SD Card Boot

Hi. I have Latte Panda Alpha 864s. I want to install windows 10 on lattepanda. Its internal memory is low for me. I have 1 250gb sdcard. I want to install Windows on it and start the Latte Panda operating system via this SDcard. When I tried to do this, I could not find the SD card during the operating system installation step. Is there any way I can do this?
