Modifier Grub (Résolu]

Bonjour à tous !
Mon problème de choix multiples de Win 10 ayant été résolu, je voudrais maintenant modifier l'O.S. par défaut.
Pour ce faire, avec Boot Repair, j'ai tenté de mettre le drapeau dans Sda (partition d'Ubuntu 22.04) et de choisir l'O.S. par défaut Ubuntu 22.04.
Boot repair semble content de lui, mais au redémarrage, rien n'a changé : Boot sur Ubuntu 20.04 qui est sur Sdb.
J"ai vu une phrase dans le boot info qui indique qu'il n'y aurait pas assez de place quelque_part.....
Comme je suis encore un peu béotien en ce domaine, existe t-il  un tuto, ou un document explicitant Boot Repair ?
Pouvez vous me conseiller ? Je vous indique le Boot info; http://paste.ubuntu.com/p/93JZByGbTx/
Merci d'avance.

Re : Modifier Grub (Résolu]

Bonjour,
Ton lien vers le présumé bootinfo ne fonctionne pas, pastebin dit qu'il n'y a rien de chargé...
Une question : Es-tu en mode UEFI (avec un fichier /boot/*.efi) ou en mode MBR ?
Parce-que dans le cas du mode UEFI, le système ne cherche pas à démarrer sur le MBR de /dev/sda, mais avec les informations enregistrées dans le fichier .efi. Ce qui expliquerait que rien n'ait changé malgré ta modification via bootrepair.
Je pense qu'il doit y avoir d'autres moyens de régler le grub sans recourir à bootrepair...

Plus de 50 ans d'informatique, ça en fait des lignes de commandes en console, mais on n'avait pas le choix...
Excellente raison pour, aujourd'hui qu'on le peut, utiliser au maximum les INTERFACES GRAPHIQUES !
Important : Une fois le problème solutionné, pensez à clore votre sujet en ajoutant [Résolu] devant le titre du 1er message, et un bref récapitulatif de la solution à la fin de celui-ci. Merci.

Voici un boot info qui fonctionne: https://pastebin.ubuntu.com/p/dmQWvQXwmx/
Merci
Pour info: moi aussi j'ai débuté en 1981 avec le Basic du ZX 81 de Sinclair. Toute une époque !

Re : Modifier Grub (Résolu]

Bah non ! Voilà tout ce qu'on obtient en cliquant sur ton lien :

Et donc, quel est ton mode de boot, UEFI ou MBR ?

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub2 of
sdb5 into the MBR of sdb.
Grub-efi would not be selected by default because no ESP detected.
Additional repair would be performed: unhide-bootmenu-10s

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your BIOS boot on sdb (ATA ST3200822AS) disk!

Re : Modifier Grub (Résolu]

Bonjour,

existe t-il  un tuto, ou un document explicitant Boot Repair ?

Il y a la page de doc boot-repair et notamment le §3.2 pour ce qui te concerne, avec cette image (OS par défaut au démarrage et Placer GRUB dans tous les disques).

Bah non ! Voilà tout ce qu'on obtient en cliquant sur ton lien :

Bah y a qu’à se loguer.

Re : Modifier Grub (Résolu]

O.K. Très bien Grub Customiser....
Je l'ai sous Ubuntu 20.04 mais il ne se charge pas sous Ubuntu 22.04.....
Je ne sais pas pourquoi il a été tant mis en doute car (peut être) dangereux, mais pas si on fait attention, je pense.
Bon c'est réglé , j'ai le Grub que je voulais.
Merci
