Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Bonjour à tous,

J'espérai une autre solution, je n'ai pas réussi à faire l'installation de Linux en mode Legacy malgré les nombreuses tentatives et modifications de paramètres, donc à moins d'avoir un spécialiste à domicile, je ne pense pas y parvenir. Au pire, je peux choisir le disque de démarrage à partir du BIOS lorsqu'ils sont reconnus (aléatoire). A moins que vous aillez une autre solution, même un bricolage pour que les disques soient reconnus.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Le firmware pose donc problème, donne le retour de :

sudo dmidecode -t bios -t system -t baseboard

Cela nous permettra de connaître les caratéristiques du firmware et de la carte mère.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

ikewdu a écrit :

Le plus simple est donc de réinstaller ton Linux lui aussi en mode Legacy pour que les deux soient compatibles.

Bonjour

Le retour de la commande  dit  ""USB legacy is supported"

Pour booter en LEGACY,   il faut que tu appuies sur une touche   au démarrage du boot . Le menu de boot s'affiche alors,
Tu y verras la liste des fichiers de boot du support USB.    Tu ne choisis pas celui qui se termine par .EFI mais l'autre


    Pour la touche, c'est souvent F12 ,F11, F9 ,  F2    et rarement ECHAP
     Il faut aussi que tu regardes dans le bios si tu n'as pas déactivé la possibilité de booter en LEGACY (CSM)   pour n'avoir que UEFI

Lorsque tu as booté, tu vérifies que c'est bien en LEGACY  https://doc.ubuntu-fr.org/uefi#verifier … pport_live

User choice: Est-ce que sdc (ATA PNY CS900 240GB) est un disque amovible ? no




=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdc5 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdc (ATA PNY CS900 240GB) !

Les fichiers de démarrage de [Ubuntu 18.04.2 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Tu as bien booté en LEGACY.

=================== UEFI/Legacy mode:
This live-session is not in EFI-mode.

Ubuntu est bien installé  dans la partition SDC5 et les deux O.S. sont bien détectés.

=================== os-prober:
/dev/sdb1:Windows 10:Windows:chain
/dev/sdc5:Ubuntu 18.04.2 LTS (18.04):Ubuntu:linux

Je ne sais pas à quoi sert la partition SDC1 qui est vide.

Je ne comprends pas pourquoi les MBR n'ont pas été mis à jour.

Pour réparer, utilise la réparation automatique de boot-repair. https://doc.ubuntu-fr.org/boot-repair

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

SDC1 est proposé automatiquement, il contient un dossier de 3.7Go il me semble, je l'ai donc laissé sans savoir à quoi il sert.

Je n'arrive pas à installer Boot-repair, vois-tu un problème ?

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Effectivement l'installation en mode legacy de Ubuntu rate dans ce cas, grub n'est pas installé.
Pourquoi ?
Mystère.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdc5 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot

Je ne suis pas vraiment d'accord avec cette proposition de réparation car si l'installation de Grub rate je ne vois pas de raison qu'elle réussisse avec boot-repair et dans ce nouveau cas d'échec il existe de fortes chances pour que Windows soit également indémarrable.

Je pense qu'il serait préférable de laisser l'installation de Ubuntu en mode UEFI et de jongler avec le menu de démarrage du firmware.
Je possède également un ASUS avec firmware American Megatrends et je peux démarrer facilement les différents OS aussi bien en mode UEFI que Legacy.
Touche Echappement dans le cas de ma machine pour accéder au  menu de démarrage, f2 pour le paramétrage du firmware et f9 pour démarrer un shell UEFI (à condition qu'il soit installé).

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Bonjour
Dans ce cas, il est plus simple de  booter  avec le support d'installation, de faire la procédure CHROOT et de demander d'installer  la structure de boot uniquement dans le MBR du SDC et de modifier le bios pour booter sur le SDC
Qu'en pensez-vous?

Ou alors de demander de réinstaller windows en mode EFI ce qui va obliger à fabriquer une table de partition GPT sur le disque en question

Pour boot-repair, c'est  probablement un problème de réseau qui perd des bits, refais comme cela

sudo apt install --reinstall   boot-repair 
sudo apt install --reinstall   boot-info

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Je pense à une chose, lors de l'installation de Grub il est demandé sur quel disque installer Grub, ne serait-ce pas /dev/sda qui est choisi par défaut ou bien le sélectionnes-tu ?
Dans ce cas comme ce disque possède une table de partitions GPT il est normal que l'installation de Grub rate faute de pouvoir créer une partiton bios_grub.
Lors de l'installation en mode Legacy il faut sélectionner le disque /dev/sdc pour y installer Grub.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Plusieurs questions:
Avant l'instal, je préfère formater le disque, quelle est la bonne méthode ou les bonnes options ?
L'installateur propose deux partitions, l'une avec Ubuntu sdc5, l'autre avec un dossier dont j'ignore l'utilité, à quoi sert-il ?
Concernant Grub, c'est bien sur sdc, sdc1 ou sdc5 que j'essaye de l'installer.
Réinstaller W10 me parait difficile.
Comment passer en chroot ?

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Proposition chroot   voir document   https://doc.ubuntu-fr.org/chroot  Ce qui devrait donner dans ce contexte

setxkbmap fr      
sudo -i    

       

mount   /dev/sdc5 /mnt

Le montage des répertoires se fera avec ces commandes (copier/coller).

   mount -t proc  /proc              /mnt/proc
   mount -t sysfs /sys               /mnt/sys
   mount --bind   /dev               /mnt/dev
   mount --bind   /run               /mnt/run
   mount --bind   /sys               /mnt/sys
   mount --bind   /etc/resolv.conf   /mnt/etc/resolv.conf
    

Le changement d'environnement se fera avec cette commande

  chroot /mnt

Quelques contrôles seront à faire par exemple

mount -t devpts devpts /dev/pts 
df -h && df -i
ping -c4 8.8.8.8  && ping -c4 google.fr
ls   -ls /home
grub-install    /dev/sdc

Merci de rectifier si je me suis trompé pour la commande d'installation légacy que je connais peu.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

il reste à quiter     

exit
shutdown

Puis à modifier le bios pour dire que les disques de boot  sont  dans l'ordre suivant SDC SDB  SDA
et booter pour voir ce que cela va donner

C'était bien une installation en mode  Bios, sans menu cela ne risque pas de marcher, il aurait fallu le générer via update-grub.
Il suffira de repasser en chroot et cette fois-ci de passer la commande :

sudo update-grub

puis reboot.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Bonsoir.

J'interviens dans ce fil uniquement au sujet de Boot-Repair utiliser en mode Bios_Legacy. Pas en UEFI.
J'ai testé à l'époque pour YannUbuntu, les scripts de Boot-Repair au fur et à mesure de sa conception, jusqu’à l’apparition des machines en mode UEFI. N'ayant pas de machine UEFI, j'ai donc du lâcher prise...

Pour réinstaller Grub-pc Boot-Repair propose deux modes de réparation. La "Réparation recommandée", ou les "Options avancées".

Boot-Repair est utilisable en session installée. En cas de multi boot Linux, il ne va réinstaller Grub que dans l'Os Linux qui permet de le lancer, celui où on l'a installé.

Boot-Repair utilisé en session live, permet de réinstaller Grub dans tous les Os Linux de la config.

Rappel au sujet de Grub-pc; L'installation se fait en deux parties indissociables.
La première partie, en général, dans le secteur de boot du disque d'installation, ou dans le secteur de boot de la partition système, dans le cas où l'utilisateur désire chaîner d'un Grub à l'autre.
La deuxième partie dans la partition système dans /boot/grub.

Particularité des config multi boot multi disques (internes ou internes/externes).
Après lancement de Boot-Repair, en présence de plusieurs disques avec des systèmes Linux installés, la question suivante est posée;

Exemple dans le sujet qui nous occupe;

Est-ce que sdc (ATA PNY CS900 240GB) est un disque amovible ? no

Est-ce que le disque ...... est un disque amovible.
Si on répond;  Non ce qui est logique en présence de disques internes.
Boot-Repair propose de réinstaller la première partie de Grub dans les secteur de boot de tous les disques de la config, à l’exception des disques externes sans Os installés.

Si on répond; Oui , bien que ce soit faux, Boot-Repair va réinstaller la première partie de grub dans le secteur de boot du disque qui a reçu l'installation.

Pour les contributeurs curieux, possédant une config multi boot multi disques, lancez Boot-Repair en session live Bios_Legacy, répondez oui et non à la question, et regardez ce que propose la réparation recommandée. Vous constaterez les réponses ci-dessus.
Remarque; On retrouve dans les "Options avancées" les propositions par défaut identique à ce que propose la "Réparation recommandée" .

Pourquoi çà a marché comme çà?.
YannUbuntu estimait qu'en cas de multi disques, si l'utilisateur ne savait par faire le changement de périphérique au démarrage, pour démarrer sur le bon, la machine démarrerait quel-que soit le disque utiliser au démarrage, après réparation.

J'avais bien à l'époque soulevé le cas de config multi disque, multi boot, avec un disque où seul un Windows serait installé, et dont on voulait préservé le mbr compatible Windows.
Yann à pensé que l'on pourrait dépanné personnellement les utilisateurs dans ce cas. Utilisation des CD  d'install Windows ou console de récupération...

Puis avec l'insistance de pas mal d'utilisateurs de Boot-Repair, Yann à trouvé comment faire un script pour restaurer un "mbr generic" compatible Windows, çà semblait régler le souci, puisque l'on pouvait réécrire un mbr compatible Windows, écrasé par grub première partie.  Boot-Repair est donc resté en l'état.

@+.   Babdu89  .


J'ai découvert Ubuntu avec la 07.10.... Et alors?!...  Depuis je regarde de temps en temps si Windows marche toujours....

Bonjour,

Après

sudo update-grub

User choice: Est-ce que sdc (ATA PNY CS900 240GB) est un disque amovible ? no




=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdc5 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdc (ATA PNY CS900 240GB) !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 18.04.3 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Et que se passe-t-il maintenant ?
D'après ce que je lis dans le boot-info tu devrais pouvoir démarrer Ubuntu autant que Windows via le menu de Grub.

Labuche a écrit :

je ne peu plus booter depuis le bios

C'était l'objectif de la manipulation, maintenant tu n'as plus que le choix des disques de démarrage puisque plus aucun OS ne démarre en mode UEFI.
Toutes tes installations sont dans le même mode donc sont visibles par Grub, ici en mode Bios/Legacy.

@Babdu89, merci pour les informations, je n'utilise jamais boot-repair, il faut dire que je n'utilise plus Grub mais Syslinux en mode Bios et Refind en mode UEFI.
Grub est devenu trop sohistiqué donc fragile et je trouve même que ses dernières versions régressent.
Il est maintenant quasi impossible de pointer vers un  autre OS à partir d'un minimal grub shell en cas de déficience de l'OS maître, je pouvais le faire facilement voici quelques versions de Grub.
Comme toutes mes machines comportent un OS principal et un OS de réparation j'ai fait sauter Grub son mode commandes minimales étant devenu inopérant.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

Il reste tout de même un problème :
/dev/sdc1, partition en ext4 prenant plus de la moitié de la taille de /dev/sdc si je lis bien et qui n'est pas utilisée.

Je ne comprends pas.

Re : Installer le Grub en dualboot avec Asus UEFI et 18.04

L'installateur propose deux partitions, l'une avec Ubuntu sdc5, l'autre avec un dossier dont j'ignore l'utilité, à quoi sert-il ?

Oui, je ne sais pas pourquoi.

Bonjour.

l'autre avec un dossier dont j'ignore l'utilité, à quoi sert-il ?

Le nom du dossier; lost+found ?.

C'est un dossier qui est créé lorsque l'on formate une partition vide au format Ext4 .

J'ai découvert Ubuntu avec la 07.10.... Et alors?!...  Depuis je regarde de temps en temps si Windows marche toujours....
