I have a Dell PowerEdge 2850 running Window Server 2003. I am required to upgrade this server to Windows Server 2008 R2 Standard Edition, in order to be able to backup my Exchange 2010 server, using Backup Exec. This server has a CD-ROM. I have downloaded an ISO image from eOpen.Microsoft. Using Roxio, I was able to split the image into 5 CDs. Each image is an ISO file. (Unfortunately, we no longer have a Systems Administrator, and I drew the short straw). Question 1.) Can I boot from a ISO or do I have to unpack it somehow before burning it to CD. If question 1 is yes, I can boot from the ISO on CDs then, Question 2.) How do I get the server to boot from it. The server does not prompt me to press the space bar to boot from CD, as it does for desktop and laptop computers.
