I have another Dell poweredge 620 server. On that machine also I had installed VMWare ESXi but it expired after 60 days. Now when i am trying to do a fresh install from the VERY same cd rom....I get the same error. I guess VMWare once expired does not allow another fresh install of VMWare to proceed. Or maybe it has got something to do with the way I configured the RAID controller.
Currently i cannot see any hard drives when i try to install Windows server 2008 R2.
