I have 2 Dell Inspirons 2200, I've installed F14 on in the past. Both laptops fail to initialize, I've verified media, and I'm able to boot the DVD on another system.
That's strange. Fedora 15 should run on those laptops without problems. Now the installer for Fedora 15 requires more memory than the Fedora 14 installer did (A little over 700mb, I believe) so if you are running less than that, then it could be your problem.
