[résolu] Récupération de grub par KDE neon
Bonjour,
Je suis en multi-boot avec Kubuntu 21.10 et KDE Neon à jour.
Au quotidien, j'utilise Kubuntu
J'aimerais que le grub utilisé par le PC soit celui installé par KDE neon.
Suite à la lecture de cette page Comment restaurer GRUB j'ai essayé ceci sous KDE neon :
sudo os-prober
sudo update-grub
sudo grub-install /dev/sdamais au démarrage du PC c'est toujours le grub de Kubuntu qui apparaît.
Quelle est le code à utiliser pour choisir un GRUB?

Es-tu bien au clair sur ce que tu veux et as-tu bien fait tes manip à partir de KDE néon ?

Re : [résolu] Récupération de grub par KDE neon
Bonjour,
A priori, la dernière commande
sudo grub-install /dev/sdaaurait du installer la version "KDE Neon" comme version de démarrage en écrasant la version "kubuntu". Comment est organisé ton partitionnement ? Un boot-info pourrait être utile

Comme je le disais : tout dépend de qui l'a exécuté... Et puis j'ai 2 questions pièges à poser :
- comment déterminer de quel OS provient le GRUB autrement que par la première ligne de boot présentée ?
- pourquoi vouloir un GRUB plutôt que l'autre au delà du choix de la première ligne de boot ?

Re : [résolu] Récupération de grub par KDE neon
Sur mon fixe, j'ai 7 versions de linux réparties sur 3 HD; chaque version dispose de son propre grub (installé soit sur le HD correspondant, soit sur la partition "/" de l"OS.
Le démarrage se fait sur le disque choisi dans le bios à cet effet (pour moi, c"est le grub "Ubuntu") et je peux choisir le grub de démarrage soit en changeant de support de démarrage (touche F12 au boot; option courante mais pas universelle), et pour les grub installés ailleurs qu"en MBR j'utilise les options que j'ai créées dans le fichier xx-custom de /etc/grub.d.
Evidemment, tout ceci exige d'être en boot legacy et j'appréhende le jour où je serais contraint de passer à GPT/UEFI.
Tout ceci pour dire que l’utilisation conjointe de plusieurs versions de grub est parfaitement possible, mais demande de l'organisation.
Du coup, pour le cas qui nous occupe ici, il y a lieu de savoir où se trouve(nt) le(s) fichier(s) grub utilisé(s), car je présume que le boot se fait en UEFI (à confirmer) Il me semble que dans ce cas, il peut y avoir plusieurs fichiers "grub" dans la partition de boot, mais je ne connais pas la manip pour les trier.

En fait non et même bien au contraire : c'est bien plus facile à gérer en uefi... Celà dit je fais allusion à une installation monodisque qui sera présenté par l'uefi de façon clairement nommé presque comme l'est ton multiboot actuel... Dans le cas d'installations multidisque en uefi à mon avis pour être sûr que chaque disque dur fonctionnent de façon autonome il faut qu'il y en ait qu'un seul de branché à la fois au moment de l'installation... Sinon tout risque de se coller dans une unique partition uefi...

Re : [résolu] Récupération de grub par KDE neon
Pour sélectionner un logiciel de démarrage en uefi, j'ai trouvé ça :
Il existe plusieurs façons de procéder, notamment:
L'utilitaire de configuration EFI - La plupart des EFI fournissent des utilitaires de configuration auxquels vous pouvez accéder en appuyant sur une touche spéciale au démarrage (Esc, Del ou une touche de fonction, généralement; mais quelle clé il s'agit d'un système à l'autre). Celles-ci fournissent souvent, mais pas toujours, un moyen d'ajuster l'ordre de démarrage. Si votre micrologiciel propose une telle option, vous devriez pouvoir l'utiliser pour déplacer GRUB en position supérieure. (GRUB est susceptible d'être appelé ubuntu, étant donné que vous l'avez installé à partir de cette distribution.)
Un shell EFI - Vous pouvez utiliser la bcfgcommande dans un shell EFI version 2, comme décrit sur le wiki Arch Linux. Si votre système n'est pas déjà configuré avec un shell facile d'accès, cette approche est probablement plus difficile à utiliser que les autres, mais elle est indépendante du système d'exploitation.
EasyUEFI - Le programme Windows EasyUEFI tiers est probablement le moyen le plus simple de faire ce que vous voulez. Vous pouvez cliquer sur l' ubuntuentrée dans la liste d'EasyUEFI et la déplacer vers le haut.
bcdedit- La bcdeditcommande Windows peut modifier l'ordre de démarrage basé sur NVRAM. Plus précisément, ouvrir une fenêtre d'invite de commandes administrateur et taper bcdedit /set "{bootmgr}" path \EFI\ubuntu\shimx64.efi(éventuellement suivi par bcdedit /set "{bootmgr}" description "ubuntu"pour garder la description sensible) devrait faire l'affaire.
efibootmgr- Cet outil Linux peut ajuster l'ordre de démarrage. Commencez par taper sudo efibootmgrseul pour voir les options. Notez le numéro ( Boot####) associé à l' ubuntuentrée et l'ordre de démarrage actuel (sur la BootOrderligne). Vous pouvez ensuite entrer un nouvel ordre de démarrage avec l' ubuntuentrée en haut en utilisant l' -ooption. Par exemple, si l'ordre de démarrage actuel est 0000 0003 ubuntu0007 0004 et 0007, vous devez taper sudo efibootmgr -o 0007,0000,0003,0004pour ajuster l'ordre de démarrage.
refind-mkdefault- Ce script est livré avec rEFInd, et c'est un moyen d'automatiser la procédure précédente. Si vous n'utilisez pas rEFInd, vous devez télécharger le script ici et le rendre exécutable ( chmod a+x refind-mkdefault). Vous devez ensuite l'exécuter en tant que sudo ./refind-mkdefault -L ubuntuou sudo ./refind-mkdefault -L shimx64pour faire de GRUB l'entrée de démarrage par défaut.
Il existe des problèmes potentiels et des complications avec l'une de ces options. Le facteur de complication le plus probable est s'il existe des ubuntuentrées de démarrage anciennes ou alternatives . Il est important que vous déplaciez la bonne à la position supérieure dans l'ordre de démarrage; si vous déplacez le mauvais, vous vous retrouverez avec aucun changement de comportement ou quelque chose de non fonctionnel, ce qui rendrait le démarrage plus difficile. Si vous utilisez efibootmgr, la BootCurrentligne peut vous aider à dire quelle option vous devez définir par défaut.
Il existe d'autres façons de le faire qui sont exagérées. La réinstallation de GRUB (via Boot Repair ou grub-install) devrait faire l'affaire, par exemple. Cependant, ces approches risquent d'endommager une configuration GRUB connue.
Notez également que certains EFI sont bogués et que d'autres problèmes peuvent rendre difficile le démarrage fiable de GRUB. Vous voudrez peut-être consulter ces questions et réponses sur AskUbuntu si vous rencontrez de tels problèmes:
efibootmanager -o les modifications sont perdues au redémarrage

Re : [résolu] Récupération de grub par KDE neon
On doit y voir, entre autres, le chapitre 4.1 (mais tout est bon à lire). On peut alors comprendre que GRUB, en EFI, est installé dans deux endroits bien distincts (tout comme en LEGACY d’ailleurs). Une première partie dans la partition esp (dans le MBR en LEGACY mais EFI à l’avantage de pouvoir faire cohabiter plusieurs fichiers d’amorçage) dans un répertoire spécifique au système installé. Et la deuxième partie dans la partition racine du système installé (tout comme en LEGACY).
Dans le cas qui nous intéresse, on peut voir :
Boot0001* neon HD(2,GPT,76740ca4-4b7a-41ae-afa8-5c0e96c9d6c7,0xfa000,0x32000)/File(\EFI\neon\shimx64.efi)
Ce fichier d’amorçage shimx64.efi va lire le fichier grub.cfg qui se trouve à ses côtés. Et ce fichier lui dit d’aller lire l’autre grub.cfg qui se trouve dans la partition du système installé (neon en l’occurrence).
Je maintiens donc qu’il s’agit du GRUB de neon et pas un autre.

Tu as raison sur un point... Mais un update-grub de kubuntu ne fera pas tout voler en éclat ? Nb : jouer sur la priorité de l'uefi est différent de jouer sur la priorité des différents GRUB

Un update-grub dans Kubuntu ne modifie que le grub.cfg de sa partition.

Eh bien non. car la priorité de l’UEFI lance un fichier .efi bien précis qui lui-même lance un GRUB bien précis.

Non mais ça là dessus on est bien d'accord... Mais donc les questions à se poser sont dans l'ordre :
- est-ce que l'uefi pointe sur le bon GRUB
- est-ce que les GRUB sont bien configurés proprement
Et perso c'est bien sur ce second point que j'ai des doutes... Mais normalement en regardant le Bootinfo dans son ensemble on devrait être au clair

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)Kubuntu user qui aimerait passer définitivement au bureau standard.
