    Windows 7...>SSD....Enable AHCI B4 Installation


    Okay I plan on doing a clean install of Windows 7 on my laptop. I have an SSD from crucial.

    I know that I need to enable AHCI BEFORE I start the installation of Windows 7...correct?

    Now....I saw this Intel website in regards to AHCI.
    Intel® Rapid Storage Technology — Configure the BIOS for RAID or AHCI on an Intel® Desktop Board

    I know that my laptop has a chipset that supports AHCI.

    But I'm worried about the whole...
    "Enabling AHCI or RAID after installing the operating system is not recommended or supported when a SATA hard drive is the boot drive. Enabling AHCI or RAID after installing the operating system might cause an immediate blue screen with an 0x0000007b error code, followed by a reboot. If you use AHCI or RAID, enable them before installing the operating system."

    SO my question is this....it looks like enabling AHCI is the absolute last thing I should do before installing Windows 7. As in this is the routine I should follow.

    1) Back up any drivers/files/etc that I need
    2) Insert Windows 7 Installation Disc
    3) Close out of pop up install window.
    4) Restart Laptop
    5) As laptop is restarting enter BIOS
    6) Follow Intel's step by step guide for enabling AHCI
    7) Change system to "Boot from DVD Drive"
    8) SAVE new BIOS Settings....EXIT

    At that point my computer should REBOOT and this time it will do so from the DVD drive and Windows 7 installation screen will appear correct?

    After that I should have no problems?

    OR am I missing something? Do I need to do anything in Windows 7 itself before I do anything with the BIOS?

    I've done it the other way before as far as a clean install of windows 7.....

    but that's not my main concern. However it looks like I found the answer on another forum....apparently there are 2 separate steps. I just wish someone could confirm it.
