Voila ce que j'avais trouvé hier pour un PC d'un copain
The Trinity Rescue Kit 1.1 is a Linux distribution based on Mandrake 9.1 binaries. 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
The Trinity Rescue Kit 1.1 is the successor of version 1.0, but with a complete revision and new binary base. Version 1.0 was based on Mandrake 9.0 binaries and 0.5 and previous were based on a RedHat 7.2 distribution. Version 1.1 is based on Mandrake 9.1 because Mandrake is always the first to use the latest technology and have the most features.
Provided you know some Linux, TRK can really save the day for you in terms of evacuating or undeleting files, cure a machine of viruses, reset Windows NT/2K/XP passwords, create a disk image over the network, saving lost partitions, etc. ==> see more in Features
Provided you DON' T know some Linux, TRK can still be used f.i. with the custom made scripts like winpass, a script that looks on all local harddisks for a Windows NT/2K/XP installation and uses Pavel Roskins chntpw utility that resets passwords.
On the other hand, TRK can really mess up your day, because all the failsafes are off once you start mounting disks. Be warned! God knows I already screwed up my Win2k once. Just by not paying attention, pure user damage.
A quel momment ?
