Hi,
The best way to do it would be to download a free tool called RUFUS... Just do a search... It does not install... just runs...
Insert your flash drive before launching RUFUS... Browse to the downloaded ISO, and use all Default options...
Use all default options with Parted Magic as well...
Here is an image of the completed burn... Mine will be slightly different s far as some of the names, but this is what your burn options should look like...
