Windows 10: Enable AHCI in Windows 8 and Windows 10 after Installation

Could be corruption, or some issue with the driver or hard drive itself. Possibly even BIOS getting reset back to default settings using IDE with Windows still set to AHCI if a dead CMOS battery.

 

When I upgraded to W10 last year, I made one change to my desktop. Installing an SSD drive as my primary drive, with an IDE drive as secondary. I wasn't aware of changing BISO to AHCI until sometime after. Since that time I've followed a couple of directions how to take advantage of AHCI in the BIOS thru registry or Safeboot options. But each time I make the change, and after a few days or week, my desktop grinds to a halt. It takes time just to reboot it, and when I do, changing BISO back to IDE fixes the problem.

I can only surmise that installing W10 from scratch, with AHCI active in BIOS, might finally fix the issue.

Any other suggestions are welcome. Thx.

 

Mixing IDE and SATA drives is the problem. It's best to only have SATA connected.

 

Thanks. I updated the SSD driver via Intel's utility when I installed the drive. It was previously used as an external backup drive with no issues.
Think flashing the BISO to make sure its current/not corrupted would be a positive step? Maybe also reset CMOS and replace the battery? I haven't seen any issues with respect to CMOS.

 

Usually the only way to sort that is to only have the SATA drive connected, and remove all IDE drives.

 

OK. I'll see if I can connect drives just via SATA. Thanks for the help.

 

You're welcome. Please let us know how it went. *Smile

 

Worked perfectly. Thank you!

 

I'm glad it could help Davis, and welcome to Ten Forums. *Smile

 

Confirmed this "automatic" method: Solved Attn. SSD owners - Enabling AHCI mode AFTER Windows 10 installation. - Windows 10 Forums to work for my ASUS G752VY to switch from RAID to AHCI.

 

This has worked ok for me on Win 10 , I left Raid on in the Bios after removing the Raid Array and installing Win10 , the difference is you only need to change the Start Overide Registry Entries to 0 ( from 3) as the other two are already 0 under Raid , on reboot after switching to AHCI in the Bios, the Controller was using the Microsoft AHCI Driver , after which I changed it to the Intel AHCI Driver. I did it manually as I already had the extracted Driver in a folder for my ICH10R Controller. I would assume you could run the normal WHQL Driver installer too.

 

Thank you for confirming. *Smile

 

I've got only 2 questions to ask before trying this method and any help would be appreciated.

First of all can i use my SDD with AHCI while i use my HDD with IDE? And second question is i have Storahci registery but i dont have İastorv, would that be a problem while procceding with the method?

 

Hello Umut, *Smile

I'm afraid that you cannot use AHCI while having an IDE HDD connected. Doing so would cause issues with the HDD.

 

Thank you for quick reply but i'm planing to buy another SSD to replace my HDD so my second question still stands.

After i get a new SSD will i still be able to use this method with having Storahci registery but not having IastorV?
