I think I know why it might have shown a wallpaper and mouse.
Usually when I have a disk that can be booted off, upon startup a black screen shows that says at the bottom "To boot from CD push any key..."
The way that I booted from the CD before, I had to go into the Boot Menu from the Motherboard screen on startup, as after multiple restarts, the black screen that I usually see was not there.
