[Résolu] SecureBoot disabled - Platform is in Setup Mode
Bonjour toul'monde !
Je crois que j'ai fait une boulette... mais je n'en suis pas sûr. Explication :
Sur un PC portable Asus avec son "Secure-Boot" désactivé, j'ai installé sur une clé USB un Debian-Facile 13.
L'installation s'est bien passée et cette clé USB Debian fonctionne bien sur cet Asus.
J'ai testé ensuite cette clé USB Debian sur mon PC principal [Gigabyte B760M DS3H AX] avec Xubuntu + Windows11, et elle fonctionne également.
Après ça j'ai vérifié le "Secure-boot" sur ce PC principal en mode Xubuntu et là :
poun@Gigapoun-2404:~$ sudo mokutil --sb-state
[sudo] Mot de passe de poun :
SecureBoot disabled
Platform is in Setup ModePuis :
poun@Gigapoun-2404:~$ mokutil -l

poun@Gigapoun-2404:~$Sous Windows 11, le "Secure-Boot" est également désactivé.
Avant le test de cette clé sur ce PC principal, il me semble que le "Secure-boot" était actif mais je ne peux pas le certifier...
Du reste, pour que Windows 11 s'installe, il faut bien que le TPM et le "Sécure-boot" soient actifs.
J'ai installé mes Xubuntu 24.04 dans un deuxième temps.
Il y a-t-il un rapport entre le lancement de cette clé USB Debian, ou ce problème de "Secure-boot" est-il antérieur à ça ?
Dans le BIOS concernant le "Secure-Boot", les paramètres actuels sont les suivants :
- System Mode = Configuration et pas en mode "Setup"
- Secure Boot = Activation
- Secure Boot Mode = Standard
Je me suis permis de réinitialiser les paramètres Bios, à partir d'une sauvegarde faite il y a quelques mois, et c'est pareil.
J'ai trouvé ce lien : https://www.malekal.com/resoudre-secure … user-mode/
Mais j'ai peur de tout perdre... Je ne suis pas du tout à l'aise avec ça...
Merci pour tous vos conseils...

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda2,
using the following options: sda1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 24.04.3 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)1) Xubuntu 24.04._LTS + Windows 11 - Gigabyte B760M DS3H AX - Intel Core i5-12600K / UHD Graphics 770 intégré - 10 cœurs -3,7 Ghz - 32 Go de RAM

Re : [Résolu] SecureBoot disabled - Platform is in Setup Mode
Bonsoir.
Si tu souhaites réactiver le secure boot, il faut que tu le fasses depuis le bios.
Ton boot-info montre que shimx64.efi ( gestionnaire du boot sécurisé ) est bien prévu.

Re : [Résolu] SecureBoot disabled - Platform is in Setup Mode
Bonsoir toul'monde !
Merci Geole et Iznobe pour vos retours.
La solution était vraiment dans les réglages du BIOS au niveau du "Secure Boot".
Avant modification, le System Mode était bien sur "Configuration", peut-être suite à un "Retour aux paramètres par défaut" précédent...
En image, ça donnait ceci : 
Pour quitter ce mode "Configuration", j'ai restauré les clés d'usine "Restore factory keys" et le System Mode est passé en mode "Deployed".
Maintenant en image ça donne ceci : 
Sous Xubuntu, le "Secure Boot" est maintenant actif :
poun@Gigapoun-2404:~$ sudo mokutil --sb-state
[sudo] Mot de passe de poun :
SecureBoot enabled
poun@Gigapoun-2404:~$ Sous Windows 11, dans "Informations Système => Rubrique "Résumé Système" je lis :
État du démarrage sécurisé = ActivéPour revalider ma clé Ventoy, j'ai utilisé ce tuto : https://www.technewstoday.com/ventoy-secure-boot/
Je passe donc mon sujet en résolu.

Re : [Résolu] SecureBoot disabled - Platform is in Setup Mode
WBonsoir.
A vérifier. Mais il me semble que le shim utilisé par ventoy est celui utilisé par Ubuntu et windows..
Donc, le premier qui se présente fait le boulot pour tout le monde.
