Libertix open-source tool installs Linux Mint, Zorin dual-boot from Windows without USB
Libertix is an open-source Windows application that automates dual-boot Linux installation by staging a live environment on disk and using UEFI BootNext or GRUB4DOS to eliminate the need for USB installation media.
Summary
Libertix revives the Wubi concept of installing Linux directly from Windows without requiring USB drives or manual BIOS configuration. Developed by French Linux vendor Ekimia, the open-source tool currently supports Linux Mint and Zorin OS, guiding users through compatibility checks, Windows partition resizing, and automated dual-boot configuration for both BIOS/MBR and UEFI/GPT systems.
The tool verifies ISO checksums, stages installation files on the local disk, and reboots into a temporary live environment using UEFI's BootNext variable or GRUB4DOS on legacy systems. After installation, it presents a customized GRUB menu with entries for Linux, Windows, shutdown, and advanced options. Libertix includes rollback capabilities that track each stage and can restore Windows boot configuration if the process fails or is cancelled. The project received a €3,000 summer 2026 funding campaign to support full-time development.
How Libertix stages and boots the Linux installer
- Firmware detection and compatibility gating: Libertix inspects firmware type (BIOS vs. UEFI), disk layout, BitLocker encryption status, and available shrinkable space on the Windows partition before permitting any modification, refusing to proceed if constraints are violated.
- UEFI BootNext vs. BIOS GRUB4DOS chainloading: On UEFI/GPT systems, Libertix sets the UEFI BootNext firmware variable to launch its staged environment once without altering permanent boot order; on BIOS/MBR systems, it creates a temporary Windows boot entry pointing to GRUB4DOS.
- Partition operations and filesystem choices: The tool shrinks the Windows NTFS partition, creates a new ext4 partition for the Linux installation, and verifies ISO checksums before download to ensure image integrity.
- Cross-platform file sharing with safety guardrails: Optional file sharing exposes Windows folders to the Linux environment while Linux files are mounted read-only from Windows to prevent ext4 corruption from Windows drivers.
- Stage-tracked rollback mechanism: Libertix records each completed phase and can reverse only executed steps, restoring the original Windows boot configuration if interrupted or if errors occur during installation.
Why it matters
Libertix addresses a persistent friction point for Windows users evaluating Linux by removing the need to create bootable USB media and navigate firmware boot menus, potentially expanding the pool of Linux adopters who lack technical confidence or spare hardware. Its open-source licensing and public GitHub repository allow community scrutiny of partition-handling code, which is critical given the data-destruction risks inherent in automated disk resizing.
