Hi,
If you want to add the last Intel AHCI driver to Windows 7 PE disk, this article will introduce how to use DISM command and other commands to make your thought come true. Steps to add last Intel AHCI driver to Windows 7 PE disk: 1. Download the latest Intel AHCI Driver in the following link, and unzip it to a folder. Yes, Windows 7 has the necessary AHCI and raid drivers available during install. I Installed windows 7 successfully on a SSD when the sata mode was set to AHCI. As to raid support of the ICHR10 chipset, I believe the support is there, but since I have no use for raid, I cannot personally verify that option. The normal ICHR10 support is there. But I had already installed Windows 7 SP1 and a bunch of other updates that took a long time, so I didn’t want to use this nuclear option unless it was absolutely necessary. Luckily, after much research, I found a procedure that allowed me to install the SATA AHCI drivers without reinstalling Windows 7.

Thank you for posting your query on Microsoft Community.
AHCI (Advanced Host controller) makes NCQ (Native Command Queing) along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible; Vista was the first to offer this feature. The issue with AHCI is it needs to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC. The reason why Windows disables the AHCI drivers not needed during installation.
I would suggest you to enable AHCI after you have installed the OS if you didn't already have AHCI enable in the BIOS when you installed the OS.
