I plug in my usb and turn my computer and then the copy rights come on the screen. It then says it cannot find the configuration file and I cannot do anything from there on. It is important to note I did use the universal usb thing and this appeared after I sued that and tried to boot the usb. Any help would be appreciated, thanks.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Try first plugging your USB into another computer and rename the folder "isolinux" to "syslinux" and the files "isolinux.bin" and "isolinux.cfg" in that folder to "syslinux.bin" and "syslinux.cfg" respectively. Then try booting with the USB again.
If that does not work, you will have to reformat your USB to FAT. You can do that using a tool like GParted ("sudo apt-get install gparted" in terminal). After that make the USB drive again and it should be fine.
