@george1421 There is no error message, “>>Start PXE over IPv4” message and after a minute booting to HDD. Fog Server and PXE boot client are in the same VLAN but DHCP server is in a different VLAN. Tried with snponly.efi, intel.efi and pexe.efi but no luck. There is no issue with the DHCP IP release if I boot the PC in Windows, and there is no issue in booting with undionly.exe on the same PC. I am new to Wireshark, please guide me to run the capture filter. Thanks.
