Installing Hardware RAID on Windows 7

Like a lot of Windows fans I pre-ordered Windows 7 and built a new PC ready to install it on; I chose a motherboard (MSI DKA790GX) that, like many on the market, has a hardware RAID controller on-board allowing you to take advantage of redundancy with RAID 1 and/or benefit from faster disk access with RAID 0.  Read more about RAID.

I had already installed Windows 7 before I remembered I wanted to set-up a RAID 1 array.  I tried to get the RAID array working with Windows already installed but soon realised I would have to set it up prior to installing Windows 7 because Windows kept hanging on boot-up because it was lacking the RAID controller drivers.

The supplied manual doesn’t explain how to get RAID up and running unfortunately.

RAID Controller Set-up

So here’s a quick guide to installing hardware RAID on a motherboard that features a RAID controller.  These steps assume you are performing a clean Windows 7 install rather than an upgrade, and they might differ depending on your system set-up, but the general principles should be the same.

  1. Download the RAID drivers for your motherboard from the manufacturer’s website and save them to a memory stick.
  2. Back up all your important data!
  3. Turn your PC off and unplug it.
  4. Install 2 hard disks preferably with identically capacity into your PC.
  5. Turn on your PC, press the delete key or F2 key when prompted to get to the BIOS menu.
  6. Find the option to select the RAID mode, save your settings and exit BIOS.BIOS RAID options
  7. On reboot you should see a new menu option to enter the RAID controller settings.  Enter the key combination when prompted to get to the RAID controller menu. AMD RAID controller menu
  8. Create a new RAID array selecting either RAID 0, or RAID 1.
  9. Select the disks that will form the array, save the settings and exit.
  10. On reboot press the delete key or F2 key when prompted to get to the BIOS menu.
  11. Check the boot sequence of your PC and ensure your optical drive is top of the list.BIOS boot sequence options
  12. Insert your Windows 7 disk into the optical drive and exit the BIOS.
  13. On reboot press any key when prompted to boot from the optical drive.
  14. Windows 7 should start installing.
  15. Select your localisation settings and click next.Windows 7 localization menu
  16. Click “repair your computer” and click the ”load drivers” button.Windows 7 install menu Windows 7 load drivers menu
  17. Insert your memory stick and browse to the correct driver and install.
  18. Exit back to the Windows 7 install menu click “Install now” and on the next screen click “Custom (advanced)” to perform a clean install.install-windows-custom
  19. When you are asked where you want to install Windows 7 you should see that the 2 RAID hard disks are now visible as just 1 drive.
  20. Add a partition to the new drive so Windows with be able to recognise it.
  21. Continue installing Windows as normal.
