You should be able to get an external hard drive enclosure that you can put the laptop hard drive into that will plug into any other computer with a USB cable. Then you can access the laptop hard drive through the other computer. That is assuming that the problem with the laptop is not the hard drive itself. Just make sure that the external hard drive enclosure is has the proper interface (PATA or probably SATA) as the laptop hard drive. I think you should be able to read the files even though you have two different OS's.

Wouldn't he at least have a copy on the server at the school that he is going to??
