I had similar problem in the past.
When set up in Windoz, the Flash Key was bootable.
When in Linux, nothing.
My problem was solved by 'cat mbr.bin > /dev/sda'
Simply said, if you write the bootloader (syslinux) to /dev/sda1
in Linux, it doesn't do anything unless you put a generic MBR code
to the MBR area of your device. Because MBR is read and executed
first, and then the MBR code looks for partitions and bootloader in sda1.
Syslinux in windows will write the MBR, but syslinux in Linux won't.
Hope this helps.
