Comment 34 for bug 859539

But it seems that it not writing anything I'm still not able to boot from it.

I'm suspecting a problem in grub in ubuntu 13.10 iso. I have downloaded it several times. The first time I have tried I have been able to create a bootable usb and then I tried to install saucy on another usb key as standard installation but grub was not showing up at the startup.
