And execute set up but at booting process only menu is coming with four option like try Ubuntu without installing etc.
But not getting forward in any option
How will we install Ubuntu?

I hope you have solved your issue.
It seems you have your usb drive still attached to the system. The system is taking the live ubuntu from usb drive instead of installed one.
