rufus-linux

Linux port of Rufus — a utility for formatting and creating bootable USB drives. Uses GTK4 for the UI and stays as close to the original Windows layout as possible.

Features

• Automatic detection of USB block devices (libudev)
• Direct write of isohybrid ISOs and raw disk images (.img)
• Image-type detection (isohybrid · ISO9660 · GPT · MBR via on-disk magic bytes)
• Partition table creation (MBR / GPT, libparted)
• Filesystem creation (FAT32 / exFAT / NTFS / ext4 / btrfs / UDF)
• Syslinux install for FreeDOS-style bootable FAT32 sticks
• Hash verification (MD5 / SHA-1 / SHA-256 / SHA-512, OpenSSL EVP)
• Background writer via GTask — UI stays responsive during writes

Build

Install dependencies (Debian / Ubuntu)

sudo apt install \
    meson ninja-build pkg-config \
    libgtk-4-dev \
    libudev-dev \
    libblkid-dev \
    libparted-dev \
    libssl-dev \
    libcurl4-openssl-dev

Build

git clone https://github.com/soichi11208/rufus-linux
cd rufus-linux
meson setup build
meson compile -C build

Install (for polkit integration)

sudo meson install -C build

The polkit action definition (res/org.rufus.linux.policy) is installed to /usr/share/polkit-1/actions/.

Running

Writing to a block device requires root privileges.

# Quick path for development
sudo ./build/rufus-linux

# After install — a GUI auth dialog appears via pkexec
pkexec /usr/bin/rufus-linux

How to use

1. Device — click the ↺ button to scan for USB drives, then select the target from the dropdown
2. Boot selection — choose "Disk or ISO image" and click SELECT to pick an image file
3. Image option — usually no change needed (isohybrid ISOs are auto-detected)
4. Partition scheme / Target system — the defaults (MBR / BIOS or UEFI) cover most use cases
5. Format Options — adjust volume label, filesystem, and cluster size if needed
6. START — after the confirmation dialog, writing begins in the background

Supported filesystems

FAT32	mkfs.fat	dosfstools

NTFS	mkfs.ntfs	ntfs-3g
