[Résolu] Ubuntu 22.04 grub ne trouve pas windows

Bonjour à toutes et à tous

je galère depuis deux jours.
Sur un portable Akoya i3 avec windows 10 déjà installé, j'ai installé Ubuntu 22.04.
Opération que j'ai réalisée sans soucis à plusieurs reprises sur différentes machines.
Cette fois-ci le grub ne trouve pas windows.
j'ai fait le tour de tous les posts sur le sujet (notamment celui-ci où Nany a trouvé une réponse):
forum.ubuntu-fr.org//viewtopic.php?id=2073491mais sans trouver de solution.
J'ai ajouté

GRUB_DISABLE_OS_PROBER=false

dans

/etc/default/grub

vu que maintenant sur la 22.04 il est désactivé
mais le

sudo os-prober

ne trouve toujours pas win10.
J'ai essayé de corriger le grub avec recovery disk qui m'a dit qu'il l'avait corrigé et au démarrage suivant il y eu une ligne "Windows Boot Manager sur sda1" mais le clic a signalé une erreur.
Au démarrage suivant cette ligne avait disparu.
Voici le boot-info généré par boot repair:
http://paste.ubuntu.com/p/5w3bqMjPV6

Et voici deux retours:

iannis@iannis-Akoya-E6416-MD99580:~$ sudo os-prober
iannis@iannis-Akoya-E6416-MD99580:~$ 

iannis@iannis-Akoya-E6416-MD99580:~$ sudo update-grub

Merci pour votre aide

Unhide GRUB boot menu in sda5/boot/grub/grub.cfg

Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.1 LTS entry (sda1/efi/ubuntu/grubx64.efi 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\ubuntu\grubx64.efi

Re : [Résolu] Ubuntu 22.04 grub ne trouve pas windows

Bonjour , si " os-prober " ne detecte pas windows , il y a de grandes chances que c ' est parceque tu as une installation en demarrage
UEFI et l' autre en MSDOS .
pour s' en assurer fournit un boot-info st p .

Re : [Résolu] Ubuntu 22.04 grub ne trouve pas windows

un boot -info , donne les infos , un boot-repair donne les infos sur la reparation presumée bonne effectuée .
on n' y voit pas les meme choses , et on ne fait un boot-repair que lorsqu ' on est certain que la reparation a faire est bien la bonne .
si ca nefonctionne toujours pas , c ' est que ca servait a rien de faire un boot-repair ...

Et on ne pourra resoudre le soucis sans le boot-info .

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub-efi of
sda5,
using the following options:  sda1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups

Blockers in case of suggested repair: __________________________________________

WindowsEFI detected. Please disable BIOS-compatibility/CSM/Legacy mode in your UEFI firmware, and use this software from a live-CD (or live-USB) that is compatible with UEFI booting mode. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode. 

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.2 LTS entry (sda1/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)
The boot of your PC is in BIOS-compatibility/CSM/Legacy mode. You may want to retry after changing it to UEFI mode.

j ' ai envie de dire que les resultats des courses etait bien la suspicion de depart , mais @geole etant plus expert que moi , il est preferable d' avoir son avis .

Re : [Résolu] Ubuntu 22.04 grub ne trouve pas windows

Il ne faut pas booter en mode LEGACY......
Rectifie le bios..... Au besoin, publie des captures d'écran du bios.

Grand merci geole.
Ça marche !

Pour ceux qui auraient le même problème:
J'ai mis Fast Boot désactivé
et
CSM Support activé

Re : [Résolu] Ubuntu 22.04 grub ne trouve pas windows

CSM , c ' est pas bien , il faut mettre soit UEFI , soit LEGACY . dans ton cas ca semblerait etre UEFI donc , et modifier ubuuntu si besoin pour qu ' il demarre en mode EFI .
