cant turn on AHCI after windows 7 x64 instalation

Solution
You actually need to change the key in the registry for AHCI to 0:

Start regedit by typing it in the Start window search box and clicking it; Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlset/Services; click on msahci; in the right side field right click on "start" key and select Modify; in the value data field enter "0" and click "ok" then exit regedit; now restart and enter the bios and change the bios SATA mode to AHCI.
