Windows 7 Windows 7 Installation Fails with Error: 'Windows Could Not Complete the Installation'

Just guessing but it's possible that your install is having trouble with the onboard Marvell or Intel based raid you can go here http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%c2%ae+975X+Express+Chipset+Boards&ProductProduct=Intel%c2%ae+Desktop+Board+D975XBX2 and incorporate the appropriate drivers into your install or perhaps take a look at the motherboard bios screen and see if you can change the behavior of the controller to imulate something else, like plain jane SATA, or something else....take a look at your options and see if that helps, if you have problems maybe let us know what the potential options are and we can make a recommendation.
