What happens when you try to boot? Can you see the grub2 menu screen? If you can see the grub2 menu screen you should try using the grub2 command shell (type "c" to enter the command shell) which will allow you to experiment with all of the grub commands that you compiled into the grub2 package. If you can get to the grub shell prompt you can hit TAB to see a list of available grub commands. The important point is this: any grub command that works from the grub shell prompt can be typed *verbatim* into a grub2 'menuitem' stanza. The first time I used grub2-mkconfig I noticed that it generates config files that strike me as a bit hysterical (excuse the sexist adjective).
