Have you ever thought about creating a partition on an existing disk? If there are only one or two drives, and you want to create more drives to manage storage, you can do this easily.

When we buy a laptop or computer from an online store, it comes with only one drive, called the C drive, where we can’t store our important data safely. One of the main disadvantages of having only one drive on Windows is the risk of losing important and personal data.

If you ever have problems with Windows and need to reinstall the operating system, you won’t be able to save your data at that time. So, having more drives is the best option. In this article, we will guide you on creating a new partition on an existing disk in Windows.

Why do we need to create more than one partition?

  • With multiple partitions, you can organize your data properly, making it easier to locate.
  • Storing your important data in separate partitions will keep your data safe when reinstalling Windows.
  • You can run multiple operating systems by creating a partition for each OS.
  • Managing data will also improve system performance.
