===== BIOS Setup =====
  * Make sure the BIOS is set to AHCI rather than IDE as SATA disk controller mode before installing Windows.
  * If Windows was installed with IDE setting, you must follow the following steps to change it to AHCI. Failure to do so will make your Windows installation non bootable.
    -  Right-click the Windows Start Menu. Choose Command Prompt (Admin). If Windows PowerShell is installed on your system, open a Windows PowerShell (Admin) window, and then enter "cmd" to ope a Command Prompt. bcdedit does not work within the PowerShell.
    - Type this command and press ENTER: bcdedit /set {current} safeboot minimal
    - Restart the computer and enter BIOS Setup (the key to press varies between systems).
    - Change the SATA Operation mode to AHCI from either IDE or RAID (again, the language varies).
    - Save changes and exit Setup and Windows will automatically boot to Safe Mode.
    - Right-click the Windows Start Menu once more. Choose Command Prompt (Admin), according to Step 1.
    - Type this command and press ENTER: bcdedit /deletevalue {current} safeboot
    - Reboot once more and Windows will automatically start with AHCI drivers enabled.
    - You can check that the AHCI drivers are active by navigating to **Control Panel -> Device Manager -> IDE ATA/ATAPI Controller**.
