Donc il faut que l'uefi pointe sur sda8 et non sda9...

freex · Le 28/10/2021, à 08:35

...mais il ne pointe pas sur sda8? :

efibootmgr
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0001,000F,000C,0012,0000
Boot0000  Windows Boot Manager
Boot0001* neon
Boot000C* Hard Drive 
Boot000F* ubuntu
Boot0012* ubuntu

Soit quelle serait la ligne à modifier et dans quel fichier sur la partition EFI ?

FrancisFDZ · Le 28/10/2021, à 09:00

J'ai cru comprendre qu'on pouvait créer plusieurs fichiers de boot dans la partition "efi". Si c'est bien ça, la question devient : comment choisir le fichier de boot (grub ou autre) par défaut

C'est à peu près ce que j'avais compris (je reconnais, je n'ai pas tout compris)

[Edit] La solution serait-elle dans l'article que j'ai déniché en #7 notamment le paragraphe

efibootmgr- Cet outil Linux peut ajuster l'ordre de démarrage. Commencez par taper sudo efibootmgr seul pour voir les options. Notez le numéro ( Boot####) associé à l' entrée ubuntu (soit ici "KDE Plasma") et l'ordre de démarrage actuel (sur la logne BootOrder). Vous pouvez ensuite entrer un nouvel ordre de démarrage avec l' entrée ubuntu (ou "KDE Plasma") en haut en utilisant l' option "-o". Par exemple, si l'ordre de démarrage actuel est 0000 0003 ubuntu0007 0004 et 0007, vous devez taper sudo efibootmgr -o 0007,0000,0003,0004 pour ajuster l'ordre de démarrage.

Ah si... Mais le mieux serait de dégager les autres options de la séquence de boot pour être sûr qu'il ne saute pas la première et la seconde pour en réalité démarrer sur la 3ieme...

Le 0013 n'y est plus car j'avais testé via NEON la commande précédente suggérée et cela n'avait pas fontionné. Je me suis dit que peut-être fallait-il la lancer dans Kubuntu. Sur cet OS, une erreur est apparue (un truc comme "pas d'entré pour 0013"), du coup j'ai enlevé le 0013 de la commande et je l'ai relancée via NEON.

Si je comprends bien, la commande avait renvoyé une erreur et tu avais donc redémarré alors que l’ordre n’avait pas été changé.
Pour être sûr, maintenant que l’ordre est correct, redémarre à nouveau et dis nous ce qu’il en est pour le menu de GRUB.

Toutes ces manipulations n'ont servi à rien, c'est le grub de Kubuntu qui prend le dessus à tout les coups

FrancisFDZ · Le 29/10/2021, à 08:28

As tu testé (voir #28)

efibootmanager -o

Ça devrait renvoyer la liste des différents boot possibles, dans "l'ordre d’entrée en scène"

@FrancisFDZ : tu as un train de retard.

Ceci dit, je ne vois pas d’où peut venir le problème.
Je vais relire le dernier boot-info plus en détail, sait-on jamais.

nany · Le 29/10/2021, à 09:08

Je pense avoir trouvé.

Les deux fichiers ont la même empreinte donc celui de neon est probablement une copie de celui de Kubuntu.

Dans neon, donne le retour de :

sudo grub-install -v

En effet, j'avais loupé ça (nb : ta remarque est un peu vexante pour un ancien cheminot )
Cependant, je n'ai pas vu la réponse à cette demande avant #33 (à moins que ce ne soit la faute de mon ophtalmo )
Et on a bien la réponse claire (en #33) : le boot "neon" a bien été validé et est le boot courant.

Change d’ophtalmo !

La lecture rapide, c'est pas mon truc ! Je vois que je ne maitrise pas la lecture en diagonale !

[Edit] coté ophtalmo, ça risque d'être la cata(racte)strophe !
Et changer d'ophtalmo, vu le délai pour obtenir un RV, pas question ! [/Edit]

Ouais bah tien... J'en profiterai bien pour redemander ce qu'est clairement KDE néon par rapport à kubuntu parce-que j'ai un peu de mal à comprendre pourquoi plusieurs discussions fleurissent au sujet du premier sur notre forum alors qu'on est bien face à une autre distribution dont le support n'est pas officiellement reconnu par canonical et donc ubuntu-fr...

KDE Neon c'est une LTS avec les mises à jours de l'environnement KDE disponibles jusqu'à la LTS suivante.
Plus besoin d'upgrader le système tout les 6 mois pour bénéficier des dernières nouveautés de KDE.

Il n'empêche qu'on parle bien d'une autre distribution ne serait-ce que parce que pour arriver à ça il y a forcément un dépôt potentiellement parasite

Ou alors et c'est pour ça que j'ai profité de l'occasion on parle bien de 2 distributions "identiques"... Celà dit rien n'empêche de faire un dualboot de 2 distributions strictement identique en théorie... Donc bon...

...J'ai écrasé Kubuntu Rescue par NEON
maintenant j'ai un grub NEON mais impossible de le modifier car problème à l'installation de NEON ...et donc cette nouvelle NEON ne se lance pas, j'ai juste le grub
Soit, à l'installation, contrairement à Kubuntu, NEON me demande d'activer le boot flag de la partition EFI FAT32 et de lui atribuer un point de montage /boot/efi ...ce que j'ai fait.
Toujours contrairement à Kubuntu, NEON ne me demande rien à propos de l'emplacement du fichier GRUB, j'ose imaginer qu'il se fait sur /sda

Voici donc le retour de sudo grub-install -v

Merci, pour un prochain message peut-être

Bonjour
Tu en profiteras pour refaire un boot-info après avoir fait la commande de nany si le problème n'est pas résolu
Cela permettra d'avoir le contenu de
- La nvram
- De tous les fichiers de configuration GRUB EFI
- De tous les fichiers de configuration GRUB LEGACY
J'en profite pour rappeler que lorsqu'on dispose d'un ordinateur EFI et qu'on a plusieurs instances à faire booter , on ne sert plus du grub qu'il devient inutile d'installer mais du logiciel REFIND!
sudo apt install refind

Ce n’est pas grave, c’est juste la fin qui est intéressante :

On y voit que les fichiers ont bien été recopiés.

...J'ai écrasé Kubuntu Rescue par NEON
maintenant j'ai un grub NEON mais impossible de le modifier car problème à l'installation de NEON ...et donc cette nouvelle NEON ne se lance pas, j'ai juste le grub

J’ai du mal à bien visualiser la nouvelle situation. Refais un rapport boot-info pour qu’on y voit plus clair.

=============================== StdErr Messages ================================

File descriptor 63 (pipe:[70825]) leaked on lvs invocation. Parent PID 3953: /bin/bash

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda8,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix 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 - KDE neon User - Plasma 25th Anniversary Edition CurrentSession entry (sda2/efi/****/shim****.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\****\shim****.efi (**** will be updated in the final message)

Bonjour
Tu en profiteras pour refaire un boot-info après avoir fait la commande de nany si le problème n'est pas résolu
Cela permettra d'avoir le contenu de
- La nvram
- De tous les fichiers de configuration GRUB EFI
- De tous les fichiers de configuration GRUB LEGACY
J'en profite pour rappeler que lorsqu'on dispose d'un ordinateur EFI et qu'on a plusieurs instances à faire booter , on ne sert plus du grub qu'il devient inutile d'installer mais du logiciel REFIND!
sudo apt install refind

Ok ...mais pourquoi les installations ne prévoient-elles pas de l'installer lorsqu'elles détectent un EFI?
Pour moi, grub ou un autre... à partir du moment où je sais lancer Ubuntu ou Windows...
Je vais jeter un oeil à la doc
