I ddnt really know how to forumulate the question for this isssue, so hopefully the body of this question will make my needs come clear. I have a legal coroporate copy of Wnidows 2008 server install. We are provided this by Microsoft in the form of ISO file per our Software Assurance contract. I burned the ISO to a Bootable DVD. I inserted the DVD into a machine that is set to boot on CD\DVD. The installation is going fine until I have to enter the corporate product key. I enter the key successfully, but after about five minutes, I get the message, "Windows installation has encountered an error and needs to be restarted" I khow I am using good media becuase I have used for DVD's already. My whole packaged of Blank DVDs cant be bad becuase I have used them for numerious other burns. The media from Microsoft is not bad, becasuse I notified them of the issue with the downloaded ISO and they assured me that no of thier other SA customers have problems downloading it. I did an check on the downloaded ISO everytime it was downloaded. So, in short, the media is good, the ISO is good, so what could be the problem. Could it be that all my machines are AMD cpus instead of INtel? Would that yield the error is question, or have I just doing something stupid and dont know it.
