Bonjour,
Un portable acheté d'occasion, avec W$. J'ai installé xubuntu à côté, histoire d'avoir les deux OS, en cas de revente.
L'installation s'est bien passée, et à chaque mise en marche, j'avais le menu qui me permettait de choisir l'OS, avec xubuntu en priorité (donc "Entrée" suffisait).
Et un jour, plus rien d'affiché, et au bout d'un "certain temps", assez long du reste, xubuntu se lance, et fonctionne d'ailleurs normalement.
J'aimerais bien retrouver la configuration d'avant, ou, mieux, la possibilité de la faire apparaître au besoin, par exemple, comme en tapant F11, comme sur ma machine de bureau.
J'ai lancé boot-info, mais je n'ai pas la formation pour interpréter, encore moins pour savoir quelle modification apporter, et où l'apporter !
Merci de votre aide !

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda7,
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 - Ubuntu 20.04.1 LTS 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)
Edit : Solution trouvée, à force de tatônnements : Il faut intervenir dans le BIOS.
