Chainloading from Grub2

[jakub-xen]

Hi
I'm trying to chainload from grub but when I do, it doesn't try to load my local menu and just goes and downloads the one from the internet.

Is there something I need to add to make it try to read the local menu? If I use netboot.xyz.efi directly then it works with the local menu.

My entry in grub is very simple:

menuentry 'test' { chainloader /netboot.xyz }

thanks,
Jakub
