...INSTALL the systems to HARD DRIVE
Say for example that you have a laptop with Windows 10 installed as the only operating system. If you just create one extra partition of about 5 GB you can install Nougat/Marshmallow/Lollipop on this extra partition and then “dual-boot”. I.e. decide whether you want to start Windows or Android-x86 Marshmallow/Lollipop. Grub will be installed as boot handler/loader during the installation of Android Marshmallow/Lollipop. NOTE: The installation will take only about one minute. And the installation to hard drive is so simple that a 10 year old child can do it.
