Not Duel Booting to Windows 10 or 8.1

I installed Windows 10 Preview on a separate partition on my windows 8.1. The Preview worked well at first, but after I restarted my computer, I got the option to boot 8.1 or 10. I chose my old OS. It took few minutes to load, but I was able to login to 8.1. Next time I restarted my computer, it would not give me the option of 8.1 vs 10. It automatically goes to 8.1. Anyone else noticed this? By the way, I downloaded the Preview directly to my separate partition without using a USB or DVD. I think this might the culprit, but if anyone else has any idea, please share.

I had the same problem. I have fixed this with EasyBCD (free version).
