Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda5,
using the following options:  sda2/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 24.04.2 LTS 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)

Re : Dual Boot does not work with Windows 10 on my PC

Bonjour
C'est un ordinateur HP donc, il faut utiliser les touches du bios d'accès au boot (F11? F9? F12?)
et dire de booter sur /efi/ubuntu/shimx64.efi
