My Toshiba Satellite p745 won't boot on ahci after i installed a win 7 home premium on compatibility for sata, so i could install the os.. It works fine on compatibility mode but it seems to slow and everytime i install a driver for the laptop it shows the blue screen(crashed?).. So when i turned it to ahci it just won't boot, it just shows the Toshiba splash screen, then a black screen for about 5 minute or more, and it will just reboots again.

You can't change the SATA mode after Windows has been installed. If you want to use AHCI mode you need to set it to AHCI and re-install Windows.

I did try to re-install it by AHCI mode, but the laptop won't allow any re-installation in AHCI mode.
