Let's take note of this file name:

vmlinuz-huge-4.4.14

For convenience, I'll repeat the file name we took note above:

vmlinuz-huge-4.4.14

and we should compare it with the one being used in the syslinux.cfg:

vmlinuz--huge-4.4.14

Do you note the extra dash symbol "-"?

is just a simple typo issue?
