Windows 7 - change storage controller to AHCI mode post install (win7 64-Ultimate)

Can someone hit me with a link for manually installing the AHCI driver and switching the OS mode for the storage controller.

If I remember right, this is just putting the driver in /sys/drivers, running a script, and making a registry change. Then you reboot, change the motherboard setting, and then install IMSM after the OS comes back up. I don't remember the script, or if it was just a reg edit, etc.

Thanks,

Normally this is done in your BIOS, once you have the driver downloaded and installed. When that is done, reboot, go in to bios change settings, save and exit and complete the reboot.

Windows won't let me install the driver because it can't find any AHCI devices enabled. If I change the bios to AHCI mode, windows won't boot because windows doesn't have the AHCI drivers installed.

This was a much bigger issue in XP where if you installed in IDE mode, then it was a pain to switch to AHCI or raid, since you didn't f6 install the 3rd party drivers along with windows. If you switched to AHCI or raid mode in the bios, the OS wouldn't boot because of the missing driver. Also, you couldn't install the driver in windows because the driver install software wouldn't detect any AHCI or raid devices. You would get an error like, system doesn't have the appropriate hardware configuration, and the IMSM couldn't configure without locating the hardware. There was a workaround that was similar to my first post. This was commonly used by folks who wanted to image over their OS to an SSD that needed AHCI or to a raid partition without a full re-install. I have not run into this issue with Windows 7 before.

It seems like technology has progress to a point where this should not be an issue, but it appears it still it. This was installed over a vista install that was installed in IDE mode, so that may be where the issue comes from.

I found this tutorial linked by Bare Foot Kid,AHCI : Enable in Windows 7 after OS install

This is what I was looking for. I will post back if this works, or doesn't.

AHCI : Enable in Windows 7 / Vista

That is what I used to set Windows to AHCI.

After that is all completed then you go into Bios and set it to AHCI.

I'm just confirming what you found.
I didn't see your question earlier.

Thanks for the confirmation. This is more or less what I remember from XP, but a bit simpler. I will post back after I have tried it.
