I downloaded the four ISOs name FC4-test1-discX.iso. The SHA1 sum on each of these checked out fine, so I went ahead and burnt these to CDs. Upon booting from CD1 and running the mediacheck, the CD fails. I also attempted to run the mediacheck using VMWare, emulating the CD-ROM from the ISOs, upon which the mediacheck failed as well. When attempting to install, I can get all the way to the "Installing Packages" screen when I receive the message "An error occurred trying to format hda2. This problem is serious, and the install cannot continue. Press <enter> to reboot your system." Checking the logs shows that it is failing while attempting to format /. Any help?
