JustDD

JustDD is a small, focused USB image writer with a simple wizard-style UI. It helps you write Linux and Windows ISO images to USB drives safely and with progress feedback.

Note: You can use the app either by running with uvx (recommended), pipx, or building from source:

Run with uvx: uvx justdd.
Run with pipx: pipx run justdd.
Build from source: follow the Quick Start below.

Before running the app, make sure you have the prerequisites installed (described below).

Quick Start

Prerequisites

| Name | What it does | Where to obtain | |---|---|---| | Python 3.9 or higher | - | Linux got it by default | | uv or pipx | Allows to run the app without installing it or building from source | astral.sh (uv) or pipx.pypa.io | | polkit (policykit-1 on Ubuntu/Debian) | Allows safe root access | Your distribution's package manager, usually pre-installed | | rsync | Allows to copy files without syncing file system after copying is done | Your distribution's package manager, usually pre-installed | | libcdio | Allows to read CD/DVD images | Your distribution's package manager, usually pre-installed | | Windows specific packages (optional)| If you want to install Windows images, you need to install the following packages, if not app still will work for Linux images | - | | ms-sys | Allows to write Microsoft-compatible boot records for MBR (optional) | Fedora (RPM Sphere), Arch (AUR), Ubuntu/Debian (only building from source) | | ntfs-3g | Allows to read/write NTFS filesystems (optional) | Your distribution's package manager, usually pre-installed |

Run via uvx (Recommended and the best way)

uvx justdd

(Thanks to @Technetium1 for configuring uvx.)

Run via pipx (Also recommended)

pipx run justdd

Build and run

Using UV (recommended):

git clone https://github.com/xxanqw/justdd.git
cd justdd
uv run justdd

Or using a plain venv + pip:

python -m venv .venv
source .venv/bin/activate
pip install -e .
python -m justdd

Other methods were deprecated. As i didn't figure out how to properly package DEB and RPM packages. lul

Basic Usage

Select an ISO file.
Choose the target removable drive.
- Choose partitioning options (e.g., GPT, MBR) if flashing Windows.
Confirm and Flash.

Important: Flashing will overwrite the target drive. Always double-check the selected device.

Capabilities

| Capability | What it does | |---|---| | ISO writing (raw) | Write ISO images directly to removable drives (dd-style) with progress and status. | | Windows support | Prepare Windows installer drives (partitioning and file handling). | | Drive detection | Show removable drives only to reduce the risk of selecting system drives. | | Live logs | View detailed operation logs for troubleshooting. | | Safe cancellation | Cancel operations with best-effort cleanup and warnings. | | Notifications | Desktop notifications on completion or failure. |

[!NOTE]
ISO Downloader was removed from the project due to its complexity and lack of enthusiasm.
But you can implement it yourself if you want. (will appreciate this)
