Active volume
This is the volume from which the machine starts after you switch it on.
The active volume usually contains one of the following programs:
 The operating system
 A program that enables you to choose which operating system to run (if more than one is
installed), such as GRUB
 A diagnostic or recovery tool that runs before the operating system, such as Acronis Startup
Recovery Manager

If you choose to run a Windows operating system, the start process continues from the volume
known as the system volume.
System volume
This is the volume from which any of the installed Windows operating systems starts—even if more
than one is installed.
The system volume contains files that are necessary to start Windows, such as boot.ini and Ntldr.
There is always one system volume, whereas each of the installed Windows operating systems
usually stores its files on its own volume, called a boot volume.
Boot volume
This is the volume on which the files of a particular Windows operating system are stored.
A boot volume contains folders such as the Program Files folder and the Windows folder.
Note: The notions of system volume and boot volume apply only to Windows operating systems.
