First, boot managers resolve the problem that many users interfere with when installing different OSes on their PC. For instance, one may want Windows, a few Linux distributions, and even a Mac OS X deployed on the same system. The boot sequence repeatedly chooses the same OS and boots it without a boot manager. Therefore, a boot manager is a must for any similar situation.
Generally, a boot manager allows every operating system to be installed to a separate partition, thus limiting the chances of potential conflicts. The thing with this trend amongst advanced users is quite simple to comprehend. If you are dying to take a new operating system for a test run without completely switching to it, you can install it alongside the current OSes on the computer.
Thus, you don’t have to install it over the one you are already running, then reinstall the old one if you don’t find any reason to keep the new one. Other than this, several other reasons are to utilize boot managers and, implicitly, multiple operating systems. One of them can refer to developing and testing applications.
