I use a x86_64 bit Ubuntu, but whenever I try to do a live boot of any other 64 bit images like the GNOME 3.16 which was released yesterday, it does not work?
Also some times when I try a virtual machine of a 64 bit image, it does not work either.
What is the reason for the same? What is the difference between x86_64 amd64 and 64 bit?
My laptop model is an Hp Pavillion dv4 1506tx. The processor is 2.20 GHz Intel Core 2 Duo Processor T6600
