I have VISTA Ult (64) installed on a system with 2 raptor hard drives raid 1 with the OS and 2 500GB hard drives raid 1 for data. I can't access VISTA and the startup repair can't fix the problem. I tried to upgrade to Win 7 Ult (64) RTM and received the message stating I had to boot into VISTA to upgrade to Win 7. Since I can't boot into VISTA, I decided to do a clean install of Win 7. During the install I supplied the raid driver and the install displayed all of the disks/partitions attached. When I selected the disk with VISTA installed, it stated 'Windows can not be installed to this disk. This computers hardware may not support booting to this disk. Ensure that the disks controller is enabled in the computers BIOS menu.' What gives???
