IoT Core build 10586 for the Surface RT
The Secure Boot unlock needs to be applied for this to work.
If you’ll not use this, do not download it. Bandwidth is not cheap. 🙂
For now, build 10586 of Windows 10 IoT Core will be released for the Surface RT. 🙂
Go to “Set up a new device” and choose “Custom” for device type, then select the Windows 10 IoT Core for the Surface RT release.
After you install, unplug and then replug your USB stick, to override the contents of the EFIESP partition with the ones of the EFI.zip that you downloaded earlier.
Then start your Surface RT from USB, as if it was a Windows RT recovery stick. 🙂
Give your feedback in comments. 🙂
Note: UpdateOS is broken in this build. As such, you’ll not be able to do updates. (and they won’t work anyway, for reasons highlighted in my RS1 post)
