SATA AHCI not working - HELP!

post #1 of 19
Thread Starter 
Hello everyone I'm new to overlock.net.

As title mentioned that would like to ask how is it gonna set to AHCI.

I had Windows 7 Professional in my PC and now i would like to install Intel AHCI driver without reformat my PC.

So I did search here or google (http://www.overclock.net/t/1227636/how-to-change-sata-modes-after-windows-7-installation) that i had completed these steps which is,

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci - Change to AHCI mode from IDE mode

But when i boot with AHCI bios settings it still goes BSOD.

Anyone have solution?

Would appreciate it.

***Anyway, correct me if i'm wrong post section***

Thank you.

Hey, romano91! Welcome to Overclock.net (or "OCN")!

 

So, you changed the value of the subkey named "Start" to 0, rebooted into the BIOS, changed over to AHCI mode, and it's still gets a BSOD when starting up?

Hi TwoCables... smile.gif

Yup. And just now i found out that after i had changed the registry key and BIOS settings to AHCI, i was try to boot from a Windows 7 DVD.

After that it can't detect my bootsect if im not wrong because it doesnt shows any operating system.

What (or who) told you that you have to boot from a Windows 7 DVD? When making this change, it should just be a simple process of changing that subkey in the Registry to a value of '0' and then changing to AHCI mode in the BIOS.

What motherboard do you have? Usually you have to install the AHCI chipset driver to get it to work properly after switching the registry.

I know, I understand exactly what's happening, but you said that you found that you were supposed to boot from the Windows 7 DVD. Who or what told you to do that?

But Windows has a generic AHCI driver, msahci.sys.

Ok. Now im using IDE mode on my installed windows 7 Professional. Don't bother about the Windows DVD since im noob and may giving wrong info to you all.

So i did check my system32 it does have msahci.sys.

And i did the registry editor. After i booted still the same. So what is the problem.

Im using Gigabyte EP43-DS3L.

Ok go here and Download and install the "Intel SATA RAID/AHCI Driver" http://www.gigabyte.us/products/product-page.aspx?pid=2847#dl

Install it then switch the registry to AHCI, reboot, go to bios and switch it back from IDE to AHCI and it should boot without issues.
