We’re all aware of the changing era, Canonical has its own success in making history by bringing Ubuntu to Android, and its engineers and developers have done it yet again by releasing a dual-boot installer, which will provide an efficient way to dual boot Ubuntu and any Android-based OS.
The Installer is released as a developer preview, which is recommended for developers/users who have knowledge of Android device partitions, as later you may need to flash manually if something goes wrong. A developer preview because it is yet a work-in-progress (you might tackle bugs, major and minor both) which requires testing, observation, and re-working based on the user feedback. The Installer works on the theory of switching via an App, both in Ubuntu and Android, the App itself requires Superuser permissions to operate, so it is highly necessary to have your Android devices already rooted. In case, you haven’t got your device rooted yet, the Dual boot App serves you with an inbuilt option to Install SuperUser App.
Below are the guides to root the supported devices:
- The Installer has been tested completely on Nexus 4, if you’re willing to try it on other devices, be aware of the risks and required knowledge to recover yourself from any situation.
- If you’re Installing Ubuntu and Android 4.4 ROM side-by-side, you will need to follow these steps to make Phone calls functional.
- If anything goes wrong, you can simply Install the custom recovery as only the recovery partition is amended during dual-boot process.
Dual boot installer requires a supported device including Nexus 4, Galaxy Nexus, Nexus 7 and Nexus 10 running on Android version 4.2 with unlocked bootloader and at least 2.7 GB of phone storage. You should also make your PC ready by installing ADB tools.
Since it is a developer preview, it might be unstable as compared to your daily Ubuntu builds. Visit the installation guide and begin your journey with dual booting.
