I've had a bunch of issues with my Fedora 14 -> 15 upgrade, and I have burned two DVDs and apparently for no reason. I can't install Fedora 15 from scratch. I've tried with basic video plus the standard installation method and I keep running into the following issue:

Here's the thing:
1. I've unchecked gnome-bluetooth as an option. Why is this still happening?
2. The installation media has been verified both by the DVD-burning app and repeatedly when I first boot up. There's nothing wrong with it which is why I burned TWO DVDs to be safe.
3. In one instance, I disabled the installation repo and had tried to do this purely over a networked connection.

So... what next? Go back to Fedora 14?! This is ridiculous

Not solved, but I downgraded to Fedora 14 so I'm not having this issue anymore

I'm a complete newbie with Fedora. I'm even about to search on how to use the package manager from the command line (and maybe the hidden shortcuts in GNOME 3). I installed it from the live-CD (only English included).
The same ISO when I tried to install using a USB flashdrive didn't work (the installer kept filling up the whole partition).
