Unetbootin worked fine for me up to 14.10. Bootable USB keys created with unetbootin in 14.10 display "Failed to load COM32 file menu.c32 boot: " when I try too boot these USB keys.
I made two of them ( most recent versions of Parted Magic and Knoppix) and both of them stop and display the error message "Failed to load COM32 file menu.c32" boot: "
When you see this message, hit the "Tab" key and you will see a list of booting options:

I just type unetbootindefault and that starts the booting from the USB key .
It seems that the booting from default is not working, but I do not know why...
Hope this helps
