I have raspberry Pi 3 with Windows IoT 10 Core.
I flashed 17763 build using Dashboard.
Everything was working properly, even debugging from Visual Studio 2017, but in some moment, I found my Raspberry with boot menu:
[1] Default EFI Boot Application
[2] Default EFI Boot Application
[3] Shell
[4] Boot Manager
Start: _
I connected keyboard via USB, I press 1, but it no response...
The keyboard was working properly with Raspberry before.
Is there some other solution except reflashing the SD card?
So, only one solution I found, is to reflash the SD card.
