I've been using Parallels Desktop for Mac since I first got my Mac in 2011. Parallels for mac windows partition is just blue. The trouble is that I somehow got confused about how to install it on my Mac back then, and I think I ended up with a sort of hybrid installation that involves using BootCamp.
Setup of operating systems in both applications is done via detailed onscreen instructions and takes approximately 5 to 15 minutes. Installation of the actual operating system after the initial setup process is complete will be done using its own procedure. For example, when installing Windows, the installation process will be the same as if you were installing Windows natively on a PC.
The Apple Bootcamp installation requires a utility that comes preinstalled on all Intel-based Macs called “Boot Camp Assistant” that will allow you to partition your hard drive, and provide you with a virtual CD containing all of the necessary drivers for your operating system.
Installation of an operating system through Parallels will walk you through the process of preparing the drive and creating a virtual machine for the OS. You will also be able to specify how much RAM is allocated to the operating system. One benefit of this installation process is the ability to select the “Expanding” disk format. This will allow the disk image to grow as more data is required, allowing you to only use as much disk space as necessary.
