[Résolu] Boot failed après installation dual boot Kubuntu 24.10 et W10
Bonjour,
Je tente de faire démarrer un Acer Aspire E 17 sur lequel était installé Windows 10 et Kubuntu 20.04 et qui fonctionnait sans soucis.
Suite à l'installation de Kubuntu 24.10 à la place de l'ancienne version, plus rien de démarre.
Je tombe sur un cadre bleu :
"Default boot device missing or boot failed
Insert recovery media and hit any key
then select "boot manager " to choose a new boot device or boot recovery media"
Cette discussion Default boot device missing or boot failed
ressemble à mon problème mais elle est restée en suspend.
Voici le boot-info:

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would 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
Confirmation request before suggested repair: __________________________________
LegacyWindows detected. You may want to retry after deactivating the [Separate /boot/efi partition:] option.
Are you sure you want to continue anyway?
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 24.10 entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !Je précise que j'ai récemment réinstallé Kubuntu 24.10 sur un PC où la partition EFI était trop petite ce qui causait des problèmes.
En suivant les aides du forum, Kubuntu fonctionne sans problème et j'ai donc conseillé de faire la même chose sur l'Aspire E 17.
L'agrandissement de la partition EFI a été fait en faisant un formatage en FAT32 MAIS... sans avoir fait les sauvegardes préalables de cette partition !
Je soupçonne donc que le problème vienne de là.
Merci d'avance pour vos conseils.

Re : [Résolu] Boot failed après installation dual boot Kubuntu 24.10 et W10
Bonjour.
Ordinateur ACER,
Le boot-indique secure-boot déactivé.
Il faut autoriser à booter
Soit EFI/refind/refind_x64.efi
Soit EFI/ubuntu/grubx64.efi.
Si tu décides de réactiver le sécure-boot, le fichier à utiliser devient EFI/ubuntu/shimx64.efi.
voir cet échange.

Re : [Résolu] Boot failed après installation dual boot Kubuntu 24.10 et W10
Bonjour,
Merci Geole, Kubuntu démarre grâce à tes conseils.
Dans le bios :
- J'ai remis le boot secure enable
- Dans l'onglet security je suis allé dans select UEFI file as trusted
HDD0 (entrée) <ubuntu> (entrée) shimx64.efi (entrée)
- S'ouvre alors un carré bleu qui demande "do you wish to add this file to allowable database? Boot description (j'ai entré Kubuntu24)"
- J'ai cliqué sur yes
- Dans l'onglet Boot, j'ai mis en 1 EFI| File boot 3: kubuntu24
- F10 pour sauver
A présent, le PC démarre directement en Kubuntu.
Il faudra que je me procure une clé USB d'installation de W10 pour suivre les conseils des liens indiqués dans ton message.
C'est moins urgent, je clos donc la discussion.
