Check if your downloaded iso had the correct md5sum or sha-1 sum (the md5sum will be different than the one posted in that tread of course):http://ultimatebootcd.com/forums/viewto ... =10&t=2492
If your ISO is corrupt, redownload it.
The fastest way is using the torrent. If you point the download location of the ISO to the ISO file you already downloaded, your torrent program will only download the parts (blocks) again which where corrupt and not the whole ISO. Using torrents for large files is always a good idea. Torrents use internal checksumming to ensure that the right data is downloaded, and it will automatically redownload the wrong blocks again.
