Windows 10 resize partition using GParted

How to use GParted to resize partition on Windows

You can use the Linux-based Gparted tool to resize, create, and delete partitions on Windows 11 as well as on Windows 10, and here's how.

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 11 and 10 include the Disk Management tool to manage partitions, if you plan to resize a drive to create a dual-boot setup, expand an existing partition, or create or delete a partition, you can also use GParted, which offers more tools and options.

This guide will teach you how to resize, create, and delete partitions using GParted on Windows 11 and 10 devices.

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

Create a USB bootable media with GParted

To create a GParted bootable media, connect a USB flash drive with at least 2GB of space to your device, and use these steps:

  1. Download tuxboot from SourceForge. (Select the latest stable version available.)

  2. Double-click the tuxboot-x.x.x.exe file.

  3. Click the Yes button to bypass the “unknown publisher” warning.

  4. Select the “On-Line Distribution” option.

  5. Use the drop-down menu and select the gparted-live-stable option.

  6. Use the “Type” drop-down menu and select the USB Drive option.

  7. Use the “Drive” drop-down menu and select the flash drive.

  8. Click the OK button.

Once you complete 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) by hitting one of the function keys (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 11 installation files, and do not forget to save the configuration.

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