I lately used BootCamp to add Windows XP pro to my computer for a larger array of games. But, after everything working greatly, my MacBook Pro shows me a grey screen with log information and this :sign that tells me to restart my computer after restarting my mac from the windows side. I have tried a few times to restart my computer and it gives me the same error. I also tried restarting my computer with windows by using the mac installation disk and then trying to open with mac again and it gives me the same error message. Any help?
