I was trying to install Ubuntu 14.04 64 bit on my acer aspire e15. it has intel pentium quad core processor N3540.
Inserted the cd/usb (tried both), boot menu, selected my boot device and then the Ubuntu screen appeared with little dots and was loading forever (I think it froze). Same thing happened when I was using usb.
Tried installing ubuntu 16.04 64 bit, same thing happened.
I've read here that it is possible to install it on my machine.
