I want to apologize because the issue was because of an electrical problem, the hard disk is a solid state disk working into a mobile robot, and apparently the sata connector wasn't in the right position and at some point of the installation began to fail. I tried the same usb pen drive in another machine and the partition was made properly, later I tried again in the original machine and after that I recheck the hardware and discovered the issue with the sata connector. I still face another problem but, following your directions, I will raise another thread with that issue.
I'm sorry because of the issue, Adrian
