ahci

I had my drive controller configured for IDE when I installed Windows 7. This didn't change when I upgraded to Windows 8.

I now need to enable AHCI, but doing so causes Windows to fail to start. It doesn't know how to automatically fix the problem.

I was able to use Regedit from the recovery area, in order to try using this fix that worked for Vista. That key is missing in Windows 8, however.

I read that the relevant key is now in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci. But my settings already match the changes they suggest making.

How can I get Windows to boot after enabling AHCI in the BIOS?
