    new Win 7 install enable AHCI - Missing operating system


    I've had some problems with drivers after installing Win 7. Got all that fixed and had a problem getting the pc switched on. Changed WOL settings and it seemed better, but I was getting a checksum error.

    I then found this thread-
    AHCI : Enable in Windows 7 / Vista

    I followed instructions, but now after restarting it is a black screen and stuck with-

    LOADING OPERATING SYSTEM...
    MISSING OPERATING SYSTEM

    By pure chance I hit F12 to see if I could get SAFE MODE but it came up with option to boot from CD / HD etc.

    I chose HD and then it gave me options from USB3 or something with a long sequence of numbers. I guessed that was my hard drive. It now started Windows.

    I guess that is the boot sequence?
