Installing GParted on a Linux system cannot adjust partitions while the computer is running because the / and /home partitions are read-only during boot. An alternative method is to create a GParted USB bootable drive, boot the computer from the USB, perform the partition adjustments, and then restart the computer to enter the Linux system.
To create a GParted USB bootable drive, it is recommended to use Rufus, which is simple and user-friendly. There are many tutorials available online, or you can refer to a previously published article:
