Windows 7: How to set SATA configuration to AHCI

Not having re read the thread again, but windows has to be installed in AHCI mode. You can`t install in IDE then switch it, or copy over an image that was from a system set to IDE, that`s why the drive doesn`t boot after you switched it.

You`ll have to do a clean install, but first having AHCI enabled in the bios.

Thanks for your reply. Perhaps you missed it; 7Forums has a tutorial dedicated to the problem:
AHCI : Enable in Windows 7 after OS install
found here: AHCI : Enable in Windows 7 / Vista

I have carefully followed this tutorial, but still no luck.

Is this a UEFI BIOS? If so then you'll need Windows Boot Manager listed first to boot.

What happened when SSD is plugged into SATA1 with all other drives unplugged? Was waiting to hear.

Point is AHCI has to be enabled in the bios, first, before an install.

Regardless of what that says.

Or you are not doing it correctly.

UEFI BIOS: don't know what that is.
With SSD plugged into SATA1: Unable to see the SSD in the boot order. Unable to boot. Asks me to insert disk in optical drive.

Not sure what you mean. Is the tutorial I cited incorrect? Or am I not following it correctly?
The tutorial spells it out very clearly, and I followed all the steps.

I keep telling you, you enable AHCI in the bios but when you do the switch from IDE to AHCI, that`s why windows won`t boot. or the drive isn` seen etc.

Windows has to be installed in AHCI in order to run in AHCI.

You migrated a system that was installed in IDE mode, now you are trying to switch it AHCI, not gonna work.

I don't see UEFI in the specs for your Motherboard - P6TD Deluxe - ASUS.
More importantly there is no EFI System partition in your Disk Mgmt screenshot so that rules it out.

Your BIOS may require that you set the SSD as the Primary hard drive first before it will be the first HD to boot in BIOS setup. Is it listed as first to boot in Boot Order when plugged into another port?

I also notice there is a System file moved to another hard drive. Possibly if you turn off the paging file and then turn it back on for C following Change Virtual Memory Paging File this may stop whatever is blocking AHCI : Enable in Windows 7 / Vista as I can't remember it not working before. But having a system file on another drive does catch my attention as possible interference for making such a significant change without reinstall.

In other words, the tutorial I cited (AHCI : Enable in Windows 7 after OS install) is just plain wrong???

The SSD is listed in BIOS as first to boot in Boot Order--because I set it that way. Thereafter, when I switch to AHCI in the BIOS, the SSD does not appear at all in the Boot Order.

I assume you refer to "User" files (Pictures, Music, Videos) which I have moved to the E:\ drive after migrating the OS. This was the recommended procedure to make more room on the SSD.

How do I turn off the page file on C:\?
