Another distro (UTUTO XS) Live USB problems.

I want to create a Live USB for Ututo XS (for testing and then for installing). But I cannot create it.
Problems:
0. usb-creator-bothguis — not working with Ututo's iso.
1. dd if=file of=usb — UDF FS and not booting
2. Copy files on boot partition — frozen on boot.
This iso is intel64 and it's working on QEMU. I though my CPU is i686 but it's intel64.
