 いちいちどのレジストリいじるべきか調べるのが面倒くさいから記録する。

まとめ

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride0にする。AHCIからIDEモードにするときに機能するかは不明である。

Yes there is a way on WIN 10 also ! Go into BIOS set the SATA mode to IDE and boot into system.

Start REGEDIT and look for this line :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride

Change the 0 DWORD value from 3 to 0.

Reboot, and change your SATA controller to AHCI in BIOS. Now let it boot into safe mode, WIN 10 will install required drivers for AHCI.

Now with a normal boot you will boot into Windows with AHCI drivers.

Note : OEMs suggest reinstalling rather than changing, especially with an SSD.

You stand the chance of loosing your install if something goes wrong, and different systems may behave differently.

Not Recommended for Windows 7.
