It means you have automatic login set up. Take a quick screen shot of system preferences users screen and let's see what is already there. Based on that I can make a more specific recommendation. Do you know your password (even if you never have to enter it?) Of course no need to post usernames or passwords here but I just want to make sure 1) your account is an admin account and 2) you know your own admin password. I'd hate to do something hasty that causes you to get locked out of your Mac. Even if you already have other user accounts on your Mac, I'd like you to make a brand new one so we know that a SL install disk gets spit out regardless of what user is logged in at the time.
BTW, before we go any further, do you get an error when the disk gets spit out? I would go to Applications/Utilities and run Console. With console running and visible on the screen, pop in your SL disk and wait for it to spit out. Watch what shows up in console (text) when the disk is being spit out.
Hi Again....When I went to console thing there was a lot of text which I will add here, this was before I tried to put snow leopard in to see what was coming up, when I just put in snow leopard nothing came up on screen, it just popped out after a few seconds. Whats puzzling me if I put in a cd it goes straight to itunes and shows tracks and asks if I wish to add to library, football manager straight in no prob everything works? here is what was on console before I put in snow leopard that last time.............Mac OS X Version 10.4.11 (Build 8S2167)
