@devsamit Alright. We can help you sort this out. First, I congratulate you on trying to setup FOG yourself, and I congratulate you again about seeking help here. That said, I would recommend you install (not upgrade) Ubuntu 16.04 on the laptop, and then install FOG 1.3.0 Release Candidate onto it. There are many reasons for this that I’d be glad to explain, but it’s quite a long list of reasons.So, install Ubuntu 16.04 (not upgrade). Then install FOG 1.3.0 RC via these instructions: https://wiki.fogproject.org/wiki/index.php?title=Upgrade_to_trunk You can adjust your existing DHCP server to give DHCP option 066 and 067. 066 is the FOG Server’s IP address. 067 should be undionly.kkpxe There is documentation on this process here: https://wiki.fogproject.org/wiki/index.php?title=Modifying_existing_DHCP_server_to_work_with_FOG
These steps if done without delay might take an hour.
