injecting RAID drivers

I have an OS that was installed to an SSD in AHCI mode. I made backup of that OS. Now I want to restore that OS to a RAID-0 array. My restoration software has the ability to make a usb boot stick with the raid drivers. So when i boot into that restore environment, it sees my freshly formatted RAID-0 array as well as my hd with the image I want to restore. I can proceed with the restore but the image itself does not have RAID drivers. If I try to boot from that newly installed system, it will choke when it sees a RAID-0 but is expecting an AHCI. How do I inject the raid drivers into that boot sequence?

Once booted, I can formally install the drivers (Intel RSTe) into my OS (Win7 PRO SP1)
 
OS may already "know" that RAID device, more so if you installed intel drivers on top of generic ones. So there's pretty good chance that it will work without you needing to do anything.
 
You may just have to do another backup if it doesn't 'just work'.

Restore to a single drive in AHCI mode, install the drivers, then capture another backup. Then restore that backup to the array.

IMHO, it would be much simpler to temporarily boot the backup disk image and make a small registry edit that will enable RAID. When that's done restart the PC, verify that BIOS is set to SATA/RAID, then shut down and disconnect the drive. After the backup disk image is copied to the array; the first time that you boot the array Windows will be in RAID mode. One more reboot completes the MS RAID driver installation, and then you can reinstall the Intel RSTe driver and software.

Switch Windows from AHCI to RAID

Exit all other Windows-based programs then open regedit and locate the following subkeys:
Code: 
.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStorV
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStor
  • In the right-hand pane, right-click Start in the Name column, and then click Modify.

  • In the Value data box, type 0 (3 is default), and then click OK.

  • On the File menu, click Exit to close Registry Editor.

  • Restart your computer and *IMMEDIATELY enter the UEFI/BIOS setup.

  • Enable SATA/RAID mode, then save and exit to reboot the PC (or in your case; shut down and disconnect the drive until you're ready to copy it to the array).

*Keep in mind that should you inadvertently boot back into Windows, without switching to SATA/RAID mode in the BIOS, you'll have to repeat this from the beginning.
