Troubles booting Kali Linux

[_defalt]

But what is the problem? You have mentioned every other thing except the problem itself. Kali fully supports UEFI.

First, thanks for responding this fast ! Well, when I want to boot on my usb drive, it simply doesn't work. In my other tries, it actually either wrote the error : \g21dr.mbr , or just stick to a black screen with a "white blinking thing that wasn't blinking ) on the top left corner.
Currently, when I go to my BIOS, when I go to the section "Boot Device" I got 2 "Windows Boot Manager" instead of one + the usb.
Hope that you understood what I've said .
