Rescatux is an open source GNU/Linux system rescue CD that has been designed from the ground up to help users fix broken operating systems that won’t boot anymore. It is a Linux distribution built around the LXDE desktop environment.
Distributed as a dual-arch Live CD
It is available for download as a dual-arch Live CD ISO image of approximately 400MB in size, which must be written on a CD disc or a USB flash drive of 512MB or higher capacity in order to be booted from the BIOS of a PC. Supported architectures include 64-bit (amd64) and 32-bit (i386).
From the minimal boot menu, the user can start the live environment with support for 32-bit or 64-bit platforms, as well as to start the Super Grub2 Disk utility. If you are not sure which option is best for you, do not hesitate to use the autodetect option.
Simple, fast and straightforward desktop environment
The LXDE (Lightweight X11 Desktop Environment) session is comprised of a bottom panel from where the user can launch applications, interact with running programs or cycle between multiple virtual workspaces.
