This is the screen that grants me when i boot UEFI on my Kali Linux system (i ran "ls" for convenience). The only exception is my portable PC, the one i used to get Kali on my USB stick.
There seem to be a boot manager implemented in my computer, it's the only way i can use my Linux. I'm seeking a way to make grub on my USB (by using the third option) boot directly on Kali, and i tried everything, if not voodoo dolls. This forum is my last chance, I just need a way to boot in the USB from the USB.
I also ran "ls" on my other computer to give most information possible.
