Thanks so much for your feedback. I've done that already and disabled Hyper-V in 2 ways (GUI and power shell )in my previous researches. I think that is the real issue, that Hyper-v is not getting disabled as it should . Will research little bit more in regards of that feature and will keep you posted

Since these VMs are preatty important for my dayli basis , I thoutht about a workaround , so I install ESXI on the VM workstation  and it got installed  fine however when I try to build the same VM (FMC 6.4.0) I get an error not allowing it to boot . This time I receive the following error . 

"Failed to power on virtual machine FMC-6.4. This host does not support Intel VT-x. " 

Virtualize Intel VT-x /EPT or AMD-v/RVI box is not checked on VM created to host ESXI ,which suposes to be the issue . So I'm not sure if this could be also related . This option is also disabled for VM created to host FMC .
