Why i could not install centos7 with gnome desktop
 

I seleced the server with gui option when i installed the centos 7 on my vmware VM
But after installation i could not start the Server with gui? Why is that?

server and gui are two different things

what desktop enviroment did you install ?
Gnome is the default .

and dose the VM meet the min. system requirements for a gui ?

I have install GNOME environment.

so to repeat
dose the vm meat the minimal requirements for gnome3 desktop ?
is your 3d card pasted through ?
is there enough ram set ?

and please expand on
is it booting into text only
or
NOT booting
