Hello, changing partition names won’t make you loose your data at all. However, making changes to theĀ main partition requires administrative privilegesĀ due to the system.
NOTE: Renaming drive’s letter where Windows or apps are installed creates problems while running or finding that drive path. Because of this I advice you not to change the drive letter of a drive on which Windows OS or apps are installed.
If you partitioned your drive, then you can freely change other drives names to your suitable Name.
