Hello i am running Ubuntu 14.04 and wish to create a Windows 7 Install USB and yes i do have a product key to verify. i have used UNetbootin and the drive is formatted to ntfs and have tried fat32. it goes to a gui where the only selection option is default and hitting any key resets the automatic boot 10-0 to reset and when it reaches 0 it restarts. i tried installing through the terminal and throws an error of missing operating system. any possible way would help.
