I solved my problem by using liveusb-creator for Windows. It's work great. But it's not a unix way. 
I just want to try and to install fedora, because of this I don't have it on my machine and I can't use commands like this: 
yum install livecd-tools

Did you read and follow these instructions?

Also, note:  there is a bug with unetbootin.  It won't work.

Have you done a Google or Yahoo search for solutions to your problems?
