If we enable AHCI at BIOS after Windows is installed without this option, Windows won't boot. Follow the steps to enable AHCI support after-the-fact: 1. Exit all Windows-based programs. 2. Start regedit.exe as Administrator. 3. If you receive the User Account Control dialog box, click Continue. 4. Locate following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci 5. In the right pane, right-click Start in the Name column, and then click Modify. 6. In the Value data box, type 0, and then click OK. 7. On the File menu, click Exit to close Registry Editor. 8. Reboot and enable AHCI under BIOS.
