How to resize a partition on Windows 10 using GParted

You can use the Linux-based Gparted tool to resize, create, and delete partitions on Windows 10, and in this guide, you'll learn steps on how to it.

GParted is a free open source fully-featured tool based on Linux designed to manage disk partitions. Using this tool, you can create, delete, copy, resize, move, or label partitions with different file systems, such as ntfs, btrfs, ext2/3/4, f2fs, FAT16/32, hfs/hfs+, linux-swap, luks, lvm2 pv, nilfs2, reiserfs/4, udf, ufs, and xfs. 

Although Windows 10 includes its own partition manager that should be enough for most users, if you’re planning to resize a drive to create a dual-boot setup, expand an existing partition, create or delete a partition, you can also use GParted, which offers more tools and options compared to the Disk Management experience.

In this guide, you’ll learn the steps to resize, create, and delete partitions on a Windows 10 device using GParted.

Warning: Modifying the partitions on a hard drive can cause data loss if you don’t do it correctly or an error should happen during the process. It’s recommended to make a backup of your files before proceeding. Use these instructions at you own risk.

Once you’ve completed the steps, tuxboot will create a bootable media with the GParted files, which you can use to boot your computer to use GParted. However, before you start your device with the tool, you need to make sure that your device can boot from USB.

Typically, you’ll need to access your device Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) hitting one of the function key (F1, F2, F3, F10, or F12), the ESC, or the Delete key during boot.

Once inside the first, look for the Boot section and make sure the boot order is set to the drive that contains the Windows 10 installation files, and do not forget to save the configuration.

The BIOS/UEFI can be different depending on the manufacturer and even per computer model, as such make sure to check your manufacturer support website for more specific instructions.
