type d'installation, je choisis "effacer le disque et installer ubuntu"
"les tables de partitions des périphériques suivants seont modifiées : SCSI1 (0,0,0) (sdb)
les partitions suivantes seront formatées : partitions 1,2 et de type ESP, ext4, swap"

A la fin de l'installation terminée OK, j'enlève la clef et redémarre : je retombe sur le même message :
"default boot device missing or boot failed
Insert recovery media and hit any key
then select "boot manager" to choose boot device or to boot recovery media"

J'ai essayé plusieurs fois de formater le disque avec gparted, soit à partir du live de la clef USB, soit avec gparted sur une clef USB bootable.
J'ai aussi essayé avec des commandes console :
sudo swapoff -a
sudo dd if=/dev/zero of=/dev/sdb
mais le résultat est toujours le même.

Avez-vous une solution ? mais étant donné que je suis vraiment newbie avec linux (proche du nul), merci de m'expliquer avec assez de détails.

Merci d'avance pour votre aide

La commande sudo dd... a effacé la totalité du disque dur (physique) sdb. J'espère que tu savais ce que tu faisais en tapant cette commande. On appelle aussi dd le destructeur de données

Re : [resolu] je n'arrive pas a reinstaller ubuntu

comme je n'avais plus rien sur le disque, je voulais vraiment repartir à zéro. Apparemment, il y a un secteur qui contient des données, et que je n'arrive pas à effacer.

Re : [resolu] je n'arrive pas a reinstaller ubuntu

sudo dd efface tout le disque (mbr compris) et devrait s'arrêter, soit à la fin du disque (normal) soit avant si des secteurs ne peuvent être écrits. Comme nous n'avons pas le retour complet du sudo dd..., nous ne pouvons savoir s'il est allé jusqu'au bout.

Nota: un sudo dd.. peut durer plusieurs heures/jours selon la capacité du disque et sa vitesse. compter autour de 1h/10 Go

Re : [resolu] je n'arrive pas a reinstaller ubuntu

oui, ça a mis plus de 10 heures. Je n'ai pas noté le message mais il y avait un secteur en erreur.
Ce que je ne comprends pas, c'est que quand je réinstalle ubuntu avec la clef usb, à la fin j'ai le message que tout est ok, cliquer sur rebooter, et quand je relance je tombe toujours sur le même message :"default boot device missing or boot failed" .

Bonjour,
Je te prie de donner le nom complet du modèle de ton ordi Acer.
Peut-être que la solution de Gesbuklu pourrait fonctionner pour toi : https://forum.ubuntu-fr.org/viewtopic.p … #p21468818
Si ça ne marche pas, il y a la procédure plus raffinée de fnx : https://forum.ubuntu-fr.org/viewtopic.p … #p21604079

Re : [resolu] je n'arrive pas a reinstaller ubuntu

j'ai défini un mot de passe pour supervisor password, user password et HDD password mais j'ai toujours "secure an uefi file as trusted" en grisé, donc je n'arrive pas à faire la suite.

Re : [resolu] je n'arrive pas a reinstaller ubuntu

Puisque tu as viré Windows, tu peux changer le paramètre "Boot Mode" (il se trouve dans l'onglet "Boot" du Bios) qui se trouve actuellement sur UEFI pour le passer en autre chose en LEGACY. Tu pourras alors faire une installation de Ubuntu en mode non-EFI. Dans ce cas, plus besoin de la fonctionnalité "Select an efi file as trusted".

merci pour ta réponse.
Je viens de passer le bootmode en "legacy" (je n'ai pas d'autre choix).
Je relance l'install de linux et transmettrai le résultat

Re : [resolu] je n'arrive pas a reinstaller ubuntu

bon, ça ne fonctionne pas.
A la fin de l'installation de ubuntu, tout est ok, demande de rebooter.
Ensuite, à l'affichage :
1) blk_update_request
i/o error dev SR0 sector 11564
i/o error loop0 sector 10900, 902, etc
et
squashfs error : squashfs read_data failed to read block 0x552634

2) je force l'extinction et redémarrage du pc :
no bootable device - insert boot disk

Une idée ou une piste ?

Re : [resolu] je n'arrive pas a reinstaller ubuntu

Démarre ton ordi sur la LiveUSB et sélectionne "Try Ubuntu without installing" pour faire une session live. Fais un Boot-Info depuis la session live et donne l'URL de ce Boot-Info dans ta réponse.

Re : [resolu] je n'arrive pas a reinstaller ubuntu

le pc ne démarre plus avec la clef usb-live. J'ai vérifié l'ordre dans le boot, c'est dans l'ordre.
J'ai démarré avec le cd-live ubuntu 16.04, mais je pense que je ne vais pas arriver tout de suite à installer boot-info.
je suis en train de télécharger boot-repair-disk, mais avec ma connexion internet, j'en ai pour un moment.

en remettant le boot en uefi, la clef fonctionne, mais ça ne change rien. Par contre, la connexion ethernet ou wifi ne fonctionne plus ...

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi-amd64-signed of sda4, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Advice in case of suggested repair
BIOS-Boot detected. You may want to retry after deactivating the [Separate /boot/efi partition:] option.
Do you want to continue?


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/efi/.../grub*.efi file!


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

On y voit que Ubuntu 16.04 installé sur le disque dur est une installation faite en mode Legacy par ces deux indices :
1) pas de ligne de montage de la partition EFI dans le fichier fstab :

Par contre, cette installation n'est pas fonctionnelle actuellement parce qu'il n'y a pas de chargeur d'amorçage dans le MBR du disque dur. Je suis désolé mais là comme ça, je ne sais pas quoi te conseiller pour réparer le démarrage de ce Ubuntu installé.

Mais ce n'est pas possible d'effacer complètement le DD pour repartir à zéro ?

Si bien sûr que c'est possible de tout effacer et refaire tout à neuf (*). Là où je me suis dégonflé, c'est pour t'aider à réparer ton Ubuntu malade parce que tu étais vraiment mal engagé.
Après cela, si ça continue à ne pas booter comme avant, au lieu de toucher à tous les boutons et foutre la pagaille, je te prie de faire un Boot-Info et d'en donner l'URL dans ta réponse afin qu'on puisse analyser ce qui se passe et te conseiller précisément.

(*) je te suggère le choix "Effacer le disque dur et installer Ubuntu" à l'étape "Type d'installation"

Re : [resolu] je n'arrive pas a reinstaller ubuntu

merci de ta réponse.
oui, désolé, j'avais prévenu que je suis très faiblard sur linux.

1) voir le bootinfo à 09hh57 ne va pas ?
je pense avoir suivi ton lien du 23/01 à 18h56
- j'ai lancé un live ubuntu depuis un cd (externe)
- sur le lien, j'ai suivi le point "1.1.2 Cas où aucun ubuntu installé sur disque n'est opérationnel."
et j'ai mis le résultat de l'url bootinfo : http://paste.ubuntu.com/p/5CSVBV9zHw/

J'ai foiré kekechose ? Un conseil ?


2)  je te suggère le choix "Effacer le disque dur et installer Ubuntu" à l'étape "Type d'installation"
et oui, je l'avais fait, mais ça ne change rien au boot j'ai toujours ce bête choix.

Re : [resolu] je n'arrive pas a reinstaller ubuntu

On va essayer d'y aller par étape. Premièrement, il faudrait que tu parviennes à démarrer en mode Legacy sur ton LiveDVD mais d'après le Boot-Info que j'ai collé dans le post #16, ce n'est pas le cas puisqu'on peut y voir :
-----------------------------------------------
=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this live-session.
SecureBoot disabled. (maybe sec-boot, Please report this message to boot.repair@gmail.com)
-----------------------------------------------
ça dit que tu as démarré en mode EFI pour faire la session Live. Donc ça ne va pas.

Il faudrait que tu vérifies dans ton "Bios" si tu as la possibilité d'autoriser l'utilisation de la touche F12 comme expliqué dans ce doc : https://fr.answers.acer.com/app/answers … %a9marrage
L'intérêt de ça, c'est qu'en pressant la touche F12 au démarrage de l'ordi , tu peux faire apparaître le Boot Menu et que tu peux sélectionner à la volée le périphérique sur lequel tu souhaites démarrer.

merci de ta patience !
j'avais enlevé le mode legacy car je n'avais plus de connexion internet (mais finalement, c'était le câble).
J'ai remis legacy, et avec f12, j'arrive dans le boot manager
je vais refaire un boot info et mets le lien

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi-amd64-signed of sda4, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Blockers in case of suggested repair
La session actuelle est en mode Legacy. Veuillez redémarrer l'ordinateur, et utiliser ce logiciel dans une session EFI. Cela vous permettra d'utiliser cette fonctionnalité. Par exemple, utilisez un live-USB de Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), après avoir vérifié que votre BIOS est réglé pour démarrer l'USB en mode EFI.


=================== Advice in case of suggested repair
Le démarrage de votre ordinateur est en mode Legacy. Vous voudrez peut-être ré-essayer après l'avoir changé en mode EFI.
Alternativement, vous souhaiterez peut-être ré-essayer après avoir désactivé l'option [Partition /boot/efi séparée :].
Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !

Le démarrage de votre ordinateur est en mode Legacy. Vous voudrez peut-être ré-essayer après l'avoir changé en mode EFI.


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

Là tu as réussi puisqu'on peut voir :
-----------------------------------------------------
=================== UEFI/Legacy mode:
This live-session is not in EFI-mode.
-----------------------------------------------------

Ce que tu dois faire, c'est redémarrer en mode Legacy comme tu as réussi à le faire pour ce Boot-Info, et à faire l'install en sélectionnant "Effacer le disque et installer Ubuntu" (peut-être que le choix qui te sera proposé sera un peu différent, mais il faut prendre le choix qui efface le disque). Surtout ne coche pas la case "Chiffrer la nouvelle installation de Ubuntu pour la sécurité" et ne coche pas non plus la case "Utiliser LVM pour la nouvelle installation de Ubuntu"

Re : [resolu] je n'arrive pas a reinstaller ubuntu

ça fonctionne !! merci beaucoup !!!
il y a apparemment un petit problème (message "problème logiciel"" après être entré dans ubuntu), je vais voir si il ne faut pas faire de mises à jour (je suis toujours en 16.04), mais éventuellement dans un nouveau sujet.
Merci encore pour ton aide
