@ram There are so many questions because your post lacks details.

1. Is this a new FOG install?
2. What did you configure in your main dhcp server for options 66 and 67?
3. Is your pxe booting client a bios or uefi computer?
4. If you select the boot manager on the target computer (typ F10 or F12) can you select pxe boot? If yes what error message do you get?
