Windows 8 Pro ~ SATA/AHCI

Hello,

Looking for some help, I obviously didn't do enough homework..!!
Hope this post is in the right place.?

I have installed Windows 8 Pro on a small new ASUS Intel H61 based mini PC.
Everything appears to be working fine.?
I had 1 "!" in the device manager that went after doing Windows Update.

The issue is the disk is showing IDE.? I did not set it to AHCI in BIOS, It is a SATA SSD Drive.
I've done a lot of searching here and elsewhere and found various registry change fixes...
But they are different.?

This one: IDE to AHCI
Goto:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride
Change the 0 DWORD value from 3 to 0.
Reboot, and change your SATA controller to AHCI in BIOS.
You will boot into Windows with AHCI drivers.

"will it prompt for drivers, which drivers or are they already in Windows 8 ?"
"Also are there SATA Drivers and AHCI Drivers, or is one in the same"

Then this one:
To Enable AHCI In Windows


1) Run the Registry Editor (regedit.exe)
2) Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
3) Set the "Start" value to 0 (zero)
4) Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Pciide
5) Set the "Start" value to 0 (zero)
6) Shut down
7) Start up again, but before Windows boots go into the BIOS configuration screens and change
the disk mode to "AHCI". Save the new BIOS configuration and restart so that Windows boots.
When Windows starts, it will detect the change, load the AHCI disk drivers, and do one more
reboot to start up with them

Problem.?
I don't have the KEY = HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci

Finally,
I found this: Error message occurs after you change the SATA mode of the boot drive but it's for Win7

Also, I don't have the KEY = HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci


Any help on this would be really appreciated.
BTW,
I missed out on the VISTA & Win7 releases, So it's all new to me.
I have a Win XP Pro machine, now built a new PC with Win 8 Pro.
Sorry for the long post..
Also I think I have learned more about Windows 8 on here in a couple of days... than any where else

Thanks... Dave

It should have been set to AHCI for the install. Rather than try to fix that after the fact, I would suggest a clean install as my preferred method of handling this issue. However, there have been some with reported success in changing the mode from IDE to AHCI after the fact but there also have been may reported failures as well. I say go for the clean install.

Welcome to EightForums.

First check your BIOS settings.

If I redo the install, with the BIOS set to AHCI will I have to provide SATA/AHCI drivers during install,
or are they in already on my Windows 8 install disk.?

Thanks - Dave

Welcome to EightForums.

First check your BIOS settings.

I did... After I noticed in Device Manager.
That's how I realised it was wrong... :(

If you change it in the BIOS "before" you attempt the 2nd clean install, it should work the second time around. Old operating system (like XP) did not contain SATA drivers by default and they had to be loaded at an f6 prompt or slipstreamed into the installation; however, Win 8 most certainly has the default SATA drivers you require so it should work.

This is Windows 8.0, I noticed in the set up link there is a step about Windows 8.1 "How should we set up your PC"
Will I get anything similar.? I have activated this install, so will doing a new install same machine create an issue.?
I want to give it same name etc...

Thanks... Dave

No, everything should be fine. Just make sure that you pay careful attention to step 7 in the next tutorial below. Note that the drive partitions were deleted until it was 100% unallocated. At that point, simply click NEXT. You will be asked many questions during this setup procedure and you will be able to use the same name and everything else again.

From the first tutorial you should be directed to this tutorial.

Yes,
I remember when I did the 1st install in advance getting rid of all partitions on Drive #0 (SSD) and Drive #1 Spinner.
I assume I will also have to remove the Hidden 350MB partition that Win 8 created it'self.

Thanks... Dave

YES, that would be required to get to 100% unallocated.

Fixed: SATA/AHCI vs IDE

Did a clean re-install with the BIOS SATA AHCI set, all is now fine.

I have a single entry in the Device Manager Controller: "Standard SATA AHCI Controller"

Thanks to all for comments
