I did installed 14.04 and its working fine!
But Im facing a new problem!
When I shutdown my system while using Ubuntu 14.04 it sent me back to Grub loader to select the operating system to login.
This cycle continues if I login again Ubuntu but Im successfully shutdown my system if i Select window from the Grub menu and then
select the shutdown option.
do you have any idea how can i properly shutdown my system from Ubuntu?
Again thanks for you suggest!
