  Recommended for VMware users

To use an ISO file, Linux users could just dump it into a usb drive to create a bootable usb stick like:

dd if=android-x86_64-9.0-rc2.iso of=/dev/sdX

where /dev/sdX is the device name of your usb drive.

Windows users can use the tool Win32 Disk Imager to create a bootable usb stick.

Please read this page about how to install it to the device.

Except the traditional ISO files, we also package android-x86 files into a Linux package rpm. It allows Linux users to easily install the release into an existing Linux device with a standalone ext4 root partition.
