If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS 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:

Re : Dual Boot Grub Screen probleme

Déjà si ton pc est un HP t'es p'tete condamner à passer par le boot-menu du bios pour lancer ton Mint.

Cela dit tu sembles l'avoir installé en tout sens : en efi comme en non-efi et je ne sais pas si ça aide.

Re : Dual Boot Grub Screen probleme

Dans les bios acer il existe l'option "select a trusted efi file" qui se trouve dans la section securité.

Avec cette option tu selectionne le shimx64.efi ; cela en gros fera reconnaitre buntu comme os bootable.

Note : il te faudra p'tete creer un compte admin pour obtenir ou pouvoir utiliser la-dite option

Cela dit ton installe buntu n'est pas propre et franchement, si t'as la-dite option, je virerai les partoches linux et installerai en efi proprement.
