In short, dual boot or dual boot is the act of installing two operating systems into separate partitions on the hard drive. Dual boot is useful when moving from one operating system to another (for example, from Windows to Linux).

Dual boot is also valid if you use an operating system for certain tasks. (For example, you have a Linux PC at home but use Windows at work.)

Virtual machines are a way to 'enjoy' multiple operating systems on a PC, but are not as versatile as dual boot. Both options have their own strengths and weaknesses.

Or, right-click the drive next to that free space, select Extend Volume to increase the size of the partition. After Windows 'recalls', this free space can be accessed via a new drive letter, ready to store any data on it (such as personal data, games). , videos, etc.). Everything is back to normal!
