Yesterday I tried to install new insider version of win10 Iot for my raspberry, after that or it's just a coincidence my raspberry cannot boot any(RTM or insider preview version). The red light is constantly bright, yellow one wink few times and then it stay off. My display does show nothing. I use hdmi to vga converter. Core Watcher see the PI.

    Hdmi to hdmi and nothing. Not only when i boot windows but also when i boot rasbian now... But rasbian is kind of booted so i can connect by ssh normally. Looks like problem with hdmi on my board. – Krystian Kuśmierek Dec 5 '15 at 9:45

    Yea definitely sounds like it. Since its booted and you can SSH. Send it back and get a replacement. – Piotr Kula Dec 8 '15 at 18:19

Look at the list of supported Sd cards here (click other hardware) and use one of them. I found that unless I use a supported SD card it sometimes does not boot correctly. The latest IOT core seems to do a better job too. Here is a link: IoT Core Setup. Try using the latest core tool to create your sd card image and it might work on your current class 10 micro sd card.
