[résolu] Impossible de boot windows après installation d'ubuntu
Bonsoir à toutes et à tous,
J'ai récemment décidé d'installer ubuntu sur mon pc portable, en dualboot avec windows. Je crée clé usb bootable, lance l'install, sélectionne l'install en dualboot, etc... Puis je veux repasser à windows. Et là, boum. BSOD, impossible de boot windows, erreur : INVALID BOOT DEVICE.
Après plusieurs recherches et manips, j'ai remarqué quelques choses :
- Dans Diskpart, lorsque je fais list disk, mon disque 1 (celui où les OS sont installés) n'apparaît même plus. (le deuxième disque est pour les jeux/data et est listé) MAIS je peux quand même sélectionner le disque 1.
- Un boot repair avec boot repair ne donne rien, sinon un fichier d'erreur qui me sort globalement un error code 12 lors d'un mount
- Depuis l'install ubuntu, je peux monter mon disque 1 avec la partition windows dessus, accéder aux fichiers, etc... (je joins un screen).
Je sais pas/plus quoi faire, ne m'y connaissant pas assez dans le domaine. Je pense qu'il s'agit juste d'une erreur de manip, qu'il y a "juste" à réparer les partitions de boot de windows, mais comment faire...
Merci d'avance
EDIT : le "boot info" qui peut aider (ça tombe bien on est en plein dedans)
J'ai sélectionné deux fois "non" à la demande du script de modifier/supprimer des "espaces" dans les partitions.

non, il n'y est pas. Ceci dit ubuntu marche, ça n'est pas vraiment ça le problème.

Re : [résolu] Impossible de boot windows après installation d'ubuntu
Bonjour,
As-tu essayé de choisir le disque Windows dans les options de démarrage du BIOS ?
T'es-tu renseigné sur OS-prober qui n'est pas activé ?
Tu as aussi le choix d'installer un autre lanceur d'OS.

Oui justement, lors du boot grub propose 3 options : ubuntu, ubuntu option avancées, windows boot manager. Lorsque je sélectionne ce dernier, il tente de réparer, puis erreur de réparation "impossible de réparer votre pérophérique", et j'ai le choix entre éteindre ou accéder aux options avancées.
Je connais pas du tout OS prober, je vais regarder ça.
Si tu as un autre lanceur je suis preneur ! Même si je pense pas que ce soir ça réellement le problème

classique de windows : choix entre réparation du démarrage (qui marche pas du coup), l'invite de commande, éteindre, ou d'autres menus qui ont rien à voir.
En ligne de commande j'ai tenté des choses avec bcdedit et bootrec.exe, sans succès

20_*: Third party apps (e.g. memtest86+).
The number namespace in-between is configurable by system installer and/or
administrator. For example, you can add an entry to boot another OS as
01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
the menu; and then adjust the default setting via /etc/default/grub.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p7,
using the following options: nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.3 LTS entry (nvme0n1p1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)Conseils pour les nouveaux demandeurs et pas qu'eux

Re : [résolu] Impossible de boot windows après installation d'ubuntu
Finalement, j'ai opté pour la solution forte : copier la partition C: de windows sur un dd externe, à l'aide de clonezilla (un peu long mais efficace finalement).
Ensuite, réinstall de windows de 0 (tout effacé le disque, même la config ubuntu), puis, lors de la fin de l'install, remplacer la partition C: vierge par l'ancienne qui contient les données.
C'est long et fastidieux mais ça marche.
merci à tous pour leur aide
