Title:
  Impossible to choose a language when booting in UEFI, as Ubiquity
  never opens due to problematic grub config

Bug description:
  When booting Ubuntu or one of its flavors (noticed first with Xubuntu)
  in UEFI mode, ubiquity never opens. The issue this causes is that
  there is never a option to choose a language, so all systems booted in
  UEFI mode are always in English, consequently the language, keyboard
  and timezone are wrong.

  My suggestion is to, instead of having two options (one to try and
  another to install), have one that boots in the ubiquity window,
  asking what the user wants to do and the language the user desires to
  use. Something like:

  menuentry "Start Ubuntu" {
  	set gfxpayload=keep
  	linux	/casper/vmlinuz.efi  file=/cdrom/preseed/ubuntu.seed maybe-ubiquity boot=casper quiet splash ---
  	initrd	/casper/initrd.lz
  }
