Hi,

The easier way is to use my new menu test demo, download resource file at:

http://grub4dos.sourceforge.net/menu.zip

Unzip to the boot partition, you should see many files under /menu/ directory.

Then you just need to add this line at the end of grub.cfg:

source /menu/menu_efi.cfg

It'd boot into graphic mode by default, you can use F8 to switch
between text and graphic mode.

Yep, you need that, debian will enable it by default, I don't know
about gentoo thought.
