J'ai donc entrepris de fabriquer une clé bootable pour ma fille, en suivant le [doc]/tutoriel/installation_sur_disque_usb[/doc].
Par habitude, je l'ai fait sur ma machine, La clé bootait sur mon ordi, mais pas sur le sien.
En voulant me remettre au travail, je découvre avec stupéfaction que ma machine affiche au reboot le même message d'erreur que chez ma fille: minimal BASH...
Je me dis alors: et si c'était un virus ou une saleté du genre qui serait passé du laptop de ma fille au mien, par une des deux clés USB qui ont été branchées successivement sur les deux machine? Le problème serait alors de d'ordre logiciel, et on pourrait s'en débarrasser par simple réinstallation du système. Et c'est ce que j'ai tenté. (Par chance, ma fille avait une sauvegarde des données importantes).
L'install s'est déroulée sans aucun accroc. Le nouveau systéme tourne bien depuis une journée déjà.
Je remets le boot-info

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !
=================== User settings
The settings chosen by the user will not act on the boot.

Le disque a fonctionné 1292 h, ça n'est pas énorme.
Mais il a été allumé/éteint beaucoup trop souvent,
Power_Cycle_Count : 10986
Ça donne un durée de session moyenne de 5 min :o
La réinstall sur ma propre machine s'est aussi déroulée sans histoire.
Je suis bien content d'être sorti de la gonfle. Mais des questions restent.
Pensant aux choses inhabituelles qui ont précédé ce double crash, je retiens:
Sur les 2 machines:
-Utilisation de Zoom, qui nous permet de donner nos cours pendant le confinement.
Sur le Macbook Air de ma fille:
-batterie pas fiable du tout
Sur ma propre machine:
- 4-5 gels du système exigeant un reboot par les touches magiques.
- Craquement au boot, qui a disparu après réinstall
- Système "gonflé" à 19 Gio alors que d'habitude, il en fait 7 ou 8.
Je m'en suis rendu compte en réinstallant (j'ai un /home séparé sur cette machine)
Je passe en [résolu].
Mais si jamais tu as une idée d'où le problème est venu, Ça m'intéresse.
