What is dual boot and how does it work?
You're looking to run both Windows 8.1 and macOS Yosemite side by side. You have a fast SSD (Kingsfast F9 512GB) and a larger HDD (2TB Seagate Barracuda). Decide whether to use the SSD for one OS and the HDD for the other, or split the storage between both. Avoid VirtualBox since you're unsure about it; it's a virtualization tool that can complicate things.
This could assist you in understanding the material. Refer to the provided link for more details. Also, please note your signature may breach the CoC; see the referenced page for guidance.
Also consider splitting your SSD in half—searching for partitioning guides is simple. You could run OSX on one side and Windows on the other.
The issue isn't about what you mentioned before, just the current requirements. The signature text size must stay at 14 or less.
