Trinity Rescue Kit

It's based on Mandrake 9.1, fits on a bootable CD and is free.

It is designed to rescue/repair/prepare dead or damaged systems, be it Linux or Windows. It has networking capabilities like ssh, samba and ftp and supports about every network card, disk controller and USB controller. You can use it to repair a Windows 2000 or Windows XP system by setting the checkdisk flag or editing the registry or just reset the administrator password (or any other user). You can even undelete files from an ntfs, ext2 or fat partition.

Working knowledge of Linux is not necessary but will enable power users to benefit from all the toys included.

The rescue kit will typically attempt to detect onboard network adapters and use DHCP to obtain an IP address. If the rescue kit is successful at both tasks, you can then transfer files to an FTP, Secure Shell (SSH), or Windows server. For example, if you need to rescue files from a crashed Windows 2000 system, you'll be able to mount the partition, read the files, and copy them somewhere safe on your LAN.
