Just the other day, I stumbled upon a couple of challenges when trying to install Windows 7 on a RAID array of two SSDs on my computer.

1st Issue: The missing RAID drivers

Since they didn’t exist when Windows 7 SP1 was put together, I had to load them manually inside of Windows 7 Setup.

This was simple enough, though:

  • I got on my laptop and downloaded the Intel RAID drivers from the ASUS support page for my Sabertooth X79 motherboard, then extracted the files to a USB drive.
  • I unplugged the USB disk from my laptop and loaded the driver from within Windows 7 Setup by connecting the USB drive to my main computer while in the “Where do you want to install Windows?” screen. I clicked “Load Driver” and browsed to the “Driver\Disk\64bit” folder. The next screen let me choose which driver to install (only gave me one choice).
  • The driver loaded in a couple of minutes and the disk showed up, just like a good student to school.

2nd Issue: “Setup was unable to create a new system partition”

This issue was a little trickier. To my disappointment, Windows 7 wouldn’t let me install on the RAID disk array I had chosen, giving the following error message:

“Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information”.
