I know that a lot of people were asking about wether they should upgrade or install SL. So, when I put in the disk, it said to shutdown and restart so that it could install the OS. Anyways, I just wanted to know if it was normal that I didn't have any choices as to if I wanted to make just an upgrade or a complete installation of SL. I thought I was going to lose my stuff on my HD, but everything is still there like if nothing happened. The thing is... I kind of wanted to have everything erased and do a clean install.
