SystemRescue (formerly known as SystemRescueCd) is a Linux system rescue toolkit available as a bootable medium for administrating or repairing your system and data after a crash. It aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the hard disk partitions. It comes with a lot of Linux system utilities such as GParted, fsarchiver, filesystem tools and basic tools (editors, midnight commander, network tools).

It can be used for both Linux and windows computers, and on desktops as well as servers. This rescue system requires no installation as it can be booted from a CD/DVD drive or USB stick, but it can be installed on the hard disk if you wish. The kernel supports all important file systems (ext4, xfs, btrfs, vfat, ntfs), as well as network filesystems such as Samba and NFS.
