So I have a SSD for my Windows boot drive, and a hard drive dedicated for Windows 10. I have recently put in my old laptop HDD for Ubuntu 15.10, installed it, but I can't find it in the boot menu. I have checked in Windows 10 Disk Management and all 3 drives show up, the SSD, HDD, and the one I recently put it. The problem isn't sata connectors and not recognizing the drives. I don't know how to put my Ubuntu HDD as a bootable drive. Please help! I have looked at everything in the boot menu and nothing works.
