Getting "Installation failed" when trying to create gparted live bootable usb

view story

http://ubuntuforums.org – Error says "could not move syslinux files in"/media/3720-2DA2" [Errno 2] No such file or directory. Maybe "tmp/tmpjPxhDn" is not an Ubuntu image?" When I try to boot with it it gets to the "Use at your own risk" warning and then stops at the blinking cursor and does nothing. I'm trying to format a hard drive for a Windows 8 installation and they say trying to use the gparted function in Ubuntu won't work. I have to use the gparted live. Can anyone help with these problems please, it would be very much appreciated! Thanks. (Hardware)
