[Résolu] Dual boot Ubuntu 15.10 et Mac : problème de boot

Vlau14 · Le 19/11/2015, à 15:43

Bonjour,

J'ai (voulu) installé(r) Ubuntu 15.10 en dual boot sur mon iMac. J'ai donc créé une partition spécifique en FAT32, indiqué un point de montage et tout et tout...
Ubuntu 15.10 fonctionne bien, RAS.
Au lancement, le système me propose de booter sur Ubuntu ou sur Mac OS, mais, lorsque je veux lancer Mac OS, j'ai un "kernel Panic" et le système ne se lance pas.
Sur mon disque, le dossier Mac (où se trouve le système OS) est resté intact, donc pas de problème de ce coté là.
J'ai aussi en /dev/sda1 une partition EFI,
je pense donc qu'il doit s'agir d'un problème de boot (le système ne sait pas où trouver l'OS X).
Est-ce que quelqu'un peut m'aider, sachant que mon expertise en systèmes informatique est moyenne ?

D'avance, merci.
Lars.

Bonsoir
Je ne sais que te dire, Mais on ne sera certainement pas nombreux a regarder
Je te propose de faire un boot-info .
https://doc.ubuntu-fr.org/tutoriel/boot-info
Je pense qu'avoir deux partitions FAT32 ne devrait pas être gênant.

Bonjour et merci de ton aide.
Voici le rapport du boot-info, le système OS est dans la partition sda2, mais on dirait qu'il n'y a pas de boot...

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda3, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file rename-ms-efi


=================== Final advice in case of suggested repair


Vous souhaiterez peut-être aussi installer Refind. ([url]https://help.ubuntu.com/community/ubuntupreciseon2011imac[/url])

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 15.10] 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]. ([url]http://doc.ubuntu-fr.org/tutoriel/partition_boot[/url])


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

Modération : merci à l'avenir d'utiliser les balises code (explications ici).

Ce qui veut dire que le grub a du te proposer deux options pour lancer le MAC
version 32 bits ou version 64 bits.
Tu ne dis pas si tu les as essayées toutes les deux.

Effectivement, j'ai essayé les deux.

• en 32 bits, j'ai le message :
- "erreur : Mach-0 dosen't contain suitable 32-bit architecture
- "erreur : le noyau doit d'abord être rechargé"
• en 64 bits, j'ai un message d'erreur (1ere ligne) :

panic(cpu0 caller 0xfffff80002a3d67): "pmap_map_bd: Invalid kernel adress\n"@/SourceCache/xnu/xnu-2050.9.2/osfmk/i386/pmp_x86_common.c1524

et après de nombreuses lignes de code cette conclusion :
- Mac OS version : Not yet set

• J'ai aussi essayé de booter sur "hda partition 2" avec un iso "Plop Boot Manager", mais ça n'arrive à rien non plus (écran fixe, barre clignotante).

Joli casse-tête !

Bougron · Le 21/11/2015, à 16:22

Je te donne un piste de dépannage possible
J'ai vu dans une discussion que lorsque la machine met en route qu'il serait possible de prendre la main et de demander le boot directement sur apple

http://apple.stackexchange.com/questions/170419/attemping-dual-boot-with-refind-mac-os-x-ubuntu-14-04-unexpected-behavior a écrit :

The good news is that I can boot into OS X using the option key at the startup sound. As a test, after restarting from OS X, I am still brought back to GNU GRUB. I booted into Ubuntu again as a test and that started up fine.

Vlau14 · Le 21/11/2015, à 17:54

Alors là, bravo !
Effectivement, appuyer sur la touche "option" (pas pomme) permet d'arriver sur rEFIt et de choisir un démarrage en Mac.
Encore merci pour le coup de main, je suis absolument ravi d'avoir sur la même machine OS X (pour l'emploi de certains logiciels pro) et Ubuntu 15.10 (pour le reste du temps).
Je crois que l'on peut mettre en "résolu".

Bougron · Le 21/11/2015, à 19:01

Il faut croire que tous les mac ont la même logique. Cela fait plaisir.

C'est à toi de revenir dans ton premier message, de prendre l'action de le modifier, de te positionner sur le titre et d'ajouter au tout début
[Résolu]

Au fait, avec cette technique, aurais-tu pu lancer ubuntu ???

Ce qui est super, c'est qu'il suffit de relancer le mac en appuyant sur la touche option une seule fois. Ensuite, à chaque démarrage, c'est rEFIt qui prend la main (le multiboot de Mac) et on peut choisir sa session en Mac OS ou Ubuntu. Mais il faut avoir pensé à installer rEFIt sur le mac avant d'installer Ubuntu.

Les deux systèmes sont très efficaces, Ubuntu sans aucun doute plus léger et plus rapide, mais certains logiciels, comme inDesign ne sont pas disponibles. Certes il y a Scribus, mais ils ne sont pas compatibles entre eux et dans ma boîte, on utilise inDesign (et parfois X-press), c'est pour cela que je dois avoir un dual boot.
La politique d'Apple devenant tout de même insupportable (obsolescence très rapide des appareils et des logiciels, licences et matériel hors de prix, et même perte de la main sur les fichiers avec iPhoto, iTunes et autre iGogo) je pense que de plus en plus de fans de Mac vont se tourner vers Linux. C'est dommage parce que j'ai adoré Mac pour sa simplicité. Mais maintenant, je constate qu'Ubuntu est tout aussi facile à vivre et que la logithèque est incroyablement bien fournie.
