Syslinux - Nov 2015 - PXE automatic reboot after "No bootable device"

Hi all,

I am checking this wiki:

http://www.syslinux.org/wiki/index.php/PXELINUX

I cannot find information about what to do when the machine fails the boot.
The last thing I can see in the console is "No bootable device", and
the
machine keeps stuck there forever.

I would like to know, please, if there is a way to automatically reboot the
machine when this error happens, in order to retry again a good PXE boot.

Many thanks for your assistance.

Best regards,

      Jorge.
