We have moved to primarily dual boot iMacs in our campus computer labs, but are looking for an automated way to recreate the "student" use side from a protected "master" side. What I mean is that they currently re-image the machines on a regular basis to remove any junk etc. that may have been left by student use on the machines. So what I would ideally like to do is to have a cloned master PC (Windows 7) and cloned master Mac (OSX 10.6) at 2 separate partitions on the hard drive and also a student use PC and student use Mac partition that the clones would install the OS, apps, etc. from on an automated basis. What I am envisioning then is a 4 partition on the iMac hard drive. Partition 1 - Mac OSX 10.6 plus Office, etc. master Partition 2 - the one that would be re-imaged on, e.g., a monthly cycle, preferably automatically on a set schedule, using Partition 1 Mac master Partition 3 - Windows 7 plus Office, etc. master Partition 4 - the one that would be re-imaged on, e.g., a monthly cycle, preferably automatically on a set schedule, using Partition 3 Win master Is this doable, and if so, what would I need to do it? Any cautions, alternative advice, etc.?
