So you want to install Windows 10 on this ‘Berry. You better follow this guide closely.
All 5 usb ports work now. 1 type C and 4 type A however drivers for type c port requires 1GB RAM limitation.
- A PC with recent Windows 10 build installed.
- USB mouse and keyboard.
- USB storage device.
- Raspberry Pi 4B,
- Micro HDMI cable.
- Power supply (5V 3A+).
or if you still want to use sdcard for boot then you should also get
- A fast micro SD card – 16GB or higher – Class A1 or A2
- Micro SD card reader
Download Windows 10 installation files for arm64 from https://uup.rg-adguard.net/.
- Download ISO compiler in OneClick!
- Run downloaded CMD-file (run creatingISO.cmd file).
Or, download via https://uupdump.ml/, using aria2 and convert, running aria2_download_windows.cmd after extracting it.
Either of those services will help you to generate a ISO file but we only need install.wim file from sources folder on the ISO. Any build that passes OOBE without issues will be fine. (Build 19041 or higher should work and build 22610(Insider/Dev channel) is most recommended one right now.)
WoR (windows on raspberry) -Download 2.3.0 from https://worproject.ml/downloads
Once you download all of the things above you can proceed.
Open WoR. Select Disk from the list which will be your microsd card reader or usb storage device and select Raspberry pi 4 as a device that you will use. Then select build of windows WoR should use by pointing to a correct install.wim file. Use the latest drivers that WoR server provides. Select the latest UEFI for Raspberry pi 4 in WoR. Use Advanced tab in WoR to limit memory to 1024MB for USB type-c and if you don’t need type-c port then RAM is still limited by UEFI by default to 3GB of RAM. Do edit boot options in WoR if you need to (I always overclock as my Pi has a fan and heatsink attached).
WoR will deploy windows to the selected micro sd card or usb storage device which will take from 10 minutes to 3 hours depending on speed of your micro SD card or USB storage device and CPU . Note that having windows defender enabled while deploying will slow down the process as it will try to scan every file.
Safely remove micro SD card or usb storage device and move it into the Raspberry Pi.
This guide will be most likely updated if anything changes. First boot will take between 6 minutes to 2 hours depending on speed of your micro SD card or usb storage device . If there are issues during OOBE setup pressing shift + F10 then typing
%windir%\System32\Sysprep\sysprep.exe /oobe /reboot
might help. If it doesn’t, you will need to test a different build of Windows 10/11 arm64. Good luck!
Currently a lot of drivers are missing and not a lot of development is happening. We are missing drivers for wifi and gpu. Development of those drivers will take a long time or might never happen depending on community effort.
I do not check comments under this post anymore so if you want a response you can join Discord server and ask for help there as most people in that server will be able to answer your question. You might find there a guide how to customise windows 10/11 build to make it smaller and lighter which makes it so more usable on such a underpowered device.
