The only way that I'm able to use usb-creator is to format the usb-key in FAT32 then:
Code:
sudo usb-creator-gtk --iso=/path/to/iso
Then select Erase Disk button (wait a moment that the disk will be available again), choose the desired extra space and finaly click on Make Startup Disk button
Done!
In this way I'm able to put the distro isos on usb-key since Lucid; tried everything else without luck.
