And what if you’d like to not just install a dual boot but triple or quadruple boot? Of course, you might overcome most challenges by simply using a virtual machine in VirtualBox, Parallels or VMWare Fusion. What if you want to share data between the two operating systems, for instance? Windows can’t access Mac’s HFS+ file system and Apple’s implementation of NTFS drivers to access Windows file systems is so buggy, they only dare to give you read access. But BootCamp doesn’t give you enough flexibility. Once finished, you can select which OS to boot by pressing “alt” when the boot chime sounds.
It will ask you how much space you want to allocate for each environment, ask you for a Windows 8 or 10 ISO or CD-ROM, and then start the process. Installing Windows 10 alongside with Mac OS is pretty straightforward with Apple’s BootCamp.
