F14 USB install problem - unknown keyword in syslinux.cfg
I made a F14 USB installer with liveusb-creator. When booting from it I get "unknown keyword in syslinux.cfg", and then it hangs, with no more messages. There is no information about which keyword is unknown! Searching the forums, I see that problems like this have been around since 2005, but none of the solutions given seem relevant to F14. How do I debug this?
