Okay, this may not be the best place for this, but it seems to be related.

Here's my situation. I teach in a computer lab in an elementary school with about 26 PCs. In the past I have used Ghostcast 7.5 to reimage the computers with Windows XP. I decided that I wanted to Dual Boot and tried to reimage with that setup, but everytime I try to broadcast the image I get an error. Is there another way to do this, I really want to get Ubuntu on these computers but I don't wanna have to install and configure every computer individually.
