I am running in AHCI mode now and want to switch to IDE. In your post you show:
and you set each to 1 but from what? Is it supposed to be 0 before?
In my system I have:
Msahci = 0
iaStorV = 3
PciIde = 3
I do not have a iaStor key at all.
Does anyone know why I do not have an iastor key or why when the others are turned off it is a 3 instead of a 1?
First of all, thanks for this small guide.
However, I am now encountering a bad problem.
I did all the registry changes as you proposed. I restarted and changed from AHCI to IDE in BIOS before Windows would load up again. Windows started and a box appeared listing IDE and ATA related stuff being installed. Then I restarted as it prompted me to. Then on next load: BSOD. It appeared to work fine at first, but then failed. One thing I noticed was that the "Start"-value in HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/PciIde was already set to 0 beforehand, so I just left it so. Did I do something wrong? And what should I do now? I have the option to perform a System Restore to god-knows-when. Damnit. ^^
EDIT: Error reads "BAD_POOL_CALLER", which usually indicates bad RAM. I believe something went wrong on the lowest level of hardware interaction lol.
EDIT2: Changing back to AHCI causes another bluescreen to appear even as the animated windows logo pops up and I cannot get the chance to read what it says at all, because it disappears too quickly.
EDIT3: System restore saved my butt. That means I can infinitely try to mess around with this till something works. Waiting for some input on what I should try/check. Thanks in advance.
EDIT4: Just set it to IDE and reinstalled Win7 completely and it set itself up correctly that way.

Worked perfectly. Just follow the tutorial and everything works fine. Good job.
This might be a great bump but I just wanted to tell OP that I too created this acc to thank you!
I wasnt able to install w7 without this tutorial! Thank you so much!
(when i used AHCI they asked for drivers n' stuff which I couldnt skip, which made me unable to go further)
EDIT: Reinstalling the ATI drivers fixed my problem. Maybe this is a good thing to do to uninstall video driver before switching of the disk because of the mess that happens with the hardware resources. But who could predict which resource will be in your case?

Not like I don't appreciate it but I had to share that on my Acer 5251 Windows 7 HP 64bit pre-installed with AHCI just took a direct change in the BIOS to IDE and upon reboot, two drivers were automatically downloaded/installed and I was prompted to restart.... all good.
have been looking for this info. so many tnx. i have a couple of questions, however. hope someone can enlighten me.
will this work on windows 7 x64? as my windows 7 machine has AHCI enabled, can i change back to using AHCI from IDE if i want to, when i want to? will i have to do anything to re-enable the AHCI settings? the reason i am asking is because i cant do a image of my sata lll hdd. i suspect it is because of the AHCI setting, but not sure.
That's funny, the whole reason I looked into switching to IDE was because of backup issues. Anyway, it did not help, so I switched back AHCI... no problems.
