Description of problem: I have a Dell Dimension 5100 which is running F7 quite happily. I downloaded and burnt an F8 DVD ISO to upgrade it to F8. I can boot the DVD and get the installation menu. However when I choose the Install/Upgrade option, the boot into Linux fails. I see the "Loading vmlinuz..." and "Loading initrd.img..." messages followed by a "Ready." message. But at that point the installation hangs. Steps to Reproduce: 1. Insert installation DVD 2. Boot system 3. Select Install/Upgrade option Actual results: System hangs after displaying "Ready." Expected results: System boots into upgrade application. Additional info: Thought it might be a problem with my DVD burner, but I get exactly the same results booting from a Fedora boot disk from a magazine. Booting a Ubuntu installation disk works fine.
adding "edd=skipmbr" seems to be a usable workaround.
