SystemRescueCd is a Linux system rescue disk available as a bootable CD-ROM or USB stick to administrate or repair your system and data after a crash.
It provides you with an easy way to carry out admin tasks on your computer, such as creating and editing the hard disk partitions. It comes with many Linux software such as system tools (parted, partimage, fstools, etc.) and basic tools (editors, Midnight Commander, network tools, etc.).
SystemRescueCd requires no installation. It can be used on Linux servers, Linux desktops, or Windows boxes. The kernel supports the important file systems (ext2/ext3/ext4, ReiserFS, Reiser4, Btrfs, XFS, JFS, VFAT, NTFS, iso9660), as well as network file systems (Samba and NFS).
