If they're both SATA drives, then I'm sorry to say it, but I'm out of ideas... I've gone through everything that gave me trouble when I changed my system to use AHCI, and still no luck. Sorry about that..

And my apologies for not replying yesterday, I don't have internet at home, so I reply to posts while I'm at work.

I called the motherboard manufacturer. This board is a Gigabute GA-965P-DS3 Rev. 3.3 with an Intel chipset ICH8. They informed me there is no driver for this chipset to work with Windows 7. They said my board is so old they don't have one to even test a driver for this chipset if they had one.

Driver for a motherboard chipset? Now we are getting in to territory I know nothing about. For whatever reason the issues I was having causing me to want to go to AHCI have gone away. I am not comfortable not knowing why, but for now I will leave well enough alone.

I just wanted to write back to you guys to thank you for all the help and to let others know if they run in to the same thing.

Spent the last 12 hours or so preparing for the fresh install by moving pix, music, and videos to DVD (I know... I should get an external HDD - had bad experience so far though) - my old 4x DVD-R's burned at 3.9x and took about 15-20 min each - my other 16x DVD-R's did the job in 5 minutes, so I believe the SATA fix is operational

If you will have NO DATA on the HDD that you want to save have a look at this tutorial at the link below, it'll show you how to do a secure erase while you do a clean install; you're right enable AHCI in the BIOS first and you won't have to mess around with the registry at all; be sure and keep me informed.


This works for HDDs also.

SSD : Optimize for Windows Re-Installation
Forgot to ask... I will be using an upgrade disk only... will this still work, or does the install look for something left behind to work properly?

Hello Spidey1976.



As soon as you get to the "install" screen press shift+F10 to get to a command window.



Also have a look at the tutorial at the link below.

Ok, I did change the 3 keys - Msahci, IAstor, IAstorV 'start' value to 0, but after restarting and enabling the AHCI mode from BIOS, I still got the BSOD with 000007b error.
The system is Dell Latitude D830 laptop with ICH8M chipset.
Any ideas?

Hello shanouser, welcome to Seven Forums!




Why are you changing "the 3 keys - Msahci, IAstor, IAstorV 'start' value to 0" when this tutorial only asks to change the value of the "msahci" key and no other value, where did you get that information?

From here:
Error message when you start a Windows 7 or Windows Vista-based computer after you change the SATA mode of the boot drive: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"

Any ideas why AHCI can not be enabled using value = 0 for the MSAHCI and/or IASTOR keys in the registry?

Yes, put everything back to the original settings and change just change the value of the msahci key, doing a system restore to a point before you made the changes will restore the original values.
