|If it won't boot off a USB CD drive, how do you expect it to boot off a USB flash drive?|
And why do you keep hammering us about this ISO file? You can't boot off an ISO unless you make it bootable using special software such as MagicISO. I don't know where you got the ISO from but you should just convert/burn it to a CD. It's uselss the way it is. Use ImgBurn like I've recommended several times now. Once you've created the CD, you can either use it as-is, or copy the files off it to create a bootable USB flash drive. Once again, I attached a link in your other thread that details what you need to do to prepare the flash drive.
