Hi there, I have a MSI 990FXA-GD80 motherboard that I just recently purchased. As part of my upgrade I also got 2 Seagate 3TB drives to put into Raid 0 to function as my boot drive.
I'm unable to figure out how to get windows installed. I Setup the raid array under legacy mode to configure the array and then set it to start the array using the "UEFI driver". After that I set the boot priority so that it boots into the EFI shell. I selected my DVD-ROM drive that had the windows 7 x64 install disk and the BOOTX64.EFI file from the shell. From there I booted the install disk and used the amd raid driver from the msi motherboard page then followed the prompts until I got to unallocated space then hit next. At that point it just comes up saying it couldn't format the disk and gives an error code.
Everything in the manual for the motherboard points to it supporting booting from a GPT drive but I'm unable to get it to work.
Maybe it doesn't support booting while in raid?
Here are the system spec's
