This question already has an answer here:
I have a SSD with 2 partitions. The first one belongs to Win10 and it worked fine. I installed Ubuntu 15.10 on the second one and it also works fine.
Problem is : When I boot, Grub is correctly displayed and shows both OS. If I select Ubuntu, I can boot without issue and can even access to the Windows' partition. But if I want to boot on Win10, it displays a black screen (like it'll start normally) for a few seconds (perhaps 2 ou 3) then go back to Grub without any message.
I'm pretty new to Ubuntu but kinda excited about it, but as a graphic designer, I still need my Windows (Adobe) from time to time. If anyone has a clue, I'd be glad to hear it.
Thank you guys.
