3) Choose "Windows Vista/7/8/8.1/10 installer with added drivers (for BIOS-based computers)" or "Windows Vista/7/8/8.1/10 installer with added drivers (for UEFI-based computers)" in this menu and click Next
UEFI mode must be chosen if you want to install Windows to 3Tb+ boot HDD. It may be chosen if you have UEFI-compatible computer. Most computers manufactured after 2012 are UEFI-compatible, but if you intend to install Windows to older computer, then use BIOS mode instead of UEFI mode.
