There are some that you placed ie.. grub.cfg that are blank yet they exist and are in the appropriate boot folders and some that you placed that are not blank, would this information be helpful to you and would the resulting grub.cfg's original and yours as comparisons be useful to you?

I know my setup is rather complex, but that always helps in catching things that you would not otherwise encounter in basic scenario's.

Please let me know.

I am going to reboot now, just to check things out.
