Installing/booting Ubuntu (any version) from usb on Acer One 10 S1002

I have an Acer One 10 S1002 (4in1), wich comes with W10 preinstalled. For usual, booting ubuntu doesn´t require high complications, but in this case, someone thought that: -> using a 32 uefi in 64 proccesor -> restrict at max the BIOS -> Set max security on boot was a good idea.

I think I thried everything I can get from google (rufus+ub15.04x64+gpt), but nothing seems do anything to make the USB key recognizable for the BIOS boot menu.

Any idea?
