Of course, there’s no shortage of tools and utilities that’ll help users heal their broken installations. However, like with most things open source, it is the sheer number of choices that often confuse the average desktop user who might end up choosing the wrong tool for the job. 

This is where these specialized rescue distros come into the picture. They not only collate a vast number of healing tools, they’ll also go the extra mile and help you find the right tool for the job.

1. Finnix

Best for system administrators

Reasons to buy
+Comprehensive list of tools+Relatively small size
Reasons to avoid
-Command-line interface-Virtually no documentation

The Finnix distro has been around since the early 2000s and though the project had been languishing for quite a few years, it’s developer has now actively started working on it with regular releases.

In fact, the project recently celebrated its 20 year anniversary with a new release. The distro has had a complete overhaul and now has a new build system based around Debian Testing. 

Finnix is also a native 64-bit distro now and features several enhancements that make it more usable on modern machines. For instance, it now uses GRUB as default bootloader for both BIOS and UEFI systems. There are several other noteworthy features as well including the use of zram swap compression, and improved remote SSH access. 

One of the goals of the distro is to keep the size of the final release small enough to fit inside a CD. To that end the layout of the distro is optimized for CD-ROMs, which doesn’t impede when it’s used from a USB, but will result in faster boots from CDs. This makes it suitable even on machines that can’t boot from USB sticks.

Finnix’s tool list is comprehensive, and virtually unrivalled. However, its usability is limited thanks to it being a command-line only distro. New users shouldn’t expect much help from the project’s website as well as the documentation there is pretty old, though the developer has promised to update it as well.

2. Rescatux

Best for inexperienced campaigners

Reasons to buy
+Point-and-click rescue app+Can handle Windows installations as well+Intuitive
Reasons to avoid
-Experienced users might miss some tools

Rescatux ships with a minimal graphical desktop and bundles all the important and useful tools to fix several issues with non-booting Linux and Windows installations. 

You can very easily use Rescatux for common repair tasks such as restoring bootloaders, repairing filesystems, fixing partition tables and resetting passwords on both Linux and Windows installs. The distro also ships with tools to rescue data and restore files and can wipe both Windows and Linux installs.

Unlike many of the other distros in this list, Rescatux can boot on both 64-bit and older 32-bit computers.

Upon booting, the distro takes you to the minimal LXDE-powered graphical desktop and automatically fires up its custom helper application called Rescapp. The application’s interface has improved through the releases, and in its latest version hosts several buttons divided into various categories, such as Boot, Grub, Filesystem and Password. 

The buttons inside each category have descriptive labels that help identify their function. When you click a button, it brings up the relevant documentation which explains in detail what steps Rescatux will take and what information it expects from the user. After you’ve scrolled through the illustrated documentation and know what to expect, you click the button labelled ‘Run!’ to launch the utility. 

Advanced users can bypass Rescapp and fire up a terminal and access the rescue tool directly. Rescatux hosts lots of guides and instructional videos on its websites, and there’s also some documentation to help inexperienced users get started with the distro.

3. SystemRescue

Best for advanced users

Reasons to buy
+Good collection of utilities+Ample documentation+Ships with lightweight Xfce desktop
Reasons to avoid
-All tools are CLI-only

One of the oldest distros that’s designed to equip system admins with a variety of tools and utilities to help repair and rescue data from Linux or Windows.

SystemRescue has gone through major changes in the last few releases. The distro is now based on Arch Linux and uses an Xfce desktop. Earlier versions of the distro featured an elaborate boot menu that spanned across several virtual consoles. This has been done away with in the newer release. The latest version of SystemRescue now runs the 5.4.71 LTS (long-term support) Linux kernel, It also includes the dislocker utility to allow users to access data on media encrypted with BitLocker.

The default boot option boots into a console which lists a command to configure the keyboard and another to start the graphical environment. The distro contains an extensive collection of tools for system and network analyzes, for hard disk partitioning, for file system handling, for data recovery, for reading out hardware information and for secure deletion.

Note however that the graphical desktop is purely optional as all of the tools in the distro are command-line ones. However the graphical desktop will help inexperienced users access the project’s extensive documentation. 

The project hosts a quick-start guide as well as detailed instructions on basic and advanced use. There are also instructions for experienced campaigners, such as the guide on how to make a custom version and backing up data from an unbootable Windows computer.

4. Ultimate Boot CD

Best to fix all kinds of computer troubles

Reasons to buy
+Intuitive menu+Can diagnose hardware issues as well+Good documentation
Reasons to avoid
-Lacks a graphical environment 

Ultimate Boot CD (UBCD) is different from the other distros in that it ships with no graphical desktop and instead boots to a very well laid-out menu. The customized text-based menus help guide users to the relevant utility for the issue plaguing their computer. 

UBCD’s menu might be text-based but it is very well laid out and logically arranged. As you drill down the individual entries display brief but useful information to help identify their function. The clear categories and helpful descriptions mean that the distro can be easily navigated and used by inexperienced users to fix all kinds of issues.

The distribution is loaded with tools. You can use UBCD to query and stress-test hardware and peripherals connected to a system. It can be used to restore BIOS settings as well as restore and backup the CMOS. UBCD enables you to fix bootloaders, recover lost passwords and deleted files. It will also help you tweak the Windows Registry without booting into the installation.

UBCD’s website hosts a fairly detailed FAQ to familiarize users with the distribution. However, the tutorial section is really just a pointer to a long list of user-contributed tutorials curated from the forum boards.
