Windows 7 /Windows 8 crash after change BIOS SATA mode setting from IDE to AHCI

將 BIOS 的 sata mode 由 IDE 改為 AHCI 後, Windows 7 / Windows 8 就開不能開機了

I installed Windows 8 on SSD and forgot to change the SATA mode to AHCI in BIOS. So the score of AS SSD benchmark is not good:

"pciide - BAD" means the SATA mode is set to IDE in BIOS.

If you don't want to re-install Windows 7 / Windows 8, and just change the SATA mode from IDE to AHCI in BIOS, then it will crash (BSOD).

You have to change the registry setting first:

In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride, change the setting of key setting of "0" from 3 to 0.

Then change the SATA mode setting from IDE to AHCI:

After reboot, Windows 7 / Windows 8 will not crash and the score of AS SSD benchmark is good:
