Unmount sdc1 from /media/clement/UBUNTU 20_0/ to avoid special characters (& or \ or space) incompatibilities
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda3,
using the following options: sda2/boot/efi,

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)
Ton installation est remarquablement réussie (*). Je pense que tu as sélectionné "Installer Ubuntu à côté de Windows" à l'étape "Type d'installation" comme je te l'avais conseillé. Peux-tu le confirmer ?
(*) dans l'état actuel, si tu déconnectes le disque Windows ou que ce disque Windows tombe en panne, tu peux toujours démarrer ton Ubuntu parce que ses éléments de démarrage se trouvent dans la partition EFI sda2. Tu as la chance d'avoir une installation Ubuntu réellement indépendante de Windows.
