It works really well since EFI.Win/Linux dual boot really works those days? I always read horror storys about that. Nice to see that it even works onto such a special device, even if I do not need Linux personaly on a X86 handheld.
All OSes write their boot information as files in that partition and do not touch the others files.
But if you don't need Linux on it, it will work even better without dual boot ;-)
