Ubuntu :: Lucid Lynx 10.04 Live CD -- No Boot Menus

I just downloaded the Lucid Lynx 10.04 LTS Install CD for the desktop. I am concerned that I have downloaded the wrong ISO or that the CD that I burned is not behaving properly. Unlike all of the other Ubuntu "Live CDs", this one doesn't offer you a choice of what Ubuntu does at Boot-up. There's no menu that asks what you'd like to do. This CD doesn't give you choices like:

- Test Drive Ubuntu without making any changes to your computer
- Install Ubuntu
- Test CD for Errors
- Test Memory
- Boot from Hard Disk

Instead, this CD just boots right to a Gnome desktop. Normally this wouldn't be a problem, but it turns out the the CD is performing some actions behind my back that I don't like. All that I wanted to do was to check the CD for errors to make sure that it burned properly. I didn't want it installing on the system where I was doing the burning. Instead of giving me options at boot, the CD automatically loaded Gnome, and then proceeded to mount all of the drives on my system, and then attempted to establish connection to IP address 91.189.90.132. I didn't like that. Luckily my firewall is secure enough that it stopped this unauthorized outbound data traffic dead in its tracks. I used reverse DNS to look up the owner if IP address 91.189.90.132. Here's what I found:

Code:

http://whois.domaintools.com/91.189.90.132
IP Information for 91.189.90.132

Is this a Live CD, where you have some options about what to do at boot-up, or is this only an install CD? This information isn't clearly spelled out on the download page. this LiveCD taking control of my computer, mounting my drives, and then establishing contact with Canonical Ltd., without even giving me a menu option before doing so.
