Switch AHCI TO IDE

Welcome, I installed Windows 7 with AHCI set from Bios ,but i wanted to use ide mode again because it boots faster and when i set Ide from Bios ,the windows 7 loading screen came up and BSOD (Blue screen of death) with an error code 0x0000005B , i tried the regedit trick by setting in the "HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci" and then in the right pan the START value from 0 i set it to 1 and it supposed to be working but it was a failure, it still did the BSOD.

Here are the pases:
1) I assume you have installed Windows Vista or Windows 7 with AHCI set from BIOS
2) Download my registry fix and simply apply the key, link below.
3) Now the manually regedit part Go to :

HKEY_LOCAL_MACHINE_System_CurrentControlSet_Services_Msahci
HKEY_LOCAL_MACHINE_System_CurrentControlSet_Services_iaStor
HKEY_LOCAL_MACHINE_System_CurrentControlSet_Services_iaStorV

And in these three keys in the right pan you will find a key named "START" change all three (Msahci,iaStor,iaStorV) values from 0 To 1
Now navigate to
HKEY_LOCAL_MACHINE_System_CurrentControlSet_Services_PciIde
,then change the start value to "0"

Restart your computer, and go to Bios and set from AHCI to IDE, save settings in Bios and restart

Windows will be loading , No more BSOD, windows Vista/Seven will install new Ide drivers andyouu will see in windows device manager that you dont have AHCI drivers anymore and it will prompt for another restart , just restart it.

REGEdit
