:Is your kernel recognizing the SATA controller (dmesg)?  Are you
:using the same kernel on the hard disk as on the CD?

    The most common problem is with BIOSes which try to automatically
    recognize the operating system and then put the disk in a weird mode
    that prevents the OS from being able to access the disk.

    Go into your BIOS config and push into the hard drive config.  See
    if you can select the access mode for the hard drive.  e.g. 'auto',
    'large', 'lba', or 'cha'.  Try putting it in 'large' mode (if it has
    that selection), else 'lba' mode.
