P5B Deluxe SATA IDE to AHCI after Windows install

[imported_richardf]

Back in November I read a post from someone in the forums here that explained how to use AHCI SATA after installing Windows but I guess the archive monster has eaten it.

Anyway, as I remember it, it goes something like this:

1. Install Windows on boot drive attched to ICH8R in IDE mode
2. Install the JMicron SATA drivers from Windows
3. Switch boot drive connection from ICH8R to the JMicron controller
4. Go into BIOS and set ICH8R SATA to ACHI, set JMicron to IDE
5. Boot into Windows and install Intel Storage Matrix drivers for ICH8R
6. Switch boot drive back to ICH8R SATA connector
7. Boot to Windows

For some reason I get an error message "Error loading operating system" as I am trying to do step 5. It never gets to start booting Windows as far as I can see.

The odd thing is that I know this worked back in November. I am probably just missing something.

Anyone know how to pull this off?

Thanks!

The way I did it was set the controller to standard ide in the device manager installed the drivers then syspreped the system.
Went in the bios then changed it over and viola ahci installed.

I just did this.

1) Enable the JMicron controller in the BIOS and install JMicron drivers. Shut down.
2) Connect boot drive to JMicron controller, go into BIOS, change Intel SATA to AHCI. Make sure the JMicron controller is the boot device. I disconnected all other SATA drives at this point.
3) Install Intel drivers. Shut down.
4) Reconnect boot drive to Intel controller
5) Profit!
