Installing virtual sbs 2011 on mac, first which disk do I install out of the 9

Hi, 

Wanting to install sbs 2011 on my mac and be able to have one be a test SBS and the other be a live SBS using VMware Fusion. 

When trying to install SBS disk I receive an error message "Operating system not found" 

Also, wondering which CD to install first and if this is the cause of the error message. 

Any assistance is much appreciated.
