Download Preview Version of Intel Android-IA 4.2.2 with Dual Boot Support (Android/Win8) on UEFI and Linux Kernel 3.8

A developer preview version of Android-IA OS has been released recently on (, which includes Android 4.2.2, support for Linux Kernel 3.8, and dual boot support (Android/Win8) on UEFI systems. The new release of Android stack also adds support for signed kernel modules. This is a pre-alpha quality. It is buggy and not highly optimized. You have been warned. Have fun with it if you know what you are doing:-)

 Here are some key features:

    * UEFI Boot (legacy BIOS booting no longer supported)
    * Android 4.2.2
    * Linux 3.8.0 kernel
    * Interactive Installer / Win8 Dual-Boot
    * Signed kernel modules

Starting with this release, Android-IA only supports booting on UEFI mode. To boot the installer, you must turn on UEFI boot through your BIOS menus. After downloading, please refer to the Quick Start for instructions on getting started with Android-IA.

In addition, the installer has been enhanced to support dual boot with Windows 8. We've had success using this on many devices, but if you would like to try this keep the following points in mind:

  • This has only been tested with Windows 8 and only with an EFI installation. We don't support dual booting with Legacy BIOS installations. The Windows 8 that comes installed on the Acer W700 is in EFI mode; there shouldn't be any Windows 8 slates shipping with a Legacy installation.
  • Back up all your data! This is very important! Don't use this with any data you care about!
  • If your device doesn't have any software on it, you should install Windows 8 first. You will need to delete all existing partitions in the Windows installer.
  • The automatic installer has had a policy change; if it detects an EFI installation of Windows 8, it will not disturb it. Instead it will try to use unpartitioned space on the disk or replace an existing Android installation. Once you have dual boot set up, the automatic installer is suitable for updating the current installation if you don't want to use Fastboot or OTA updates.
  • If the interactive installer detects a Windows 8 installation, it will ask you if you want to dual boot. If you say no, the entire disk will be erased and replaced with Android-IA. If the installer doesn't detect Windows 8, it was probably installed in Legacy mode.
  • The interactive installer will let you resize Windows 8's data partition to make room. This uses the open source ntfsresize utility. After resizing the disk, the next time you boot into Windows it will go through a repair cycle; this is normal.
  • The command line interface to the installer is pretty crude at the moment and will be undergoing some improvements in the weeks to come.

The source code for this release is available by syncing the manifest branch android-4.2.2_r1-ia0. More details on working with repo, manifests, and source code are available on the Developers page.
