Server Help

[Bob]

Hello, 
I have recently gotten the server addition of software. I had been using the evaluation copy of Microsoft home server. The evaluation time has expired. I was just playing with it until I found Ubuntu. I have tried to install the new software on the pc converted server, I get to the splash screen with options to install. When choosing install I get an error reading "this kernel requires an x86-64 cpu, but only detected an i686 cpu. unable to boot please use a kernel appropriate for your cpu".  I'm not completely computer illiterate but I have no idea where to go from here. 

Thanks for any help. 

Bob
