Changing from AHCI to RAID

[Tom_Sand]

Needed to change a computer from AHCI to RAID after already installing windows and apps (Needed RAID For D: Drive not C: ) and stumbled across this :

1. Exit all Windows-based programs.
2. Press [Win] + R or take the RUN option from the start menu.
3. Now type regedit there and press Enter Key to open up the Registry Editor Window.
4. If you receive the User Account Control dialog box, click Continue.
5. Locate and then click the following registry subkeys:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStorV
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStor
6. In the right pane, right-click Start in the Name column, and then click Modify.
7. In the Value data box, type 0 [3 is default], and then click OK.
8. On the File menu, click Exit to close Registry Editor.
9. Restart your computer
10. Go to UEFI/BIOS and enable RAID, Save & Reboot
11. Another restart will be required to finish the driver installation.

Obviously not ideal but seems to be working fine but I have backups just to be safe.

Hopefully it will help someone else out in the future.
