Winclone is a bootcamp imaging program for the Mac. It is completely free. It will image your bootcamp windows partition on your Mac. It does this all from in OSX. You can back up and restore.
I just recently spilled water on my macbook and had to file an insurance claim to get a new one. The macbook was toast but the hard drive survived. I went to microcenter and picked up a 14 dollar SATA/IDE to USB adapter cable and plugged my old hard drive into the new macbook. I used winclone to make an image of my XP partition. I then reinstalled XP on the mac via boot camp. After all of this I restarted in OS X and restored my XP partition with winclone.
Some of you might be wondering why I wouldn't just have reinstalled everything fresh. Before my accident my bootcamp partition was fine so there was no need to reinstall everything. A restore takes about 5 minutes as opposed to a couple hours. I am also living in Chicago while my wife is in SC trying to sell our house. I don't have all my software discs on me so it would have been disasterous if the water had gotten to the hard drive.
Now because I was going from an older model macbook to a newer one I had to reactivate windows and because of DRM issues with WMP11 and Netflix I had to delete my DRM folder. Luckily all my music is tied to iTunes so I really just had to delete the DRM folder and let WMP11 restore it.
Over all it is a great little program for those of you that use bootcamp and it is very easy to use. Best of all it is totally free.
