It is hanging on the "select the appropriate keyboard for the system" screen. When i select US English then Next it just freezes up. Any advice? Also when i did the check disc option it said the disc was missing checksums. I burnt it to a DVD-R using Nero. Did i miss something?

I see now that the "test disk" option should be skipped. It doesnt work. I unplugged my USB flash drive and its not hanging any more.
