[RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

Bonjour bonsoir,
je rencontre un problème de boot sur mon PC depuis aujourd'hui (dual boot auparavant très stable).
Dans le menu GRUB, quand je sélectionne Win, apparaît ce message :

erreur : fichier "/efi/Microsoft/Boot/bootmgfw.efi" non disponible

A priori je n'ai rien modifié, récemment, mais Win à fait quelques mises à jour importantes récemment.
J'ai toujours accès à mon disque Win, sur lequel j'ai trouvé sans peine le fichier que Grub ne trouve pas...

Je colle mon boot-info :

OK, entre temps je me suis qu'il suffisait peut être de faire un

sudo update-grub

pensant que grub relocaliserait le fichier idoine...
Résultat : disparition de Win dans le menu de grub.

Bonjour,

Pourquoi poster ce message avec un compte différent alors que tu possèdes déjà le compte Rappa ?

Quand je fais réparation recommandée avec l'outil boot repair j'obtiens ce message :

GPT détecté. Veuillez créer une partition BIOS-Boot (>1MB, système de fichiers non formaté, drapeau bios_grub). Cela peut être réalisé via des outils tels que Gparted. Puis réessayez.
Alternativement, vous pouvez ré-essayer après avoir activé l'option [Partition /boot/efi séparée :].

Que je ne comprends pas.

(debug) reinstall grub2 place-in-all-MBRs no-BIOS_boot (sdb2)


=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages fix legacy files) and reinstall the grub2 of sdb2 into the MBRs of all disks (except USB 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


=================== Blockers in case of suggested repair
GPT détecté. Veuillez créer une partition BIOS-Boot (>1MB, système de fichiers non formaté, drapeau bios_grub). Cela peut être réalisé via des outils tels que Gparted. Puis réessayez.
Alternativement, vous pouvez ré-essayer après avoir activé l'option [Partition /boot/efi séparée :].


=================== Advice in case of suggested repair
EFI détecté. Vous souhaiterez peut-être ré-essayer après avoir activé l'option [Partition /boot/efi séparée :].
Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdb (1000GB) ! Veuillez désactiver SecureBoot dans le BIOS.


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

On y voit que ton Windows n'est plus détecté(*). Je te conseille de déconnecter physiquement ton disque dur de 1 To pour ne laisser que le SSD de 120 Go (afin d'éviter de faire des conneries). Puis de réparer le démarrage de Windows avec l'aide d'un forum Windows si tu ne sais pas faire. Quand tu auras réussi à refaire fonctionner ton Windows 10, tu pourras reconnecter ton disque de 1 To et tu devrais pouvoir retrouver le démarrage par défaut sur le menu Grub en intervenant dans le "Bios" pour remettre Ubuntu en priorité de démarrage.

(*) c'est justement parce qu'il n'est plus détecté qu'il a disparu du menu Grub quand tu as passé la commande de mise à jour de Grub (sudo update-grub)

Salut,

Tout est dit par malbo.... As-tu un DVD/USB d'installation ou de réparation de W10 sous la main ?

Merci pour réponses.
J'ai gardé le DVD d'install Win je crois oui, je vais voir ce que je peux faire. J'espère que je pourrais restaurer sans trop de pertes.
Il faudrait quand même que j'identifie la cause du problème, en espérant que ce ne soit pas mon SSD qui soit en train de lâcher.

Une fois restauré Win, il me suffira de faire une mise à jour de Grub pour qu'il le retrouve ?

Je vous tiens au courant dès que j'aurais eu le temps de m'occuper de ça (pas aujourd'hui malheureusement).

Re : [RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

Il faudrait quand même que j'identifie la cause du problème,

Elle est ici, la cause. La partition efi ne contient plus le moindre fichier de démarrage de Windows :

sda2: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:  

     

ll n'y a pas besoin de restaurer. Tu débranches le disque dur pour ne garder que le ssd. Tu lances le dvd d'installation en mode "réparer l'ordinateur" et tu vas jusqu'à l'invite de commandes et tu tapes

diskpart
list vol
exit

Tu repères la lettres de ton Windows. Par exemple, C (tu adaptes à ton cas). et là, tu tapes

bcdboot c:\windows /l fr-fr

Ton Windows doit démarrer. Si oui, il faudra rebrancher le HD, démarrer sur Linux, et refaire un

sudo update-grub

Re : [RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

Bonjour
je pense que vous avez fait une erreur d'analyse du boot-info

Souvenez-vous. Dans l'ensemble le grub ne sait regarder que dans le disque SDA...
Ici on  voit que dans la partition de démarrage du disque SDA qui est défini GPT, il n'y a absolument rien

sda2: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        
sda3: _______________________

Alors que dans le disque SDB qui est aussi défini GPT, il y a absolument tout

sdb1: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        /EFI/Boot/bootx64.efi /EFI/ubuntu/MokManager.efi 
                       /EFI/ubuntu/fwupx64.efi /EFI/ubuntu/grubx64.efi 
                       /EFI/ubuntu/shimx64.efi 
                       /EFI/Microsoft/Boot/bootmgfw.efi 
/EFI/Microsoft/Boot/bootx64.efi

On voit aussi que l'ancien windows était dans SDA alors qu'il est maintenant dans SDB

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager (sur /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-efi-B66D-E053' {
	insmod part_gpt
	insmod fat
	set root='hd0,gpt2'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2  B66D-E053
	else
	  search --no-floppy --fs-uuid --set=root B66D-E053
	fi
	chainloader /efi/Microsoft/Boot/bootmgfw.efi

Donc une recherche dans la partition B66D-E053   qui est actuellement inexistante

On voit aussi ceci

=================== efibootmgr -v
BootCurrent: 0003
Timeout: 3 seconds
BootOrder: 0003,0001,0004,0000
Boot0000  Windows Boot Manager	HD(2,GPT,4443f7a2-984e-4c03-a272-78b8e76752e7,0xe1800,0x32000)/File(EFIMicrosoftBootbootmgfw.efi)WINDOWS.........x...B.C.D.O.B.J.E.C.T.=.

Windows et ubuntu n'ont jamais été dans la même partition

Je propose
A)  Transformer la partition SDA2 en NTFS puis

sudo os-prober

Si windows détecté, il suffit d'un update du grub. Si pas détecté:
B) il faut la remettre en FAT32 et dupliquer le contenu de la partition SDB1 dans la partition SDA2
Puis

sudo grub-install
sudo update-grub

L'explication la plus simple qui me vient à l'esprit est un débranchement des câbles et un rebranchement a des endroits différents ou avec une permutation qui s'est faite à un moment donné. Puis la mise a jour importante de windows a fait du ménage dans SDA2.

A noter que vu la taille de SDB1

sdb1 part vfat 512M

Ce n'est pas du standard windows.

Re : [RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

Quand je fais réparation recommandée avec l'outil boot repair j'obtiens ce message :

GPT détecté. Veuillez créer une partition BIOS-Boot (>1MB, système de fichiers non formaté, drapeau bios_grub). Cela peut être réalisé via des outils tels que Gparted. Puis réessayez.
Alternativement, vous pouvez ré-essayer après avoir activé l'option [Partition /boot/efi séparée :].

Que je ne comprends pas.

Bonjour
Cela est un message que tu as lorsque tu veux utiliser boot-repair en bootant en mode LEGACY et non EFI.

ikewdu

Re : [RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

Re,

Moi, je vois bel et bien un Windows ici :

sda4:   Boot sector type:  Windows 8/2012: NTFS
 Boot files:        /bootmgr /Windows/System32/winload.exe

/dev/sdb4      fuseblk   867G  115G  752G  14% /mnt/boot-sav/sdb4

Et comme tu l'as dit, la partition sda2 (partition efi en fat32) est vide. Donc, je réparerais déjà le démarrage de ce Windows pour le rendre fonctionnel de manière autonome. Windows n'aime pas beaucoup les partitions efi déportées vers un autre disque. D'autant plusqu'on ne sait pas si les fichiers efi sur sdb1 n'ont pas été ajoutés artificiellement par une réparation faite avec BR (et ça sent très fort de ce côté là).

Bref, comme le conseille malbo, je réparerais le premier disque pour que Ws fonctionne, et après, on voit ce que ça donne sur un dual-boot.

Que je ne comprends pas.

Tu as deux modes de démarrage possibles:
- mode bios
- mode uefi

Pour un démarrage en mode bios il faut les éléments suivants, grub-pc dans le mbr du disque et core.img (qui occupe environ 32 ko). Dans un disque avec partitionnement msdos, core.img est dans la zone comprise entre le mbr et la première partition. Avec un disque gpt cet espace est déjà occupé et il faut créer une partition sans système de fichiers pour loger core.img : c'est la partition avec le flag bios_grub (ou bios boot)

Pour un démarrage en mode uefi - et quel que soit le type de table des partitions, il faut une partition EFI (en fait une partition FAT avec le drapeau efi ou esp) pour recevoir les fichiers .efi.
grub-pc n'a pas besoin d'être installé dans le mbr car non utilisé dans ce mode de démarrage.

Non. J'ai pas ouvert ma tour depuis quelques temps déjà.
Je pense plutôt que lors des dernières maj Win a déplacé un fichier de démarrage, que Grub n'a pas retrouvé.
Et qu'ensuite boot-repair à collé un fichier de boot Win sur le mauvais disque.

Enfin, merci à tous pour vos conseils.
Je vais m'en occuper, je viendrai ici pour pour signifier ma réussite... ou solliciter de nouveaux conseils.
Je vais commencer par faire ce que propose ikwedu, ça me paraît être le plus logique.

Re : [RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

Bon la commande proposée par ikwedu ne fonctionne malheureusement pas. Message d'erreur :

(Et désolé pour le multi, je suis sur mon tél)

Il faudrait faire le point... Es-tu sûr d'avoir fait booter ton USB /DVD de réparation en mode uefi ? Si oui, donne le résultat de

diskpart
list disk
sel disk 0

list part

Bon c'est à n'y comprendre :
j'allais me résoudre à une restauration système (avec perte de toutes mes applis Win), juste avant j'essaie une nouvelle fois ta commande et... ça marche !
Merci ikewdu donc, mes deux systèmes fonctionnent.
Je fais la mise à jour de Grub et si tout roule, je pourrais passer le sujet en résolu.

Re : [RÉSOLU] Problème GRUB dual boot ubuntu 16.04/Win10

OK, tout est rentré dans l'ordre, le commande :

 sudo update-grub 

a permis à Grub de retrouver Win sans problème.
Me voilà donc à nouveau avec un dual boot fonctionnel.

Merci à tous les contributeurs, c'est toujours un plaisir de constater la compétence et la réactivité des usagers de ce forum.

C'est donc la commande "bcdboot c:\windows /l fr-fr" proposée par ikewdu dans le post #9 qui a pu réparer ton Windows.
Pour qu'on puisse voir l'état final, je te prie de faire un Boot-Info depuis une session de ton Ubuntu installé et donner l'URL de ce Boot-Info dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to sign-grub fix legacy files) and reinstall the grub-efi-amd64-signed of sdb2, using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Advice in case of suggested repair
Veuillez désactiver SecureBoot dans le BIOS. Puis réessayez.Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdb (1000GB) !

Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

paste.debian.net ko (), using paste2

Tout me semble parfaitement remis en ordre.
Il y a quelque chose qui m'intrigue : dans le Boot-Info du post #6, on peut voir :

sdb1: __________________________________________________________________________

    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        /EFI/Boot/bootx64.efi /EFI/ubuntu/MokManager.efi 
                       /EFI/ubuntu/fwupx64.efi /EFI/ubuntu/grubx64.efi 
                       /EFI/ubuntu/shimx64.efi 
                       /EFI/Microsoft/Boot/bootmgfw.efi 
                       /EFI/Microsoft/Boot/bootx64.efi

Alors que dans le dernier Boot-Info que j'ai collé ci-dessus, on a :

sdb1: __________________________________________________________________________

    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        /EFI/ubuntu/MokManager.efi /EFI/ubuntu/fwupx64.efi 
                       /EFI/ubuntu/grubx64.efi /EFI/ubuntu/shimx64.efi

Est-ce que c'est toi qui a fait le ménage à la main pour supprimer /EFI/Boot/bootx64.efi , /EFI/Microsoft/Boot/bootmgfw.efi et /EFI/Microsoft/Boot/bootx64.efi ? Sinon, as-tu une explication là-dessus ?

Non je n'ai rien fait "à la main", et je suis bien incapable d'expliquer la disparition de ces fichiers.
Après mon premier boot-info j'ai fait un boot-repair, qui n'a pas abouti (message d'erreur) ; et un update-grub (mais là je ne pense pas qu'il y ait de rapport)

Tu repères la lettres de ton Windows. Par exemple, C (tu adaptes à ton cas). et là, tu tapes

bcdboot c:\windows /l fr-fr

Ton Windows doit démarrer.

Il est probable que la mise à jour de windows a choisi d'imposer la seconde partition qui est celle contenant la stucture actuelle de boot EFI en faisant basculer la structure de boot.

C'est plus ou moins bien expliqué dans la doc windows  => https://technet.microsoft.com/fr-fr/lib … 2147217396

BCDboot copie les fichiers dans la partition système par défaut identifiée par le microprogramme. Vous pouvez créer cette partition à l’aide d’un outil de partitionnement, tel que DiskPart. Il n’est pas nécessaire d’attribuer une lettre de lecteur à cette partition pour que BCDboot puisse la localiser.

    Sur les systèmes Unified Extensible Firmware Interface (UEFI), la partition système EFI est la partition système sur les disques utilisant le format de disque de table de partition GUID (GPT). BCDboot crée le répertoire \Efi\Microsoft\Boot et copie tous les fichiers d’environnement de démarrage requis dans ce répertoire.

BCDboot peut mettre à jour un environnement de démarrage existant sur la partition système. Les versions de fichiers plus récentes provenant de l’image système Windows seront copiées dans la partition système.

Si un magasin BCD existe déjà sur la partition système :
    BCDboot crée une nouvelle entrée de démarrage dans le magasin BCD existant, en fonction des paramètres figurant dans le fichier BCD-Template, et supprime les éventuelles entrées de démarrage en double qui font référence à la même image système Windows.

Donc, le problème reviendra de nouveau. La solution est bien que  os-prober accepte  de rechercher les partitions efi et non regarder dans SDA s'il existe une partition EFI.
D'ailleurs, il semble que seul ubuntu a ce comportement sectaire.
De plus lorsqu'on rencontre une partition EFI verrouillée par constructeur, c'est la panique...... alors qu'on peut en avoir jusqu'à 128 par disque

La partition systeme par défaut est:
Selon la spécification UEFI 2.3.1, les paramètres de microprogramme par défaut doivent ouvrir le fichier \efi\boot\bootx64.efi dans la partition système EFI.     Cela ne sera pas facile de savoir si initialement ce fichier était dans la partition SDA1

 bcdboot  \windows...

Cette commande ne fonctionnera jamais. Il faut nécessairement indiquer la source de la copie. Je l'utilise très souvent et je la connais bien.  Ce qui est dit ici concerne non pas la source mais la cible :

BCDboot copie les fichiers dans la partition système par défaut identifiée par le microprogramme
Il n’est pas nécessaire d’attribuer une lettre de lecteur à cette partition pour que BCDboot puisse la localiser.

Ca signifie qu'on peut taper à minima (j'enlève les langues):

bcdboot c:\windows 

pour faire la même chose que...

bcdboot c:\windows  /s z:

... si Z est la partition système.

Rappa s'est sûrement trompé la première fois. Quant aux fichiers disparus, je suis comme Malbo, je ne me l'explique pas.
