I'm doing something like this but I always get this "Root file system is not defined"... And I have no idea why. Any suggestions?

Thanks for sharing! Pressed documentation is sketchy at best. I've never seen anything on the $bios_boot{ } or method{ biosgrub } directives you used. Can you share where you got that from/what exactly it is doing?
