Whenever I try to boot into xp, one of two things happens. I try to boot into normal mode or last known good config, and it goes to the login screen, I click on my account, it shows just the desktop, no icons, just the wallpaper, and then goes back to the login screen. This repeats everytime I click on my account login. When I try to boot it into safe mode, it flashes something about realtek boot and asks me to hit shift and some other variety of keys but then it disappears as soon as I have a chance to fully read it, it just loops back to the mode select screen, I don't even get to the login screen. What should I do?
