Make a GParted Live USB Bootable Flash Drive

Create a bootable GParted Live USB from Windows with YUMI, or write the ISO from Linux or macOS with a disk-imaging command. GParted is a free, open-source graphical partition editor for creating, resizing, moving, copying, and deleting partitions. These operations can cause data loss if the wrong disk or partition is selected, or if a resize or move fails, so back up important data before making changes. The current GParted Live download is a 64-bit image for x86-64 PCs; check the official download page for current hardware and boot requirements.

About GParted

GParted (GNOME Partition Editor) is an open-source graphical tool for managing disk partitions. Supported operations and file systems depend on the GParted version and installed file-system tools. Before resizing, moving, formatting, or deleting a partition, review the selected device and partition carefully and make a backup; not every operation is supported for every file system.

Designed for use by both beginners and advanced users, GParted offers an easy to navigate and use interface. It is often bundled with Linux distributions but can also be downloaded as a standalone ISO for use on bootable USB drives.

Key Features

This versatile partitioning tool enables you to:

  • Create new partitions on your disks.
  • Resize or move partitions when the file system and operation are supported.
  • Create, delete, and format partitions after confirming the correct disk and partition.
  • Copy partitions for supported migration tasks; this is not a substitute for a verified full-disk backup.
  • Manage partition flags where supported.

What You'll Need

  • A Windows or Linux PC, or a Mac that can boot the GParted Live architecture
  • A USB flash drive with enough space for the image
  • The current GParted Live ISO from the official download page
  • YUMI on Windows, or a disk-imaging command on Linux/macOS

Creating a GParted Live USB from Windows

Follow these steps to create your bootable USB on Windows:

  1. Download and launch YUMI for Windows or use the compatible YUMI Py build on Windows or Linux. Select your USB drive carefully; creating boot media may change its contents.
    1. Select your USB flash drive.
    2. Choose GParted (Partition Tools) from the list.
    3. Browse to and select your GParted ISO file, then click Create.

  2. Restart your PC and enter the BIOS or Boot Menu. Set the USB drive as the first boot device and reboot.

Note: If your YUMI version does not list GParted, use its unlisted-ISO option if available and select the downloaded ISO manually. Support can vary by YUMI version and by the GParted Live release, so test the USB on the target PC.

Creating a Bootable GParted USB on Linux

Warning: The dd command overwrites the selected destination device and can destroy data. Back up the USB first, identify it with lsblk or sudo fdisk -l, and use the whole USB device (for example, /dev/sdX), not a partition such as /dev/sdX1. Never copy the example device name literally.

  1. Insert your USB drive.
  2. Download the GParted Live ISO and save it to your Desktop.
  3. Open a terminal (Ctrl + Alt + T).
  4. Identify your USB device by running: 
    sudo fdisk -l

    Note the device name (e.g., /dev/sdX).

  5. Change to the Desktop directory: 
    cd Desktop
  6. Write the ISO to the USB (replace X with your device letter): 
    sudo dd if=/path/to/gparted-live-amd64.iso of=/dev/sdX bs=4M status=progress conv=fsync

    Replace the input path with the exact ISO filename you downloaded and replace /dev/sdX with the verified USB device. The command erases the destination device.

  7. Reboot, enter your BIOS or Boot Menu, and boot from the USB drive.

Writing the GParted Live Image from macOS

Warning: Writing the image erases the selected USB device. Confirm the disk identifier carefully before running dd. Current GParted Live images are for x86-64 PCs; creating the USB on a Mac does not mean it will boot on every Mac, particularly Apple silicon models.

  1. Insert your USB drive.
  2. Download the GParted Live ISO.
  3. Open Terminal.
  4. Identify your USB device: 
    diskutil list
  5. Unmount the USB drive (replace X with your device number): 
    diskutil unmountDisk /dev/diskX
  6. Write the ISO to the USB (replace X accordingly): 
    sudo dd if=/path/to/gparted-live-amd64.iso of=/dev/rdiskX bs=4m
sync

    Use the exact downloaded ISO filename and the verified whole-disk identifier for the USB. This command overwrites the destination disk. Wait for sync to finish before ejecting the drive.

  7. Eject the USB: 
    diskutil eject /dev/diskX
  8. On a compatible Intel Mac, restart and hold Option to check whether the USB appears as a startup disk. GParted Live is intended for x86-64 PCs, so booting on a Mac is not guaranteed; Apple silicon Macs are not supported by this x86-64 image.

Frequently Asked Questions

What is GParted bootable USB used for?

It's a free, open-source partition editor that lets you create, resize, move, copy, format, or delete partitions. These operations can cause data loss, so confirm the target disk and back up important data first.

Which file systems does GParted support?

Supported file systems and operations vary by release and installed tools. Check the current GParted documentation for compatibility before planning a specific partition operation.

How can I verify the correct USB drive before proceeding?

On Linux, use lsblk -o NAME,SIZE,MODEL,TRAN,MOUNTPOINTS or sudo fdisk -l and compare the USB drive's size and model. In YUMI, verify the selected drive letter and capacity. Disconnect other removable drives if you are unsure. Always double-check before writing an image or changing partitions.

Can I use persistence with GParted on USB?

Persistence is generally unnecessary because GParted is primarily a live partitioning tool.

Troubleshooting Tips

My system doesn't boot from the GParted USB.
  • Make sure your BIOS/UEFI is set to boot from USB first.
  • Verify that your system supports USB booting (especially with legacy BIOS).
  • Try different USB ports or another USB stick.
GParted isn't listed in YUMI's dropdown.
  • Use the "Try unlisted ISO" option and select the ISO manually.
  • Confirm your ISO file is correct and uncorrupted.
The dd command hangs or is slow.
  • Confirm the correct device letter is used.
  • Check the ISO integrity.
  • Use a faster USB port (USB 3.0+) or a different USB drive.
USB drive unreadable after writing the ISO.
  • This is normal with dd since it overwrites the USB.
  • You can reformat the drive afterward for regular use.
I can't find the downloaded ISO.
  • Check your downloads folder or search your system.
  • Ensure you downloaded the correct ISO file.
GParted Live USB doesn't detect my hard drive or partitions.
  • Make sure the drive is connected properly and recognized by BIOS/UEFI.
  • Check for RAID or special setups; verify compatibility on the official site.
  • Update to the latest GParted version if hardware is new.

Final Thoughts on This USB Partition Tool

GParted Live lets you run the GParted partition editor from a bootable USB without installing it on the computer's internal drive. It can be useful for partition maintenance, troubleshooting, and preparing storage for an operating system, provided the hardware and file system are supported.

Partition changes always carry some risk. Back up important files before resizing, moving, formatting, or deleting partitions, and check the official GParted Live download page for the current image, release notes, and compatibility details.
