Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub-efi of
sdb2,
using the following options:  sda2/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 22.10 entry (sda2/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)

3) Refind est installé et il n'est pas utilisé
    Que faire?  l'utiliser? le supprimer?

4)   Des entrées EFI sont régulièrement  ajoutées dans la RAM. Il y certainement quelque chose qui ne va pas.

Re : [RÉSOLU] Multi boot qui ne fonctionne plus - Rapport Boot-Repair

@ geole Merci pour ton support !
J'ai exécuté toutes les commandes suggérées et malgré cela, il faut que je boot avec F11, l'ordre des boot proposés a changé et c'est mieux.
Je n'ai cependant pas de boot automatique.
Faut-il refaire Boot-info ?

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub-efi of
sdb2,
using the following options:  sda2/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 22.10 entry (sda2/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)

Re : [RÉSOLU] Multi boot qui ne fonctionne plus - Rapport Boot-Repair

Oui à deux titres
1) La version de ton bios est E7B45IMS.AA0      donc le fichier de référence ne convient pas  car E7B45Vxx
2) On voit que ton bios est positionné prioritairement en LEGACY alors que les fichiers de boot sont en EFI
    Mais, je ne sais pas du tout comment  faire le changement,,   Appuie sur la touche F7 pour voir ce qui va être proposé.

Je note cela.... Il fallait y  penser

Why the BIOS version in BIOS setup menu is different from the version on the website?
LastUpdate : Wed, 11 Apr 2018
Answer

They are the same version. For example, the version on the website is 7B58v11 and it shows E7B58IMS.110 in BIOS setup menu.

Si je traduis bien E7B45IMS.AA0   > 7B45vaa ??
Donc,  tu aurais au moins une  version  en attente d'installation.....
Ta version actuelle:
AMI BIOS 7B45vAA    2020-01-108.06 MB   -  Update Microcode.   -  Improved TPM function.

Celle  qui apporte des améliorations:
AMI BIOS7B45vAB      2020-06-108.07 MB   -  Improved memory compatibility.  -  Update Intel Micro code for security vulnerabilities

Celle qui va supporter windows  11.   A toi de savoir si tu vas  utiliser windows11.

D’après le boot-info, l’ordre serait bon.

Pas trop surprenant que cela plante lorsque tu sélectionnes EFI ==> Regarde le ligne du bas qui liste les périphériques EFI, elle n’affiche rien.

Merci de dire si cette commande permet de mettre ubuntu en début de liste et si c'est stable. Si oui, Il reste à comprendre pourquoi le boot ne peut pas se faire automatiquement.

Re : [RÉSOLU] Multi boot qui ne fonctionne plus - Rapport Boot-Repair

C'est un peu ce que je craignais.
Je pense qu'il y a trois pistes
- Rester en l'état et demander à windows de faire la proposition de boot .

For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi 

Traduction:   Sous windows, lancer l'application powershell (admin)   et faire un copier/coller de cette commande

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi  

ou si mauvaise codification

bcdedit /set '{bootmgr}' path \EFI\ubuntu\grubx64.efi  

- Installer refind en live USB   avec le script indiqué au paragraphe 2.1.2 et en disant de finaliser avec un écrasement de la structure de boot de windows qui sera sauvegardée.
- Procéder à une mise à jour du bios version +1 en espérant une amélioration de cette séquence.

Re : [RÉSOLU] Multi boot qui ne fonctionne plus - Rapport Boot-Repair

Bonjour .

Deja il serait bon de mettre a jour le BIOS avec la derniere version en date ( 2 versions de retard ) .

Pour parametrer ubuntu en priorité 1 de disque de demarrage , le plus simple est encore de passer par le BIOS vu qu ' avec efibootmgr ca ne veut pas .

il faudrait etre cependant certain qu ' ubuntu et windows sont installés dans le meme mode demarrage et si oui lequel .
il faut aussi savoir si ubuntu et windows sont sur le meme disque dur ou pas .

d ' apres ce retour :

BootOrder: 0005,0004
Boot0004* Windows Boot Manager	HD(2,GPT,51fe7025-5c5f-4e7d-9688-e7dbb9cde4d9,0x1000,0x3f800)/File(\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI)..BO
Boot0005* ubuntu	HD(2,GPT,4eb0104e-e8a8-433d-aac7-51d164e1afab,0xfa000,0x32000)/File(\EFI\UBUNTU\GRUBX64.EFI)

j ' en deduis que windows et ubuntu sont installés en EFI et sont sur le meme disque .
je demande confirmation a geole en passant ...

si oui , dans le BIOS , il faut alors modifier plusieurs choses simultanement .
Deja , il faut evidemment forcer le mode de demarrage EFI ( dans : " boot mode select " ) , puis , desuite apres et juste en dessous modifier l ' ordre des peripheriques de boot afin d' obtenir la liste suivante :
UEFI USB KEY
UEFI CD/DVD
UEFI HARD DISK DRIVES
puis pour la suite de la liste , mettre tout ce qui ne commence pas par UEFI , par exemple USB KEY etc ..

ensuite , te rendre dans l ' onglet " BOOT " et selectionner le bon peripherique de demarrage comme on le voit sur cette photo : https://postlmg.cc/30QSkwNs
tu click sur " windows boot manager " , puis dans la liste qui apparaitra , tu cliques sur " ubuntu P0 CRUCIAL " , cela aura pour effet d' inverser les 2 , donc ubuntu passera en 1er et windows en 2eme .

tu appuies alors sur F10 pour sauvegarder les changements .

MAIS : le soucis c ' est que d' apres ce que l' on voit sur la photo suivante https://postlmg.cc/30QSkwNs , c ' est que tu n ' as pas seulement :

Doc Brown a écrit :

sda1
sda2
sda4 =>  Windows 10
sdb1 => UBUNTU 22.04 LTS
sdb2 => UBUNTU 22.10
sdb3 =>  Données Ubuntu /home
sdc2
sdc3 =>  1- Données Windows
sdd4 =>  2- Données Windows

il y apparait des entrés en double , on voit 2 fois windows et 2 fois ubuntu , ca n' est pas normal , il faudrait d' abord corriger cela !
je ne sais pas si c' est du a la presence de refind et de grub simultanement ou autre chose , mais il faut d' abord rectifier cela avant toute manip .

Toi tu dis que windows et un des 2 ubuntu ne sont pas installés sur le meme disque . ce n' est pas ce que montre le retour ci-dessus , le retour montre que windows et un des 2 ubuntu sont installés sur le disque hd2 probablement le disque sdb .
un autre ubuntu est installé sur le disque a plateau western digital .

De plus , depuis la 22.04 , afin d' avoir un multiboot , il faut activer la detection des OS via le fichier /etc/default/grub manuellement , pour commencer donc , commence par nous donner le contenu de ce fichier de l' ubuntu avec lequel tu desires demarrer en priorité :

cat /etc/default/grub

Autre point : il y aurait 3 systemes differents a traiter : windobs , ubu 22.04 et ubu 22.10 , donc une ligne efibootmgr a 3 entrées . A mon avis il y a au moins un des 3 OS qui n' est pas installé en EFI . faudrait que j' analyse le boot info plus en details ...

Pour en faire la synthèse, j'ai fait la photo Boot.png
Avec F11, j'obtiens le choix des boot
puis avec le choix 1 (en rouge) démarrage de Windows
avec le choix 2 (en rouge) menu de grub où je peux démarrer les ubuntu ainsi que windows.

C'est ce choix 2 (en rouge) que je souhaiterai en première ligne pour automatiser le démarrage sur Grub et d'ailleurs s'il était possible, supprimer les autres choix de ce menu, qui sont obsolètes.
Encore merci pour votre support et votre patience
