Dual boot non fonctionnel

Bonjour à tous,

Je poste ici après quelques recherches infructueuses concernant un problème de dual boot Windows10 / Ubuntu 18.04.

Je possédais auparavant la version 16.04 d'Ubuntu et le dual boot fonctionnait parfaitement. Malheureusement j'ai voulu passer Ubuntu en version 18.04 et le système est resté bloqué durant la mise à niveau.

Après avoir essayé de le récupérer je me suis résigné et j'ai voulu réinstaller directement la version 18.04 via un live USB.

Désormais l'affichage du Grub au démarrage est assez long à arriver. Ce n'est pas en soit gênant mais si ça peut donner un indice sur la provenance du problème... J'ai configuré 2 lignes dans le grub. La 2nd m'amène désormais sans problème sur Ubuntu. La première quant à elle devrait m'ouvrir Windows mais me provoque un message d'erreur. Si je tente de lancer directement la partition Windows via la Bios, j'obtiens un écran noir avec un tiret blanc clignotant.
Je suis conscient que mon problème ne concerne pas spécialement Ubuntu, mais mon Windows étant fonctionnel avant la réinstallation d'Ubuntu, j'ai besoin de vos lanternes.

Merci beaucoup à vous de m'avoir lu. smile

Re : Dual boot non fonctionnel

Fait un "boot-repair" avec un live cd ou usb et post le "boo-tinfo" ou l'adresse du "boot-info" et les spécialistes vont arrivés.
Mais normalement "boot-repair devrait pouvoir remettre les choses en place.

Re : Dual boot non fonctionnel

Tout d'abord merci pour votre réponse.

J'apporte donc quelques précisions sur la situation. J'avais eu comme premier réflexe l'utilisation de boot-repair lorsque mon problème était survenu.
A la suite de celui-ci, le PC s'ouvrait directement sur Ubuntu sans me proposer le Grub. J'ai donc utilisé Grub-customizer afin d'obtenir quelque chose de semblable à ce que je voulais.
Après quelques modifications, voici le boot-info que j'avais obtenu :
http://paste.ubuntu.com/p/FswD89whzN/
A cet instant j'obtenais le Grub à l'ouverture du PC mais la ligne Windows me provoquait 2 erreurs du type : "no such device..."

A la suite de votre message, j'ai décidé de refaire un boot-repair. Je suis donc revenu dans la situation initiale ou le Grub ne s'affiche pas. Voici le boot-info :

Merci. smile

Je me permets de relancer, quelqu'un peut-il me venir en aide ? J'ai cherché toute l'après-midi sans succès. neutral

Re : Dual boot non fonctionnel

Windows n'aime pas que l'on touche à son secteur de boot alors avez-vous touché à ce secteur en y installant le grub?
N'étant pas un spécialiste mais à la lecture normalement il n'y a pas pérille, les spécialistes vont regarder les boot-info et pourrons vous répondre.
A première vu windows recovery existe toujours mais est-il toujours fonctionnel? Possédez vous les outils de récupération de votre windwos, dvd ou clé usb de réparation avec une copie de votre windows?
Car une solution consiste à remettre windows en état en le réparant et à réinstaller proprement ubuntu dérrière. Mais il faut aussi se poser la question de l'UEFI ou pas à l'origine de la machine.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix customized files) and reinstall the grub2 of sda7 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 sda (ATA CT240BX200SSD1) !


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

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda7 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 sda (ATA CT240BX200SSD1) !


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

Dans les deux Boot-Info, on voit ceci :

sda4: __________________________________________________________________________

    File system:       ntfs
    Boot sector type:  Windows 8/2012: NTFS
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        /bootmgr /Windows/System32/winload.exe

Il manque la mention /Boot/BCD dans cette ligne "Boot files". C'est la raison pour laquelle, on peut vérifier que Windows n'est pas détecté dans les deux Boot-Info (seul Ubuntu est détecté) :

=================== os-prober:
/dev/sda7:L'OS actuellement utilisé - Ubuntu 18.04.1 LTS CurrentSession:linux

A mon avis, contrairement à ce que tu as écrit dans ton post #1, ton Windows n'était pas fonctionnel avant le drame. Et il n'est toujours pas fonctionnel après.

Re : Dual boot non fonctionnel

Bonjour et merci à vous deux,

Didier :
Je ne pense pas avoir touché à la partition concernant Windows lors de la réinstallation de Ubuntu.
Malheureusement ça n'arrange pas mes affaires, mais ma version Windows provient d'un programme étudiant (Microsoft Imagine) qui permet de l'obtenir gratuitement. Je n'ai donc pas de support physique, ni de support de réparation avec une sauvegarde. La meilleure option serait peut-être en effet de le réinstaller via une iso.

Malbo :
J'utilisais quotidiennement Windows avant que je me décide à réinstaller Ubuntu. Le principal problème serait donc que Windows soit détecté par le boot-info ?
Vous l'avez surement vu dans le boot-info mais il est peut-être bon de le préciser. J'utilise un ssd (sda) où les 2 OS étaient installés et un hdd (sdb) contenant toutes les données auquel j'accède depuis les 2 OS.

EDIT : En y réfléchissant et après avoir arpenter les forums, je pense avoir trouvé le problème. Je pense avoir fait la grossière erreur de toucher à des partitions de 1Mo que je pensais inutile. Si j'ai bien compris ce sont ces partitions qui servaient au boot.

Re : Dual boot non fonctionnel

Au vu du boot-info tu disposes de la partition "recovery" de ton windows alors normalement si tu ne fais pas d'erreur sur cette partition tu pourras récupérer ton windows, il suffit que tu fasses des recherches côté windows et tu trouveras comment faire.
Une fois retrouvé windows, attention, il s'installe en EFI, tu as deux issues soit tu cherches à modifier le fichiers EFI pour que tu démarres sur son menu avec une entrée pour windows et une pour ton Ubuntu ou alors tu réinstalles ubuntu derrière et là tu auras un grub qui aura ubuntu en premier et windows en choix 3. c'est ce que j'ai sur mon portable.
Attention l'EFI est pris en compte par UBUNTU à partir de la 16.04 mais il ne faut pas faire le mauvais choix au départ sinon rein au bout.
Tu peux faire le choix sans l'EFI mais apparement çà fonctionnait avant alors cela doit continuer à fonctionner.

Re : Dual boot non fonctionnel

@DidierS : la partition /dev/sda5 qui est désignée "Windows Recovery Environment (Windows)" n'est pas une partition de restauration en configuration usine comme tu le penses. Une telle partition a une taille de plusieurs Go alors que la taille de /dev/sda5 est de 506 Mo. D'après sa taille, je crois qu'il s'agit d'une petite partition créée automatiquement  lors d'une mise à niveau de Windows 10.

Re : Dual boot non fonctionnel

Oui @Malbo, je le pensais aussi car j'ai la même sur mon PC qui s'est créer lors de la mise à jour vers windows10. C'est celle là qui me permet de générer windows 10 lors des pannes car je garde cette situation jusqu'à la fin de la garantie de ce PC. Après je verrais.
