I just rebuillt my media workstation with a Gigabyte EG45M-UD2H motherboard replacing an Asus P5W DH Deluxe (RAID failure). I built a 4 drive array configured in RAID 5. I've created a 500 GB partition to install the OS (64 bit Vista Ultimate), but so far have been unsuccessful. I've tried the fixes offered by MS (Article ID: 925481 for example) but no luck. All drive space has been allocated, formated, and initialized. The BIOS appears to be configured correctly, but as this is a new system I may be overlooking something.
Error messages received: "Windows is unable to find a system volume that meets its criteria for installation" and "The computer's hardware may not support booting to this disk..."
NOTE: When I turn off RAID functionality Vista loads fine; so it appears that the RAID does not look like a bootable device to Vista.
