Fedora 15 - boot menu

[Ronda Strauch]

Hi, I'm trying to install Fedora 15 from a live CD, but the boot menu did
not appear so I could select "install a new system."  Upon booting, a
message came up that my system didn't support GNOME 3 so it fellback. But
then it continued to a blue screen with Applications and Places in a user
menu.  How do I get to an install window to load Fedora on the hard drive?
