I have the same issue.
Mark,
did you ever find a way to solve this problem?
thx in advance!
did you create your Preboot with the Boot Disk Creator?
if you click new to create a new Preboot and than add Preboot
is there any Preboot installed?
can you send a screenshot?
Also having this exact same problem...
Hi Craig,
Have you gone through the tips that were provided in this thread? If you click on the Status tab, what is the status of the PXE server that you are experiencing this issue from (i.e. offline, updating, etc.).
I had the same issue last week, I had to stop pxe services, made a copy of pxemanager.ini and pxe.ini (do the same for other pxe servers if affected) edit both these files to remove the pxe option numbers that were not displaying on the boot menu. restarted pxe services and recreated the bad options and all was good.
