Microsoft Surface Duo comes with a unique dual-screen and offers productivity features. One thing Microsoft has about this phone that makes this phone better than the regular iPhone or Samsung Galaxy is its ability to run Windows 11 (unofficial, of course). Earlier this capability was only available on Surface Duo but now Surface Duo 2 owners can try their luck by swapping out Android 11 for Windows. Below you can check the complete guide of this processor.

Files/Tools Needed:
- A Linux virtual machine with parted installed
- Expert knowledge of what you’re doing (this is even more susceptible to bricks than the duo 1 guide, do not follow for now if you are not comfortable, this is very advanced still)

- Early Boot package: surfaceduo2-bootpkg.img
- Boot package: surfaceduo2-boot.tar
- Windows UEFI: surfaceduo2-uefi.img

- A Windows PC to build the Windows ISO, apply it onto the phone from mass storage, configure ESP
Warnings:
- Don’t create partitions from Mass Storage Mode on Windows (because ABL will break with blank/spaces in names), your phone may be irrecoverable otherwise
- If you see a warning and/or error during the process, it is not normal. Contact us on telegram if you see anything odd, but do not continue or proceed on your own, you will break things further.
- Don’t rerun the commands if you interrupt the process. You may break your partition table. Parted is a very delicate tool, anything you do may cause permanent damage to your device.
- Do not run all commands at once. Parted is a very delicate tool, anything you do may cause permanent damage to your device.

In Android settings, enable the Developer Settings menu (7 consecutive taps on Build Number), and turn on “OEM Unlock” inside it.
