RESOLU - Ubuntu et MAcbook : prob de grub - RESOLU par Bougron merci !

ucem · Le 30/05/2016, à 19:14

Bonjour,

On vient de me donner un Macbook pro sur lequel il y avait installé un Ubuntu uniquement, pas de système mac, et démarrage simple après le gong de Mac sur un écran clair !

J'ai téléchargé Kubuntu 16.04 LTS 32 bits que j'ai gravé sur DVD : ok pas de soucis
Je boot avec la touche C , kubuntu live se lance, et fonctionne correctement
Donc je lance l'installation
Je crée une partition /home , une / , une swap , une ext4 pour le grub et je laisse la petite partition EFI qui existait déjà

L'installation se passe correctement mais au démarrage pas de grub !

Je tombe sur l'invite : grub>_ et là je sèche

J'ai rebouté avec supergrub 2 qui me trouve bien Kubuntu 16.04 etr qui démarre bien !

J'ai essayé avec boot repair qui me dit que mon mbr n'est pas compatible avec le efi car pas en 64 bits mais en 32bits ..... ??

Mais je ne sais pas comment faire maintenant afin de réinstaller le grub quelque part.

Quelqu'un peut il m'aider svp ?
je précise bien que il n'ya que Linux Kubuntu 16.04 d'installé , le système mac est supprimé

Bonsoir.
Tu fiches grub à la poubelle....
Tu installes la version 64 bits.
Tu utilises Refind pour booter en EFI

Bonjour
Merci de tes infos

Après l'installation de la version 64 bits, tu me dis d'utiliser refind ! Est ce bien cela dont tu parles : refind sur sourceforge !

Je ne parle pas anglais euhhh.... je l'utilise comment ce refind après l'installation de Ubuntu 64 bits ?

refind est comme supergrub 2 ? il va installer quoi ?

C'est pas clair pour moi !

Bonjour
Si ton ubuntu boote sans problème, ce n'est pas la peine d'installer refind.
Refind a les mêmes fonctions que grub, que super grub2: C'est à dire afficher les OS présents sur les supports disques et te permettre de choisir....
En fait, il remplace grubx64 ou shimx64 lorsque ceux-ci ne fonctionnent pas sous MAC. Si dans ton contexte, cela fonctionne, c'est inutile surtout que tu n'as qu'un seul OS.

ucem · Le 31/05/2016, à 14:09

ok
Je vais donc installer la version 64 bits.

Si j'ai bien compris, pendant l'installation pas la peine d'installer le grub alors !
ou
grub n'existe pas dans la version 64 bits ?

Bougron · Le 31/05/2016, à 19:12

Pendant l'installation,
Cela finira pas l'installation du GRUB et cela devrait bien se passer si tu as une partition FAT32 pour recevoir le démarrage.

Après il y a pas mal de bios qui ne veulent démarrer avec le grub... Je ne connais pas la catégorie du tien.
Mais il me semble que tous les bios apple bootent avec refind.....
Donc tu verras bien, Si cela marche parfait, Sinon, tu ne t'entêtes pas et ti installes refind. Ce qui ne sera peut-être pas facile. (un premier lancement avec supergrub2 probablement)...

Re,

J'ai installé refind .. je redémarre mais rien toujours pareil il n'y a que l'invite grub>

J'ai installé boot-repair voici le boot info :

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda4 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s repair-filesystems


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


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 16.04 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 [Réparateur de démarrage]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

vu que j'y comprend rien...
Je vais essayer de lancer boot-repair en mode réparation ...

Bonsoir

Moi aussi, j'ai du mal à comprendre. Car tu as un boot legacy....

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, but it is not setup in EFI-mode for this installed-session.

Alors que cela ressemble à une bonne installation EFI.

Que te dit cette invite grub s'il te plait?

Tu devrais certainement modifier le bios pour qu'il soit positionné en EFI Mais je ne sais pas si cela va suffire.

que faut il que je fasse ? je suis perdu ...

tu me dis :

Que te dit cette invite grub s'il te plait?

.. mais quelle invite ? Si c'est celle que j'ai à l'écran de démarrage il y a juste =>

grub >

qui attends que l'on rentre des commandes .. mais je ne sais pas quoi y rentrer !!!!!

Tu me dis aussi :

Tu devrais certainement modifier le bios pour qu'il soit positionné en EFI Mais je ne sais pas si cela va suffire

... je veux bien mais sur un Mac comment on fait pour aller dans le Bios .. je sais faire pour un PC mais pour un MAC aucune idée

Que veut dire :

Bonsoir
Cela va être dur pour moi aussi

Lorsque je t'ai posé cette question "Que te dit cette invite grub s'il te plait?", je pensais que tu allais dire qu'il y a eu quelques lignes qui s'affichaient probablement avec un message d'erreur, puis la ligne en question avec quelques infos.

La, on n'a que "grub?" et je ne sais pas d'où le boot est parti: du MBR ou de l'EFI. (Je pense EFI malgré tout)
Mais à ce niveau, il faut lui donner manuellement les infos de ubuntu installé dans la partition SDA4 du disque SDA qui est en GPT.
Tout cela avec un clavier anglais!!!!
Donc je vais certainement me tromper. J'applique une solution donnée par maxire. (en éliminant les commandes permettant de trouver SDA4 et gpt4)

set root=(hd0,gpt4)
set prefix=(hd0,gpt4)/boot/grub
linux /boot/vmlinuz  root=/dev/sda4 ro
initrd /boot/initrd.img
boot

Je ne sais pas non plus comment on fait pour passer EFI/LEGACY.

Pour le conseil de boot-repair, je suis simplement surpris que sa référence soit windows.
J'aurais préféré qu'il demande si on veut réparer en LEGACY ou en EFI ou comme il préferre..

Hello

Cela ne serait pas plus simple de re-installer ? en spécifiant bien lors de l'installation ou installer le boot-loader et indiquer la partition qui sera "Bios boot aerea" ?

D'ailleurs je ne sais pas quelle partition doit on spécifier comme "Bios boot aerea", est ce la partition efi ?
et dans ce cas ou doit être installer le boot loader ?

Bonjour
En relisant. Je comprend que :
" On vient de me donner un Macbook pro sur lequel il y avait installé un Ubuntu uniquement, pas de système mac, et démarrage simple après le gong de Mac sur un écran clair !"
C'est donc que cet ordinateur fonctionnait bien et tu l'as cassé.
Tu as fais une installation LEGACY et tu veux encore recommencer une installation LEGACY qui n'aboutira pas plus que la précédente qui est parfaite
Mais il est probable que cet ordinateur continue de booter en EFI et non en LEGACY.

Le boot-info n'a pas tout dit. Je voudrais voir le contenu d'un fichier.
Tu rebootes avec "essayer avant d'installer et tu montes la partition efi".

sudo mount   -v  /dev/sda1   /mnt

Tu donnes le contenu du fichier de configuration du grub avec la commande

sudo pg  /mnt/EFI/ubuntu/grub.cfg

Je voudrais aussi voir le nouveau contenu de cette partition.

sudo ls -Rl  /mnt/EFI

De plus, je veux savoir ce que le BIOS EFI propose comme boot. Cela va être un peu plus dur:
a) Il faut que tu installes le logiciel adéquat, la commande à faire te sera proposée en frappant:

efibootmgr

Tu exécutes ce qui est proposé puis tu donnes le résultat de la commande.

sudo efibootmgr -v

Bonjour,
Tout d'abord MERCI de ton aide .

Tu me dis :
1-

C'est donc que cet ordinateur fonctionnait bien et tu l'as cassé

. Mais non..pas cassé mais écrasé volontairement car pas de mot de passe !

2 -

Tu as fais une installation LEGACY

euhh je ne sais pas... j'ai fait une installation comme à mon habitude en installant le dvd de Kubuntu ! Je n'ai chez moi que des vieux ordi de bureau... désolé ! faut que j'évolue

Je ne savais pas qu'il y avait deux types d'installation !! Deux installation différents donc y a t'il deux dvd d'installation différents ?

3 -

Mais il est probable que cet ordinateur continue de booter en EFI et non en LEGACY.

euh....
* Il faut qu'il boot comment : efi ou legacy ?
* C'est quoi les différences ?

Est il possible de recommencer une installation mais ce coup là en EFI et non legacy ?

Est il possible sur un MAc d'accéder au bios... je crois que c'est un bios Efi mais comment y accéder.

Je vais prendre un peu de temps et répondre à tes demandes de commandes

J'ai un dvd d'install du système MAc , cela peut être utile ?

Dans ton boot-info, on voit que

boot-repair is executed in installed-session (Ubuntu 16.04 LTS, xenial, Ubuntu, x86_64)

donc tu sais booter et tu peux faire les commandes

efibootmgr

sudo mount   -v  /dev/sda1   /mnt

donc tu peux certainement faire aussi la suite que je te demande.

pour info, un boot en légacy consiste à lire le secteur 0 d'un disque préalablement sélectionné dans le bios. certainement le SDA
Il contient cela

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

 => Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 
    1050624 of the same hard drive for core.img. core.img is at this location 
    and looks for (,gpt4)/boot/grub. It also embeds following components:
    
    modules
    ---------------------------------------------------------------------------
    fshelp ext2 part_gpt biosdisk
    ---------------------------------------------------------------------------

puis cela doit continuer sur la partition GPT4 qui m'a semblé correcte

Pour info, un boot en EFI consiste à exécuter une commande parmi les 128 prévues dans la mémoire EFI.
Il n'est pas évident de savoir ce qui est prévu, c'est pour cela que je te demande de les lister avec la commande

sudo efibootmgr -v

Il est très probable que la commande prévoit l'un des fichiers contenus dans cette partition.

sda1: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.

                       /EFI/BOOT/drivers_x64/ext4_x64.efi

et que ce fichier se serve d'un fichier d'initialisation dont le contenu soit resté à l'ancienne valeur.
C'est pour cela que je te demande de fournir les 3 lignes du fichier: SDA1/EFI/ubuntu/grub.cfg

J'y reviendrais

car les partitions sont

Pour ce point-la,
"efibootmgr: EFI variables are not supported on this system".
Je ne comprends pas trop, On croyait que tu n'as pas de version 64bits EFI!

Peux-tu refaire un boot-info

ucem · Le 01/06/2016, à 17:00

Mais si mais si , tu m'as dit d'installer une 64 bits , je l'ai donc fait depuis hier

ok
Je vais donc installer la version 64 bits.

et j'ai testé des commandes de cette page https://doc.ubuntu-fr.org/uefi?redirect=1 n° 2.4 , 2.5 et 3 et donc le résultat me dit :
kubuntu démarre sur le DVD en mode NON EFI
Kubuntu est installé sur le disque dur en mode NON EFI
Kubuntu est installé en mode classique

je vais relancé un boot repair pour une boot info

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


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


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 16.04 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 [Réparateur de démarrage]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

merci

La proposition de boot-repair est à faire.

YEAHHHHHHH

MERCIIII :):lol:

IL démarre correctement !!!
un peu long mais c'est ok

Donc ce n'était que le grub.cfg qui n'était pas correct.. lors de l'installation je n'ai pas du indiquer correctement soit "bios boot aerea" et ou doit être installer le boot loader , non ?

en tout cas merci beaucoup pour ta patience, ton temps et de l'effort que tu as fait pour m'expliquer. J'ai encore besoin de comprendre beaucoup de choses.. faut que je me mette à jour avec ces histoires de EFI

Bougron · Le 01/06/2016, à 18:01

Ce n'est pas cela le problème.
Il provient de cela voir premier boot-info (échange #7)

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, but it is not setup in EFI-mode for this installed-session.
SecureBoot disabled.

à partir de cet instant, tout déraille..
Cela commence une installation LEGACY sans logiciel EFI..
Cela t'oblige à avoir une partition bios-boot

sda2: __________________________________________________________________________
    File system:       BIOS Boot partition
    Boot sector type:  Grub2's core.img
    Boot sector info:

et transfert le flag de boot sur cette partition.

Partition  Boot  Start Sector    End Sector  # of Sectors  Id System
/dev/sda1                   1     1,050,623     1,050,623  ee GPT
/dev/sda2    *      1,050,624     8,863,743     7,813,120  83 Linux

à partir de cet instant, le logiciel va croire que la partition EFI de boot n'existe pas.
et on aura ce message

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda4 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi

car le flag de boot n'est plus sur sda1.
Donc pas de mise à jour de cette partition ni du fichier présent.....

Mais, je ne sais pas ce qui vient de se passer. Peut-être le simple fait de redémarrer.
Mais maintenant on voit (second boot-info echange #21 ) que le boot est bien EFI!

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

donc tout enchaîne bien, on voit la liste de boot EFI

=================== efibootmgr -v
BootCurrent: 0000
BootOrder: 0000
Boot0000* ubuntu	HD(1,GPT,6f8f75b3-0d05-4da0-b630-b1e23f3ec03e,0x800,0x100000)/File(EFIubuntushimx64.efi)
BootFFFF* 	MemoryMapped(11,0xffcb4000,0xffffbfff)/FvFile(2b0585eb-d8b8-49a9-8b8c-e21b01aef2b7)H.D..

La liste est très faible mais on sait que c'est HD(1,GPT.... disque dur, partition 1, formatée GPT
avec uuid 6f8f.......... et fichier shimx64.efi
Reste que je ne sais pas si tu peux faire la commande.

efibootmgr

Si tu ne peux pas, ce n'est pas sain. Mais je sais qu'il existe une commande pour installer le package...
Reste qu'il faudra repositionner correctement le flag-boot sur SDA1 et supprimer la partition bios-boot (SDA2).
