Assuming that you are in windows trying to make a bootable usb stick of Ubuntu.
Download this tool, which will help you make your usb stick a bootable one by extracting the files on the iso to the usb memory stick.
After extracting, boot up with the usb. Prior to installation, if you haven't installed Linux OS's before, please read on that.
(How to use this software are given in simple, in the above website itself).
