About turn on AHCI for SSD
Finally, no matter which tool you select to move your system to SSD, change your disk mode from IDE to Advanced Host Controller Interface (AHCI) is an important step. However, if you change IDE to AHCI in Bios directly after installed OS, you will find you could not boot into your system. This is also another reason why peoples suggest reinstall OS. Do not worry; we could change something else in our “regedit” to avoid this problem.
1)Run the Registry Editor (regedit.exe)
2) Navigate to the location:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
3) Set the "Start" value to 0 (zero)
4) Restart computer go into the BIOS-> configuration->change the disk mode to "AHCI" (IDE is set as default commonly ) . Save the new BIOS configuration and restart so that Windows boots.
When Windows starts, it will detect the change, load new disk drivers, and does one more reboot to start up with them.
5) Install the latest driver of your motherboard.
Note: This method only works in Windows 7, Windows XP could not support.
If your CPU is based on AMD platform, you need to do another step, download the “AMD RAIDXpert” from AMD official website, then log in it and turn on NCQ mode. This is important.
If your CPU is based on Intel platform, you need no to do this, the NCQ mode is turned on autonomic when you change ide to ahci and install the latest driver of motherboard.
