Bonsoir,

Cela fait plus d'une semaine que je tente d'installer Ubuntu en dual-boot sur mon petit pc. Je l'ai déjà fait sur d'autres pc mais cette-fois... Ça bloque !

J'ai réservé une partition de 20Go et démarré l'installation (minimale) de la toute dernière version d'Ubuntu depuis une clé bootable très fraîchement faite.
Lors de l'installation, malgré plusieurs tentatives, l'étape de grub-install échoue avec le message suivant :
« L'exécution de "grub-install /dev /sda" a échoué. Cette erreur est fatale. »

Voici le rapport donné par un boot-info depuis la session live de la clé : ... (Voir réponse)
Lorsque je démarre mon pc, comme depuis la première tentative d'installation d'Ubuntu, je tombe sur un grub/terminal de commandes, avec en titre : « GNU GRUB version 2.04 » et pour description : « Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. ». Je peux entrer des commandes (avec devant « grub> _ » ...). Je ne connas pas du tout cela mais j'aurais voulu essayer de faire "load_env" suivi du nom associé à Ubuntu (avec tab) mais malheureusement lorsque je veux taper un underscore _, il s'affiche un 8...

Comment donc réussir l'installation du grub (le vrai, celui dont j'ai l'habitude) ?
Merci d'avance.
Cordialement

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda5,
using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file

Blockers in case of suggested repair: __________________________________________

/target detected. Please close the Ubuntu installer, then retry.

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (sda1/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)
