4MRescueKit provides its users with software for antivirus protection, data backup, disk partitioning, and data recovery. It is distributed in the form of a multiboot CD, which includes four (extremely small) operating systems. Each of the systems tries to follow the UNIX philosophy (Small is beautiful. Make each program do one thing well).

1) Antivirus Live CD is a 4MLinux fork including the ClamAV scanner. Both Ethernet (including Wi-Fi) and dial-up (including fast USB modems) Internet connections are supported to enable automatic updates of the virus signature database. All partitions are mounted automatically during boot so that they can be scanned by ClamAV.

Detailed description of Antivirus Live CD can be found here.

2) BakAndImgCD is a very small (about 20 MB in size) 4MLinux fork, which has been designed to perform the following two tasks: data backup (via 4MLinux Backup Scripts) and disk imaging (using Partimage, Partclone and GNU ddrescue). The output files (archives and images) can be optionally compressed and sent to a remote FTP/SFTP sever.

Detailed description of BakAndImgCD is available in this post.

3) 4MParted includes GNOME Partition Editor (aka GParted), which in turn is a GTK+ front-end to GNU Parted.  The supported filesystems are: btrfs, ext2, ext3, ext4, f2fs, fat16, fat32, hfs, hfs+, jfs, linux-swap, lvm2 pv, nilfs2, ntfs, reiser4, reiserfs, and xfs.

If GParted cannot read/modify a newly created partition, just close this application. Then 4MLinux will try to force the Linux kernel to re-read partition table, and next it will restart GParted for you. 

4) 4MRecover includes TestDisk and PhotoRec, which are powerful recovery utilities. PhotoRec (the tool to recover lost files) is started automatically. Just close PhotoRec, and Midnight Commander will be opened so that you can manage your files. You can also execute "testdisk" (in Midnight Commander's shell prompt) if you are going to try to recover lost partitions.

Despite its name, PhotoRec is able to recover many file formats (not only images).
All operating systems described in this post can be safely closed by pressing the power-off button (acpi daemon will start a script to cleanly shutdown your computer).


  1. Would be helpfull if it would be possible to change the keyboard layout, maybe via "loadkeys xy"

  2. I wrote 4MRescueKit on a multiboot-USBstick (using YUMI),
    I get the selection-menu for Antivirus / BakAndImgCD / Recover etc,
    but they don't boot.

    Also, an option "boot from hd" in the bootmenu would be nice.

    1. If you need help, please visit this forum:

    2. Maybe the problem is just the settings / boot-parameters.

      Systemtools such as Linux-Rescue-CDs are quite small,
      so it makes sense to put several of them onto a multiboot-USBstick.

      4MLinux is not yet in the list of distributions supported by Yumi,
      so someone needs to tell them what settings to use.

    3. 1) I have no experience with Yumi (I've never used it).
      2) If you have a problem to run 4MLinux, ask your question here:

  3. Why can't aren't there any torrent file links in the downloads list?

  4. linux is show! :)
