- In the right pane of the storahci key, double click/tap on the Start DWORD to modify it. (see screenshot above) 11. Type 0 (zero) for AHCI, and click/tap on OK. In the left pane of Registry Editor, browse to the key location below to see if you have the StartOverride here.
- Jun 12, 2019 Before you start: you need to have Administrator access level to enable AHCI in Windows 10. CAUTION: follow this manual carefully to prevent being stuck in a boot loop and data loss.We have tested this manual on our own systems, and we can confirm it works. But as we told you before, the best way to enable AHCI is to do it from BIOS with clean Windows installation.
Do you mean in device manager? Cause it has a collaspse menu that says IDE ATA/ATAPI controllers. Then when i click that menu to expand - it shows ATA Channel 0 - ATA Channel 0 - ATA Channel 1 - ATA Channel 1 - Standard Dual Channel PCI IDE Controller - Standard Dual Channel PCI IDE Controller (Note the ' - ' sign means its a new line in the expanded menu).

Should I Enable Ahci Mode
How to enable AHCI support for Windows on an iMac, MacBook or etc
Apple does all the dirty tricks to show the iSheeps that Apple is a superior brand and provides superior performance compared to competition, the last one I found is that it disables AHCI support for Windows on its hardware. By disabling AHCI (which you have already paid for it and Apple hardware has this feature) it forces Windows to use ATA controller disk drivers which is considerably slower than AHCI and has less features. for example you wont have TRIM support on your SSD disk on your Windows.
By doing so, Apple gives you this feeling that Windows is slower than Mac OSX on the same hardware.
Hopefully there is a workaround for this fraud of Apple. You will need to modify the Master Boot Record of your Windows drive.
This workaround only works for Macs with Intel disk controllers. If you have Nvidia chipset, it will not work for you. You may confirm it in device manager of Windows.
First step is to make sure windows tries to load AHCI drivers after AHCI is enabled in boot loader. if you miss this step you will get a BSOD on booting windows and you will need to restore old MBR for windows too boot up.
Open your Windows registry editor and make sure “Start” Value in the following keys are set to 0.

Also we need the modified MBR which you can download from here : patchedcode.bin
Put the patchedcode.bin on a USB stick which we can use later.
OK, We are done in Windows. Now we need to boot using a Linux Live CD or MacOSX Install Disk. both will work.
Put the bootable CD or USB stick into your computer and reboot.
When you hear the boot sound (the white screen appears) hold down the option (alt) key. you should get the option to boot from CD or USB stick.
Boot from CD or USB stick and Open a Terminal Window.
First lets get a backup from current MBR so in case of any problems we can roll back to it.
Also please note I am assuming your windows disk is /dev/disk0. if yours is different you may need to change it.
Put in your USB stick, change directory to it and run the following command :

How To Enable Ahci In Bios
Harmony sovereign guitar. In Windows you should see windows installs the new AHCI drivers. also you may check that by looking into device manager.
Also I recommend you to download and install “Intel Matrix Storage Manager” to update your AHCI drivers to intel’s ones.
If anything goes wrong, you can revert back to old MBR by following commands in Terminal :
