Before you install
Read the release notes and installation guide before downloading. Select an image that matches the processor architecture and intended use: desktop, server, live media, virtual machine or another published edition. Test Wi-Fi, graphics, audio, storage and suspend from live media when that option is available. Back up important files before repartitioning, encryption changes or dual-boot installation. For production deployment, verify application compatibility, upgrade paths, backup restoration and the project security-support policy in a non-production environment first. Download from an official project page or mirror, compare the published SHA-256 checksum, and verify a signed checksum when the project provides one. After installation, apply updates before adding third-party repositories or drivers.
- 1Check the SHA-256
Compare the file with the checksum published by 4MLinux. If it does not match, download it again.
- 2Write it to a USB drive
Use Ventoy, balenaEtcher, Fedora Media Writer or Rufus. Copying the ISO as a normal file does not work.
- 3Boot from the USB
Open the boot menu (often F12, F10 or Esc) and choose the USB drive in UEFI mode. Back up your data first.
About 4MLinux
4MLinux is a small independent live distribution organized around maintenance, multimedia, miniserver and games. It can serve as a lightweight desktop while also including rescue and compact server tools. The selected x86-64 ISO is the official stable update 52.1; its mixed use cases are reflected in the catalogue categories.
Who is it for?
4MLinux is primarily suited to daily desktop use, study, web browsing and productivity; servers, virtual machines and self-hosted services; older computers, modest hardware and lightweight virtual machines. Before choosing it, compare the current release lifecycle with the length of support required for the machine. This distribution is based on independent, which influences package formats, repositories and much of the available documentation. The listed desktop environment is JWM; confirm its memory, graphics and accessibility requirements on the official project site. The best choice depends on hardware support, preferred software, update policy and the amount of system administration the user wants to perform.
Advantages and limitations
Advantages
- Suitable for modest hardware or lightweight virtual machines, subject to the selected edition.
- Offers installation or deployment options intended for server and infrastructure workloads.
Limitations
- Its independent package ecosystem can have fewer third-party instructions than Debian-, Ubuntu- or Arch-based systems.
4MLinux download questions
Which 4MLinux ISO should I download?
IsosLinux lists the desktop ISO for laptops and PCs, with a live session and graphical installer. Most people installing on a computer want the desktop ISO. Other editions and architectures are listed under All images.
Is the 4MLinux download official?
Yes. The download buttons open files on sourceforge.net, the project's own server or official mirror. IsosLinux only lists the link and counts the click; it does not host or modify the image.
How do I check that the 4MLinux ISO is not corrupted?
Compare the SHA-256 checksum of your file with the one published by 4MLinux. On Linux run sha256sum on the file, or use the IsosLinux ISO checksum verifier, which works locally in your browser.
What is 4MLinux based on?
4MLinux is an independent distribution: it is not derived from another Linux distribution.
Which desktop does 4MLinux use?
