  1. Hi, I installed dual boot Yosemite and Windows 10. I first installed Yosemite and then Windows10. I use single drive of 2TB. 1 for Mac and 1 for Windows. After the first boot after the installation Windows automatically boots itself. When I want to boot Yosemite I must put back my bootable USB with Yosemite on it and make boot from USB option in BIOS and only then can boot the already installed MAC on the first 1TB partition. If there is no USB Windows 10 automatically boots first. How I can make the PC to ask me which OS to boot? Thanks, this community is awesome.
