This page is about how to unmount partition on Windows/Linux using Gparted or how to use gparted alternative when partition cannot be unmounted.
What is mount and unmount a partition?
In Linux, "mount" is the process of attaching a filesystem to a directory, making its contents accessible, while "unmount" is the act of detaching it, ensuring data integrity.
In Windows, "mount" is "online" that means attaching a disk to access its contents, often by assigning a drive letter. "Unmount" means "Offline", which is safely disconnecting or dismounting a disk to prevent data corruption. (There is no 'unmount partition' or 'mount partition' in Windows since this function (online/offline) only works with disks.)
Gparted Live USB/CD is required when Gparted cannot unmount a partition when the OS is running. Here are several scenarios when Gparted cannot unmount a disk or partition.
For Windows users, you may directly use free tool IM-Magic Partition Resizer to resize/shrink/extend/move partitions without unmounting a disk or partition when the OS is still running. What's more, you can also convert disk mbr to gpt, clone disk etc. without unmounting it using IM-Magic Partition Resizer.

For Linux users, you need to run Gparted in a bootable mode, ie before entering the OS to unmount the disk.
