You do not need a Windows installation disc to manage your computer’s hard disk partition. Using the built-in disk management tool or any third-party partition management software, you can easily shrink, resize, extend, merge, create and format disk drives on your Windows computer. The data contained in drives might not be lost or formatted while the partitions manage, but it is not guaranteed. Backup your computer or any other important data to external storage or free cloud storage.

If you have just bought a new desktop or laptop computer, then you might find that there is more than enough space in the Windows Drive partition. You can shrink space from the Windows drive and create a new volume without formatting the Windows drive.
