===== Uefi problem =====


# MOK problem
I solved this problem.

Create a Live USB/CD of Ubuntu 17.10.
Boot this USB/CD in UEFI mode (the problem doesn't happen with this version).
Open terminal and use this command: sudo mokutil --reset.
Try to boot with the system you want to install.
If you get this another error "Failed to open \EFI\BOOT\mmx64.efi", change the file name of "grubx64.efi" to "mmx64.efi" (located on /efi/boot on USB/CD).
Boot again and you will see no errors (I hope so).
