I had the same exact problem and its not the media. I had 2 servers. 1 fianlly loaded on the 3rd try the second loaded on the 9th or 10th. On the one that took 9 or 10 we switched the locations of the 2 hard drives and that was the time it finally loaded. I had to come back and rebuild one of these servers later because of a RAM failure and never had an issue getting os to load. So its like once you get it to load it works from then on. Also I noticed when they did not load, during the bootup it would say bios not installed but when the load was finally sucessful it would say bios loaded or something like that. So I think it has something to do with bios.
