Vmware is another possibility.  Download Vmware from 
http://www.vmware.com/download/ (I understand you have to be 
registered).  Once the students have a virtual machine installed in 
their windows box (There is an virtual machine creation wizard that they 
can follow) they can start the fedora live cd by inserting the cd in the 
computer drive ( The virtual machine has to be configured to look at the 
physical drive and not something differente like an iso image,  but 
thats usually the default configuration so I would suppose there needs 
to be no additional configuration.). 
This setup allows them to fdisk all they want and not be in danger of 
damaging their box.
