[Résolu]Problème d'installation d'Ubuntu 18.04LTS sur lenovo k410

nebus462 · Le 25/01/2020, à 13:50

Bonjour, cela fait 2 jours que je galère sur mon installation .J'aurais besoin d'un coup de pouce.

J'ai profité de la fin de w7 pour sauter le pas et enfin installer Ubuntu sur ma machine. C'est un lenovo ideacenter K410 intel core i7 3770, 8 Go de RAM, 1 SSD de 253 Go et 1 HDD de 1 To.
Je partage mon post en 2 parties.

1ere partie: Sur mon SSD j'ai 2 partitions: 1 de 250 Mo en efi et le reste pour / . ( oui je sais cela fait 10 fois trop mais je ne savais pas quoi en faire). Et sur Mon HDD J'ai aussi 2 partitions , 1 de 8 Go pour le SWAP et le reste pour /HOME . J'ai lu beaucoup de tuto sur le swap et comme perssonne n'est d'accord j'ai tranché pour le mettre sur mon HDD à la valeur de ma ram.
Qu'est ce que vous en pensez ? qu'est ce que je peut améliorer?

2eme partie: Et c'est là mon gros problème. Au redémarrage, j'ai "error 1962 no boot disk". Après quelques recherche je comprend que c'est un problème de UEFI. je suis un tuto ubuntu sur l'uefi. Je désactive le quick boot , je cherche intel SRT mais n'en trouve pas.Je vérifie que l'installation est bien en efi, que ma cession ordi est bien en efi. Ce qui est bizarre c'est quand je veux réglé le démarrage en efi il me propose que la clé live d'installation mais pas mon SSD. Je regarde donc avec gparted. Ma partition efi est en gpt, 250Mo, drapeau boot,esp. Mais pas de point de montage /boot/efi.

Je vous livre donc mon rapport boot info : http://paste.ubuntu.com/p/kNN687fH4W/ si vous pouviez y jeter un coup d'oeil.

J'ai trouvé aussi un forum lenovo qui explique que les lenovo ideacenters ne peuvent booter que windows. C'est en anglais, il propose une manip, mais je n'ai pas suivit toutes les subtilitées .Donc si vous voulez y jeter un coup d'oeil aussi en passant: https://forum.lenovo.com/t5/Ubuntu/K410 … -p/1562726 .

Partie 1: la partition swap n'est plus obligatoire. Avant on mettait 1,5 fois la RAM en swap. La partition EFI de 250 Mo c'est pas grave, au moins tu seras tranquille
Partie 2: en gros, la manip permet de faire croire au bios qu'on lance windows alors que ce n'est pas le cas (on lance grub qui lui même lance linux)

Le secure boot est activé? Si oui, tu peux le désactiver et tester

Bonjour
C est écrit donc
Faire le nécessaire pour faire apparaître le disque NVME dans le boot-info voir paragraphe 7.1 de https://doc.ubuntu-fr.org/cohabitation_ubuntu_windows
https://forum.ubuntu-fr.org/img/fluxtoo … bt_pre.png
Puis monter la partition

Rectification......
Fabriquer le point de montage

sudo mkdir -p  /boot/efi

et faire le montage

sudo mount /dev/sdb1 /boot/efi

### make a Microsoft/Boot folder in the EFI partition and copy Grub's file there
cd /boot/efi/EFI
mkdir Microsoft
mkdir Microsoft/Boot
cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

### add boot entry to EFI
efibootmgr -c -L "Windows Boot Manager" -l "\EFI\Microsoft\Boot\bootmgfw.efi"
### it is ESSENTIAL that you type it in *quotation marks*, or the backslashes will not work.

Si tu as cinq minutes à perdre, tu devrais regarder si en faisant seulement la commande

sudo efibootmgr -c -L "Windows Boot Manager" -l  "\EFI\ubuntu\grubx64.efi"

le boot a lieu.
Cela t'éviterais d'aller à la recherche des noms de partitions et de faire la copie

Je pense que tu commets une erreur en mettant le répertoire /home dans une partition. qui n'est pas dans le SSD... car il contient pas mal d'extensions logiciels
Tu devrais seulement mettre tes données personnelles dans la disque dur https://bluc.pagesperso-orange.fr/ps/

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb2, using the following options:        sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sdb1/efi/.../grub*.efi !


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

nebus462 · Le 25/01/2020, à 15:30

merci pour ta réponse.
Par contre j'ai besoin d'un peu plus d'informations pour faire la manip. Je n'arrive pas à atteindre le sdb1 ,ou se trouve la partition efi.
Pour l'instant je suis en live , ubuntu@ubuntu. et j'arrive pas à me placer sous /boot/efi. il ne trouve pas le dossier. est ce lié au fait que ma partition efi n'a pas de point de montage /boot/efi ?
Comme je l'expliquait plus haut , ce sont mes débuts sous ubuntu, il faut être conciliant. ^^
En tout cas merci.

geole · Le 25/01/2020, à 15:44

C'est pour cette raison que je proposais par essayer directement cette commande

sudo efibootmgr -c -L "Windows Boot Manager" -l  "\EFI\ubuntu\grubx64.efi"

Peut-être devras-tu auparavant frapper cette commande pour installer la commande efibootmgr

sudo apt install efibootmgr

Si tu n'a pas le point de montage , tu peux le fabriquer avec cette commande

sudo mkdir -p  /boot/efi

Bonjour,
A lire ce post ainsi que d' autres dans le même genre, je me suis posé la question du pourquoi, certains veulent galérer à choisir eux même les partitions, swap, etc....... alors que cela est fait automatiquement sans problèmes.
Du moins si tout le pc est réservé à ubuntu. Ceci n' est pas un troll mais une question, a savoir les motifs et raisons qui obligerait ce choix.
Merçi,

nebus462 · Le 26/01/2020, à 14:29

Merci encore pour vos réponses.
Geole j'ai essayé, réessayé, inversé mes DD ,réinstallé pour refaire une installation plus "propre" et refaire la manip, bref j'arrive toujours pas à démarrer sous ubuntu.
Je vous redonne un nouveau boot-info : http://paste.ubuntu.com/p/f7BggPQbBG/

Et pour te répondre Kaiki, c'est un mélange de plusieurs facteurs. D'avoir lu plein de tuto qui t'y incite un peu , de vouloir apprendre aussi en mettant les mains dans le cambouis, bref pourquoi faire simple quand on peut faire compliqué.

geole · Le 26/01/2020, à 17:51

Bonjour
Mais tu ne dis pas avec précision si c'est toujours le même message d'erreur!

A priori, tu as déjà fais quelques trucs par exemple dans la NVRAM

=================== efibootmgr -v
BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,0004,0006,000A,0001,0007,0008,0009

Boot0001* HL-DT-STDVD-RAM GH70N	BBS(CDROM,,0x0)AMBO
Boot0004* Windows Boot Manager	HD(1,GPT,d33a0cb6-b76f-4166-a530-fa34f1b44790,0x800,0xee6000)/File(EFIMicrosoftBootbootmgfw.efi)
Boot0006* Windows Boot Manager	HD(1,GPT,d33a0cb6-b76f-4166-a530-fa34f1b44790,0x800,0xee6000)/File(EFIubuntugrubx64.efi)

Par exemple dans la partition de boot On y voit bien le répertoire windows et son fichier de boot

sda1: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Boot files:        /EFI/ubuntu/grub.cfg /EFI/BOOT/fbx64.efi 
                       /EFI/ubuntu/fwupx64.efi /EFI/ubuntu/grubx64.efi 
                       /EFI/ubuntu/mmx64.efi /EFI/ubuntu/shimx64.efi 
                       /EFI/Microsoft/Boot/bootmgfw.efi

Le boot-info est incapable de dire si tu l'as bien écrasé par le fichier de boot de ubuntu.
Si tel est le cas, je te propose de refaire la manipulation en "embarquant" la totalité du répertoire. Probablement ces commandes

sudo mkdir -p  /boot/efi

et faire le montage

sudo mount /dev/sdb1 /boot/efi

et faire la copie du répertoire

sudo cp   -v   /boot/efi/EFI/ubuntu/*   /boot/efi/EFI/Microsoft/Boot

et refaire la copie du fichier

sudo cp   -v   /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

Mais peut-être que ton problème de boot est déjà réglé et que tu es dans le problème de l'écran de démarrage de ubuntu qui ne s'affiche pas car tu n'as pas de dual boot. Pour le faire apparaître, regarde la documentation du mode recovery https://doc.ubuntu-fr.org/recovery_mode
( La lumière du paragraphe 2 )

Alors oui c'est toujours le même message d'erreur 1962.
J'essaye la manip et je te tiens au courant.
Bon toujours le même résultat: "Error 1962 : no operating system found. Press any key to repeat boot sequence"
J'ai regardé le tuto sur le mode recovery. J'ai beau appuyer sur echap ou entrée, rien ne se passe, j'arrive au message d'erreur.
J'ai refait un boot-info:

Faut il réinstaller w7 pour régler le problème?

Tu devrais aller dans le bios et regarder ses priorités de boot.
Il se pourrait qu'il boote prioritairement en mode LEGACY.
- Dans le premier boot info, c'était vide.
- Dans le dernier ce n'est pas mieux

============================= Boot Info Summary: ===============================
 => Grub2 (v1.99-2.00) is installed in the MBR of /dev/sda and looks at sector 
    2048 of the same hard drive for core.img, but core.img can not be found at 
    this location.

S'il boote prioritairement en EFI, il est possible qu'il déteste le module SHIMX64 ubuntu
Première chose à faire, explorer tout le bios pour voir s'il ne te propose pas une liste de fichiers de boot dans laquelle il faut que tu choisisses.
Les ordinateurs ACER le font mais ils ne sont plus les seuls
Seconde chose, Au vu de ce contenu

================== efibootmgr -v
BootCurrent: 0000

Je te propose de booter avec un support d'installation et voir si tu peux lui indiquer une autre entrée que la valeur 0 avec cette commande

sudo efibootmgr   -o  4,6

nebus462 · Le 26/01/2020, à 22:52

Bon j'ai bien épluché le BIOS, a aucun moment UEFI apparait, je ne peut sélectionner aucun fichier à booter. c'est un peu le désert comme BIOS. Au cas où j'ai regarder si il y avait une mise à jour du BIOS mais rien pour ce modèle ( de toute façon j'ai l'impression que tu ne peut qu'en passant par Windows).
J'ai bien fait la modif efibootmgr . J'ai gardé que les entrées 0004 et 0006. Mais toujours pas de changements, encore la même erreur 1962.
Je te repose la question, est ce que si je réinstalle w7 et après ubuntu cela pourrait résoudre le problème, ou est ce que même dans ce cas ubuntu ne sera pas pris en compte?
Autrement existe t'il un moyen de corriger le problème avec core.img?
Et encore merci de prendre du temps pour mon problème.

Refaire la même chose donne très souvent le même résultat, tant qu'on n'a pas trouvé le "piège" à éviter.

Je suis incapable de savoir si ton ordinateur boote en mode LEGACY ou en mode EFI et encore moins capable de savoir si tu installes en mode LEGACY ou EFI.

Le core.image qui vient d'apparaître n'est présent qu'en legacy

Pour décider comment tu bootes, c'est dans le bios qu'il faut chercher.
Pour vérifier comment le boot a eu lieu, c'est le paragraphe 2.3 de cette documentation https://doc.ubuntu-fr.org/uefi
Le paragraphe 4 explique comment passer d'un mode à un autre.

Comme on a fait pas mal de choses en EFI, il faudrait privilégier la piste LEGACY appelée aussi CSM

nebus462 · Le 27/01/2020, à 10:21

bonjour,
Pour répondre à ta question, j'avais déjà suivit ce tuto. L'installation est bien en UEFI. Et la cession était aussi en UEFI.C'est le démarrage en UEFI qui me posait problème.j'ai relu le tuto sur UEFI, et j'ai essayé de reconfigurer le démarrage UEFI (f12) comme je l'ai fait déjà une bonne dizaine de fois
Et là oh miracle! L'ordi me propose de démarrer le disque SSD en UEFI. Donc j'ai pu démarrer ubuntu pour la première fois!

J'ai donc commencé à l'utiliser. Mais je me dis que je vais le redémarrer pour voir si le problème est vraiment solutionné. Premier démarrage, il me remet erreur 1962. Deuxième démarrage, je réessaye f12 pour gérer le démarrage UEFI, et là déception il ne me propose plus le mode UEFI pour mon SSD. J'ai rien modifié entre ces différents essais. Je ne comprend pas. Mais on est proche de la solution!
Auriez vous une idée?

Bonjour
Comme tu as réussis une fois.. Il y a de l'espoir.
Il faudrait que tu prennes des photos de la majorité de ce que le bios propose comme options. En les voyant, peut-être qu'il sera possible de voir une option permettant d'améliorer le démarrage.
NOTA. Les photos sont a poster dans un site de partage de photos. Liste non exhaustive.

Regarde en premier comment l'accès au ssd est fait RAID? IDE? AHCI? IRST? autre?

Donc voilà mon bios. Et tout en miniature. ^^
Et pour répondre à ta question le SSD est en mode AHCI.

_{Modération : merci d'utiliser des images de petite taille (300x300) ou des miniatures pointant sur ces images (Des hébergeurs comme Toile Libre ou TDCT'Pix le permettent).}

Utilise un autre site qui ne limite pas si drastiquement.
et développe la 5eme photo sur la partie Primary boot sequence.

Développe aussi la partie sécurity. Certains bios ont la particularité de demander de mettre un mon de passe a l'administrateur du bios. Dans ce cas, un seul caractère est bien suffisant.

Effectivement ton bios est assez simple J'ai vu qu'il date de 2012...

Comme ça tu as la totale. Comme tu peut le voir , il n'y a plus le choix sur le SSD entre uefi et legacy. Alors que ce matin il s'est affiché et c'était la première fois. Par contre la clé USB live s'affiche à chaque fois comme il faut. J'ai du mal à comprendre vu que je n'ai rien touché à ce moment là.
J'ai mis un caractère pour le mot de passe administrateur comme tu le conseil, mais pas de changement.

Après un petit tour chez lenovo, la mise à jour du bios ne se fait que depuis Windows...^^

malbo · Le 27/01/2020, à 20:23

Bonsoir,
La photo ici montre que tu as la possibilité de démarrer sur la clé USB en mode Legacy (choix "Legacy: USB DISK 2.0 PMAP"). Je te suggère de démarrer comme ça et de refaire entièrement l'installation de Ubuntu dans ce mode Legacy. Motif : ton Bios tout vérolé ne te permet pas de démarrer systématiquement en mode EFI sur le disque dur donc il vaut mieux lâcher le mode EFI...

EDIT le 28 janv 2020 : pour garder une trace de l'état précédent, je colle ci-dessous le Boot-info dont tu as donné le lien ( http://paste.ubuntu.com/p/TyFwDbfPY4/ ) dans le post #10 :

Boot Info Script 8f991e4 + Boot-Repair extra info      [Boot-Info 25oct2017]


============================= Boot Info Summary: ===============================

 => Grub2 (v1.99-2.00) is installed in the MBR of /dev/sda and looks at sector 
    2048 of the same hard drive for core.img, but core.img can not be found at 
    this location.
 => No boot loader is installed in the MBR of /dev/sdb.
 => Syslinux MBR (5.00 and higher) is installed in the MBR of /dev/sdc.

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


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

Si votre ordinateur redÃ©marre directement sur Windows, essayez de changer l'ordre de dÃ©marrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de dÃ©marrage, changez l'entrÃ©e de dÃ©marrage par dÃ©faut de l'amorceur Windows.
Par exemple, vous pouvez dÃ©marrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateurÂ :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

Ok je relance l'installation. Et je reviens vers vous.
Bon j'ai l'immense joie de annoncer que tout fonctionne à la perfection ! Plusieurs redémarrages et arrêts pour vérifier, mais tout roule....
Un grand merci à vous tous!!!

Bonsoir
"Refaire la même chose donne très souvent le même résultat, tant qu'on n'a pas trouvé le "piège" à éviter."
Le piège vient d'être déactivé. Il serait bon que tu refasses un boot-info.
Malbo manipule beaucoup mieux que moi cette mise à jour

C'est une excellente nouvelle.
A retenir pour ceux qui tomberaient sur cette discussion : il faut réaliser l’installation de Ubuntu en mode Legacy et non pas en mode UEFI. Pour y parvenir, connecter la LiveUSB Ubuntu, presser la touche F12 au démarrage de l'ordi pour faire apparaître le Boot menu (photo) dans lequel on doit trouver la clé USB qui devrait proposer le choix Legacy et UEFI. Il faudra sélectionner "Legacy" et valider ce choix. Ainsi le démarrage sur la LiveUSB sera en mode Legacy et l'installation de Ubuntu sera bien dans ce mode Legacy.

@geole : je ne peux pas ajouter le modèle IdeaCentre K410 dans la Liste des portables « Lenovo » parce qu'il s'agit d'une tour (pas d'un portable)

EDIT : pour clore la discussion, je te prie de procéder comme suit :
1) te connecter sur le forum
2) cliquer sur "Modifier" en bas à droite de ton PREMIER post
3) modifier le titre de la discussion pour qu'il devienne :

Je vous remet un boot info après installation comme demander par Geole.
http://paste.ubuntu.com/p/TpbXnhYfzX/
Il y a encore une chose que je ne comprend pas, c'est que j'avais déjà essayé l'installation en legacy mais qu'elle n'avait pas fonctionné à ce moment là. Pourquoi cette fois à été différente?
Merci encore!
