To gain the ability to boot Windows at the same time as your Mac operating system,
you will need a virtualization solution. This will allow you to launch Windows within macOS.
Booting to one OS (ie. the traditional experience) is your best option when your need for Windows involves anything resource-intensive (eg. Solidworks). Virtualization solutions effectively require your Mac to run 2 full operating systems simultaneously, and that's not good math when it comes to performance needs!
The two main titles on the market are Parallels Desktop and VMware Fusion. We highly suggest that you make a point of investigating whether virtualization is the right choice for your Windows-based needs. Learn about each offering at the following links:
