Dual-booting Windows 11 and Android TV on a single device can be a bit complicated, as it requires modifying the device's bootloader and partitioning the storage appropriately. However, please note that modifying your device's bootloader and partitioning can be risky and may void your warranty. Make sure to back up all your important data before attempting this process and proceed at your own risk. 

Here's a general overview of the steps involved:

Check device compatibility:

Ensure that your device supports both Windows 11 and Android TV. Windows 11 has certain hardware requirements, so make sure your device meets them. Additionally, Android TV may have specific compatibility requirements depending on your device.

Create a backup:

Before proceeding, create a complete backup of your device, including all your files, documents, and any other important data. This will ensure that you have a copy of everything in case something goes wrong during the process.

Partition your hard drive:

To dual-boot Windows 11 and Android TV, you need to partition your hard drive to create

separate partitions for each operating system. You can use disk partitioning tools like EaseUS Partition Master or the built-in partitioning tools in Windows 11 to create the necessary partitions.

Install Windows 11:

Install Windows 11 on one of the newly created partitions. You can either use a Windows 11 installation disk or create a bootable USB drive with the Windows 11 installation files. Follow the on-screen instructions to install Windows 11 on the desired partition.

Install Android TV:

Once Windows 11 is installed, you need to install Android TV on the second partition. The exact method for installing Android TV will depend on your device. You may need to find a custom ROM or a specific installation method designed for your device. It's important to research and find the appropriate resources and guides specific to your device model.

Modify the bootloader:

After both Windows 11 and Android TV are installed, you need to modify the bootloader to enable dual-boot functionality. This step can vary depending on your device and the specific bootloader used. You may need to research and find guides or tools specific to your device to modify the bootloader accordingly.

Select the operating system:

Once the bootloader is modified, you should be able to select the operating system you want to boot into each time you start your device. You'll typically see a boot menu during startup, allowing you to choose between Windows 11 and Android TV.

How to install windows 11 operating system

To install Windows 11 operating system, you can follow these general steps:

System Requirements: 

Make sure your computer meets the minimum system requirements for Windows 11. These requirements include a compatible processor, at least 4 GB of RAM, 64 GB of storage, DirectX 12 compatible graphics with a WDDM 2.0 driver, and a display that supports at least 720p resolution.

Backup your data: 

Before proceeding with the installation, it's always a good idea to back up your important files and data to prevent any potential loss during the installation process.

Obtain Windows 11 installation media: 

You can download the Windows 11 ISO file from the official Microsoft website. Ensure that you download the appropriate version (32-bit or 64-bit) based on your computer's hardware.

Create a bootable USB drive: 

Use a tool like Rufus or the Windows USB/DVD Download Tool to create a bootable USB drive with the Windows 11 installation files. Insert a blank USB drive, select the ISO file you downloaded, and follow the instructions to create the bootable USB drive.

Set up BIOS/UEFI settings: 

Restart your computer and access the BIOS or UEFI settings by pressing the designated key during the startup process (common keys include F2, F10, or Delete). Once in the BIOS/UEFI settings, make sure the boot order is set to prioritize booting from the USB drive.

Install Windows 11: 

Save the BIOS/UEFI settings and restart your computer with the bootable USB drive inserted. The Windows 11 installation process will begin. Follow the on-screen prompts to select your language, keyboard layout, and other preferences. When prompted, choose the installation type (custom or upgrade) and select the appropriate disk partition to install Windows 11. If necessary, you can create new partitions or modify existing ones during the installation process.

Configure Windows 11: 

After the installation completes, you will be guided through the initial setup process, including signing in with a Microsoft account, setting up privacy settings, and customizing your preferences.

Install drivers and software: 

Once Windows 11 is installed, you may need to install drivers for your hardware components, such as graphics cards, sound cards, or network adapters. Visit the manufacturer's website for your specific hardware components to download and install the latest drivers. Additionally, install any desired software applications.

Windows updates: 

After the installation is complete, make sure to check for and install any available Windows updates to ensure your system is up to date and secure.

How to install android tv operating system with dual boot option

Installing Android TV as a dual-boot option alongside another operating system, such as Windows 11, can be a complex process and may require specific modifications depending on your device. 

Here's a general outline of the steps involved:

Check device compatibility: 

Ensure that your device is compatible with Android TV. Some devices have official Android TV support, while others may require custom ROMs or modifications. Research whether Android TV is available for your specific device model and check for any compatibility requirements.

Backup your data: 

Before proceeding with any modifications, back up all your important data to avoid potential data loss during the installation process.

Unlock bootloader: 

Most devices require an unlocked bootloader to install custom operating systems like Android TV. Unlocking the bootloader may vary depending on the device model. It often involves enabling developer options and USB debugging, using tools provided by the device manufacturer, or following specific instructions provided by the developer community for your device.

Research custom ROMs: 

Look for custom ROMs that are specifically designed for your device and support Android TV. Websites like XDA Developers or device-specific forums are good places to search for custom ROMs and installation guides. Find a reliable and compatible custom ROM that suits your needs.

Download the required files: 

Once you have identified a suitable custom ROM, download the necessary files, including the Android TV ROM and any additional files or tools required for installation.

Flash the custom ROM: 

Follow the installation instructions provided by the custom ROM developer or the installation guide specific to your device. The process typically involves booting your device into recovery mode, wiping the existing system, and flashing the Android TV ROM from the downloaded files. This process will overwrite your current operating system, so ensure you have the necessary files and backups.

Configure dual-boot functionality: 

Depending on your device, you may need to modify the bootloader or install a custom bootloader that supports dual booting. Research the specific requirements and instructions for your device to enable dual-boot functionality. This step often involves partitioning your device's storage appropriately and configuring the bootloader to recognize both operating systems.

Select the operating system: 

Once the installation and configuration are complete, you should be able to select the operating system you want to boot into each time you start your device. The bootloader or boot menu will typically provide options to choose between Android TV and the other installed operating system (e.g., Windows 11).
