You can use search command to locate the root device. Something like this:

search --set /vmlinuz
linux /vmlinuz ...
initrd /initrd.img

If you use my repo, you can enable graphic mode for EFI, it even
allows you to set a background image. Add these lines in grub.cfg:

set gfxmode="0x0"
loadfont /unifont.pf2
background_image /splash.png

You need to include these modules when generating grub.efi: video
efi_fb gfxterm font png jpeg

unifont.pf2 is the font file, you can generate it using grub-mkfont,
or just download it here:
