My new macbook pro has completely given up the ghost on me. I installed bootcamp and winxp on it, and just tried to install photshop but the disc would not be recognised in xp and everything just crashed. So eventually I just had to reset, and turn it on again. Now it simply goes to a white screen. It seems to be choosing to boot winxp, and then the disc in the slot is freezing it. I can't boot in osx, and I can't eject the disc whatever I do. I've tried holding down the mouse button as I boot, holding alt, delete, this that, everything...
