Let's partition a hard drive! There are plenty of reasons to partition a hard drive—creating virtual machines, dual booting, or even just as a troubleshooting tool. Partitioning divides a single hard drive into multiple (virtual) ones that can be used individually. The capacity of the drive is split between them, not shared.

Windows makes the partition process easy. These are the easiest ways to go about partitioning your hard drive on Windows.

Note: This works for hard drives, external drives, and even USB drives.
