When I start a deployment task and reboot the target machine, PXE boot will not start for me. It will just load the startup menu after 30 seconds or so. 

I have added options 66 / 67 to our DHCP server (Palo Alto Firewall). 

I am able to capture an image of the target machines but cannot deploy a task. 

Does anyone have any advice? This is a new software for us.
