3. Create a folder
/EFI/Boot in your USB (You now have some data of Kali Linux in your USB already).
See Picture.
4. Download
bootx64.efi,
MokManager.efi (don't know if this is needed, but I just do it anyway), and
grubx64.efi from here:
ftp://mirrors.kernel.org/fedora/rele...4/os/EFI/BOOT/
then put them into
/EFI/Boot folder you created in step 3.
5. Create a file named
grub.cfg in
/EFI/Boot in your USB with the following contents:
Note: You can download the file here too:
grub.txt. But make sure you put it into
/EFI/Boot folder in your USB along with the 3 files in
step 4 and change the name to
grub.cfg.
See Picture.
