Rescatux is a GNU/Linux repair cd (and eventually also Windows) but it is not like other rescue disks.
Rescatux comes with Rescapp. Rescapp is a nice wizard that will guide you through your rescue and repair tasks.
Rescatux includes the popular Synaptic Package Manager and GParted open source applications.
Summing up, Rescatux is here to help you fix broken GRUB2 and Legacy GRUB boot loaders, regenerate GRUB menus on Debian and Ubuntu systems, fix Windows MBR partitions, check filesystems for errors and fix them, clear Windows passwords, change Linux passwords, regenerates sudoers files, and many more.
