Installer le Grub en dualboot avec Asus UEFI et 18.04

Bonjour à tous,

Je souhaite revenir vers Ubuntu, j'ai opté pour un nouveau SSD en complément de celui de Window et d'un disque de stockage.
L'installation de 18.04 par clé USB se passe sans problème sauf pour le grub.
D'après le rapport, SECUREBOOT semble désactivé et l'EFI compatible: http://paste.ubuntu.com/p/BdVK9FKBBW/ .
J'ai certainement raté une étape, mais laquelle ?
Quels sont les paramètres à modifier dans l'UEFI ASUS, SECUREBOOT sur Other OS et CSM sur UEFI ?
Une installation manuelle du Grub m'a l'air assez compliquée, j'espère que ce ne sera pas nécessaire.

Dans l'attente de vos conseils,

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

Bonjour,
Au démarrage de la machine, si le menu de choix Ubuntu/Windows (grub) ne s'affiche pas et démarre Windows, alors sous Windows, ouvrez la ligne de commande et tapez ceci, puis redémarrez :

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Desktop : Ubuntu Mate 18.04 - Intel i5 - 8 Go - Dual boot Windows 7 pour jouer
Laptop asus : Ubuntu Mate 18.04 - Intel i5 - 4 Go
Vieux laptop de 2005 : Bodhi Linux - Pentium M - 436 Mo

Merci LukePerp,
Mais je me suis enfoncé un peu plus, j'ai voulu reformater le SSD et maintenant, l'installateur ne propose plus le dualboot bien que Window soit fonctionnel.
Je fais un essaie dès que je peux réinstaller 18.04

Ok, j"ai pu refaire une installation, le dualboot n'était pas proposé et le grub ne c'est pas installé.
J'ai essayé la commande proposé mais bcdedit / semble poser problème: La commande de définition spécifiée n’est pas valide.
Je dois renoncer pour ce soir, je ferais une autre tentative demain.

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

Salut,

D'après le boot-info, WIndows est installé en mode CSM/BIOS donc il est nécessaire d'installer Ubuntu dans ce même mode, cela explique tes deux échecs d'installations.

=================== 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
Please do not forget to make your BIOS boot on sdc (ATA PNY CS900 240GB) disk!

The boot files of [Ubuntu 18.04.2 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)


=================== 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

Non, pas de mode opératoire particulier, les configurations des firmwares/Bios d'une machine à une autre sont tellement différents y compris pour des machines de même marque que j'ai renoncé à conseiller quoi que ce soit pour choisir entre les deux modes de démarrage.
En gros tu cherches dans les différents onglets de gestion du firmware quelque chose permettant de choisir un démarrage du système en mode CSM/BIOS avec une clef.
Ce n'est pas toujours clair et parfois les termes BIOS ou CSM n'apparaissent même pas.

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

À noter que le disque /dev/sda héberge une table de partitions GPT, mais la partition système de Windows est sur le disque /dev/sdb qui a une table de partitions msdos et je ne vois aucune mention d'un démarrage en mode uefi.
Le disque /dev/sdc a une table de partitions msdos.
C'est juste une précision au cas où certains pourraient penser que l'installation de WIndows est en mode UEFI à cause de la présence d'une table GPT dans le disque /dev/sda.

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

Salut,

Il faudrait déjà refaire un rapport boot-info en bootant sur le liveCD en mode Legacy :

BIOS is EFI-compatible, and is setup in EFI-mode for this live-session.

Ce sera l'occasion de voir ce qu'il propose comme réparation.  Et pour info, cette commande ne peut bien entendu pas fonctionner (et je persiste à dire qu'on doit l'éviter autant que possible) :

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

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

Parce que bootmgr est un lanceur Windows, et qu'il est préférable qu'il pointe vers le fichier de démarrage de Windows, à savoir bootmgfw.efi. Le bidouillage consistant à le faire pointer vers un shimx64.efi ou un grubx64.efi ne peut que créer des problèmes pour plusieurs raisons :

- Si on fait une faute de frappe, Ws ne bootera plus. Et il faudra un support externe Ws pour réparer.
- La commande ne sert souvent à rien et les PC bridés continuent de booter sur Windows malgré tout. Exemple ici
- Si elle passe, on aura un plantage avec grubx64.efi si on a oublié de désactiver le secure-boot.
- En cas de problème sur Ubuntu, et que GRUB dysfonctionne, on ne pourra plus lancer Windows directement via le BIOS-Uefi. Et idem que le premier point.
- Chaque mise à niveau et certaines mises à jour de Ws annuleront la commande.

Bref, on ne passe par cette commande que si on ça épuisé toutes les solutions "normales".

Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot

C'est acceptable, même si l'écriture de grub2 dans le mbr de chaque disque ne se justifie pas et peut poser souci à ton Ws s'il se retrouve un jour seul dans le PC. Vois si les options avancées de boot-repair permettent de limiter l'action à /dev/sdc. Si oui, tu pourras le faire, et une fois GRUB ajouté à sdc, il suffira de placer ce disque en tête dans le BIOS pour que ça boote dessus.

Si tu ne trouves pas l'option, il faudra passer par un chroot ou par supergru2disk pour faire la manipulation.

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

Je ne suis pas certain que boot-repair puisse correctement fonctionner dans la mesure où grub n'est pas installé dans /boot/grub/i386-pc.
Je ne connais pas bien boot-repair, je me demande simplement si ce logiciel refait totalement l'installation de Grub ou si il se contente uniquement de tenter une initialisation du mbr et du  menu grub.
Personnellement je referais une installaton en mode CSM/BIOS dans la mesure où c'est une nouvelle installation et qu'il ne semble pas nécessaire de la préserver.

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

Il me semble que boot-repair fait une installation complète de GRUB, mais si tu choisis l'option de Maxire, débranche le disque Windows et le disque gpt, ce qui évitera que GRUB s'installe au mauvais endroit.

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

Tu peux également tenter un boot-repair après avoir débranché les deux disques WIndows ce qui évitera de polluer leurs mbrs.
Il faudra ensuite juste passer la commande update-grub pour intégrer Windows dans le menu Grub et également penser à mettre le disque Ubuntu prioritaire au démarrage.
Si boot-repair se plante au moins Windows ne sera pas touché.

Bonjour à tous,
Voilà ou j'en suis, 18.04 parfaitement installé sur son disque mais Ws10 et le disque de stockage qui ne sont pas reconnus.
http://paste.ubuntu.com/p/DPzGtkDG42/ .
Dans ce cas, il ne manque que le dual-boot.
Je vais faire des recherches sur le sujet, c'est peut être plus facile à traiter que le cas précédent mais si vous avez des liens je suis preneur.

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

Salut,

Je ne comprends pas très bien, tu as précédemment réussi à générer un boot-info en mode Legacy et tu viens d'installer Ubuntu en mode UEFI alors que tu aurais dû l'installer en mode Legacy, donc tu as trouvé comment démarrer une installation en mode Legacy.
Le plus simple est d'installer Ubuntu en mode Legacy si tu veux pouvoir accéder facilement à WIndows.

Note :
Après relecture du premier message, je m'apeçois que nous n'avons aucune idée du mode d'installation utilisé lors de l'échec  de l'installation de Grub.
J'ai déduit trop vite que c'était une installation en mode UEFI alors que tu ne donnais aucune information sur l'erreur d'installation elle-même.

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

Salut,

Il faut effectivement formater /dev/sdc complètement pour virer cette partition efi qui s'est ajoutée sur un disque DOS (grande nouveauté de la dernière version Ubuntu), et refaire une installation en legacy.

Car là, tu n'auras jamais (j'exagère, car il y a une astuce, mais c'est à éviter) de dual-boot avec Windows.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to unsign) and 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 18.04.2 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

Salut,

Tu en es toujours au même point, Windows installé en mode CSM/Legacy/Bios (appelle ce mode comme tu veux) et Ubuntu installé en mode EFI.
Mon conseil est toujours le même, relance l'installation de Ubuntu mais en mode CSM/Legacy/Bios après sauvegarde des données pour une éventuelle restauration de celles-ci dans ta nouvelle version de Ubuntu.

ikewdu a écrit :

Car là, tu n'auras jamais (j'exagère, car il y a une astuce, mais c'est à éviter) de dual-boot avec Windows.

Je dirais même deux astuces, une Windows, une Linux,  mais à éviter tout de même.

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

Salut,

Ton problème est toujours le même : tu as un WS sur sdb qui est installé en mode legacy (BIOS) sur un disque dos.

Disk /dev/sdb: 223.6 GiB, 240057409536 bytes, 468862128 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x42cf4884

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sdb1  *         2048   1026047   1024000   500M  7 HPFS/NTFS/exFAT
/dev/sdb2         1026048 467766120 466740073 222.6G  7 HPFS/NTFS/exFAT
/dev/sdb3       467767296 468856831   1089536   532M 27 Hidden NTFS WinRE

Et tu as un Linux installé en uefi.... Également sur un disque dos :

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.

Device     Boot   Start       End   Sectors   Size Id Type
/dev/sdc1  *       2048   1050623   1048576   512M ef EFI (FAT-12/16/32)
/dev/sdc2       1052670 468860927 467808258 223.1G  5 Extended
/dev/sdc5       1052672 468860927 467808256 223.1G 83 Linux

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