I got Windows XP Media Center. I followed the instructions and installed. I chose the "upgrade" option which was recommended. The problem is that now every time my computer starts, I get a screen that says "Windows did not start correctly, chose an option below to start in..." Safe Mode Safe Mode with Networking Last good configuration etc. Sorry, I can't remember exactly, I am at work right now. I don't understand any of this. The computer does this continuous loop no matter what I chose to start in. Could anyone help out?
