You should now have the boot prompt. Simply press Enter at this point.
Once you press Enter, you should see the message Loading..., and then Uncompressing Linux..., and then a screenful or so of information about the hardware in your system. In general, you can ignore these messages. Linux will look for various hardware devices and will tell you what it finds and doesn't find. Don't worry about messages at this point. Just wait until you see the Color Selection screen. If you have trouble, see section B.2 on page .
