don't use your usb to boot up the PC what you need to do is configure your portable ubuntu to save progress after that make sure you have sun xm virtual box install and run the schools computer OS through the virtual computer note that this produce a lot of lag especially using govt computers after everything is ready boot the school PC up normally and open your drive i think ubuntu 9+ has the help tool for booting from usb so use that reboot the computer and u should be in ubuntu boot up the virtual pc and make sure everything is configured how it should be on the schools pc to prevent them from finding out if this does not work throw out ubuntu and get kubuntu with the network tools then unlock the network which is very easy if you use the network tools given to you you can also find the administrative user name and password using these tools if all else fails you will have to get a portable proxy to use when running ubuntu/kubuntu
P.S. I promiss I won't be breaking any laws with the information obtained here.
