Enable the AHCI driver

To fix this issue you need to enable the AHCI driver.
To do this, follow these steps:
(1) Start->Run->type regedit and then press enter.
Navigate to the following registry key:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci
In the right pane right-click Start in the Name column-> Click Modify->Type 0 in the Value data box->ok
(2) Exit
(3) Reboot your computer, go to BIOS and enable AHCI. Again restart your computer to finish the driver installation.
