In my Windows 7 system, I want to install 64-bit Ubuntu 14.04.5 or Ubuntu-Mate 14.04 as a native windows application, but a full length dual-boot system. Earlier it was possible through Wubi Installer and I've used that with 32-bit Linux 14.04.1 LTS. But with my current installation requirement it is not available anymore.
How can make it possible?
Please let me know, if any other information is required.
