Re : SOS - dual boot: plus d'accès à Windows

OK.

Repasse le PC en uefi: reboote sur Ubuntu, et depuis un terminal, tente un

sudo update-grub

L'entrée "Windows" devrait s'ajouter à GRUB. Il restera à tester si tout ça fonctionne.

Re : SOS - dual boot: plus d'accès à Windows

ça marche wink

Merci à tous pour votre sérieux, votre patience et votre disponibilité.
C'est vraiment super, la façon dont vous faites profiter les autres de vos compétences.
J'essaierai de ne plus faire de bêtises avec Ubuntu !

Bon week-end à tous,
Merciiiiiii

Re : SOS - dual boot: plus d'accès à Windows

Re,

Pourrais-tu nous proposer un nouveau rapport boot-info ?

Un Windows Legacy sur disque dos qui tourne en uefi, ça mérite d'être mis en mémoire, ne serait-ce que pour d'autres qui seraient confrontés à ce genre de situation. Et ça évitera de devoir palabrer avec tel ou tel qui prétendrait qu'on ne peut pas le faire.

Je plusoie...
J'ai fais partie des septiques pour Windows...

Édit;
Chez moi. Avec une clé de tests en GPT. Un Os installé en UEFI, puis réinstallation de Grub en Bios_Legacy. Il démarre dans les deux modes Bios_Legacy et UEFI.
Il y a sur le SSD interne de la machine, en MSDos,un Windows7, un Ubuntu 14.04 en 32 bits, un Ubuntu 18.04 que j'arrive à lancer en mode UEFI depuis la clé de tests à partir du Grub de L'Os (après une maj de grub) démarré en UEFI. Je savais que l'on pouvait démarrer les Linux dans les deux modes, même les 32 bits. Mais pas mon Windows 7.

Lors des manips proposées par ikewdu, j'ai démarré la machine sur Windows 7, branché la clé de tests, elle n'est même pas vue, je ne peux donc pas tester le lancement de mon Windows installé en Bios_Legacy, via l'UEFI de la clé de tests.

Re-Édit;
Si si, elle est vue dans le gestionnaire des disques. Plus-tard, à mon retour, je vais tester la manip...

Re-re-Édit;

La clé de tests (60 Go) est vu comme disk 1,  la partition efi est la partition 1;

/usr/share/boot-sav/gui-tab-other.sh: ligne 93: _checkbutton_repairfilesystems : commande introuvable


=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb6, using the following options:        sdb5/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s repair-filesystems  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 fichier sdb5/efi/.../grub*.efi !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 19.04] 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/efi (FAT32, 100MB~250MB, en début de disque, drapeau boot). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot/efi séparée :] de [Boot-Repair].

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.

Bonjour,

excuse-moi, je pensais que l'URL suffisait.
Peut-être qu'elle ne reste pas disponible très longtemps ?

Re : SOS - dual boot: plus d'accès à Windows

Salut,
J'ai un problème similaire. Win10 fraîchement installé, puis installation de Ubuntu Studio et impossible d'accéder à Win10...
J'ai l'impression que je devrais tenter de réparer le MBR mais je ne comprends pas comment lancer la session live en bios_legacy.
Du coup avant de refaire n'importe quoi, je poste ici dans l'espoir de trouver un peu d'aide.

Voici le boot-info:

================================= User choice ==================================

Is sdb (ATA Hitachi HDS72161) a removable disk? no

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub2 of
sdb2 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: legacy-win no-win-efi 
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix     

Blockers in case of suggested repair: __________________________________________

 GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again.
Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.

Confirmation request before suggested repair: __________________________________

You may want to retry after mounting your encrypted partitions so that the tool can verify their contents. (https://help.ubuntu.com/community/EncryptedPrivateDirectory)
Are you sure you want to continue anyway?

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your BIOS boot on sdb (ATA Hitachi HDS72161) disk!

Merci!

Re : SOS - dual boot: plus d'accès à Windows

Bonjour,
Ton boot-info montre qu'en standard, cela boote en legacy et la réparation legacy est prévue. Donc
1) Boote avec le support d'installation et vérifie que tu n'as pas booté en EFI avec cette commande

[ -d /sys/firmware/efi ] && echo "Session EFI" || echo "Session non-EFI"

2) Lance gparted.
3) Mets le drapeau bios_grub sur la partition sdb1( Celle qui a actuellement le drapeau esp)
4) Installe boot-repair
5) Fais la réparation recommandée.

Re : SOS - dual boot: plus d'accès à Windows

Excellent, merci beaucoup!!!
Eh ben ça marche maintenant! Ouah ça fait du bien smile
Question de curiosité, et pour d'autres personnes qui pourraient avoir le même problème:
Si j'avais remarqué que j'avais booté en EFI, j'aurais dû faire quoi?
Merci encore!

Aller régler le bios pour faire booter en legacy. Probablemement quelques tatonnements.
