I downloaded the live KDE version of openSUSE 13.2, verified the checksum, and then put it on an USB drive using the Rufus utility - http://rufus.akeo.ie/.
Then I tried to boot the USB drive, but I got the error “Could not find the kernel image: gfxboot” followed by the boot: prompt, scrolling continuously down the page.
Searching for the error on Google turned up quite a few posts on this forum, obviously relating to earlier versions of the distro, but they mention either Unetbootin or Imagewriter.
I would guess the rufus modifies the ISO for USB booting. That is not need and should not be done with openSUSE. You only need to make a direct binary copy of the iso to the USB device (note NOT a partition, to the device) ie cp name.iso /dev/sdX where sdX is the USB device. This works well I’ve done it several times without problem
