Running Windows on the POCO X3 Pro

Dualbooting Android and Windows seamlessly

Prerequisites

A rooted vayu with Windows already installed
Secure Boot UEFI image
M3K WoA Helper
StA Installer

Setting up the dualboot app

This guide assumes you are rooted, if you aren't, please do this first

Setup - Android

Download and install the M3K WoA Helper app, then open it and grant it root access.
Download the Secure Boot UEFI image for your panel and place it inside the folder named UEFI in your internal storage.
Press the MOUNT WINDOWS button, then download and move StA_Installer_vayu.exe to the newly created Windows folder in your internal storage.
Return to the M3K WoA Helper app and press QUICKBOOT TO WINDOWS.

Note

The first Windows boot can take up to 10 minutes, don't worry and just wait

Setup - Windows

Navigate to C:\StA_Installer_vayu.exe and run it. If it doesn't work, make sure that any antivirus software is off, as it will probably not let the app run

Booting to Android

Run the new shortcut on your desktop (you can also pin it to your start menu / taskbar for ease of access)

Booting to Windows

Press QUICKBOOT TO WINDOWS inside the app, or use the newly created toggle in your quick settings panel

Finished!
