How do I enable AHCI on an Omen 15

[A_Personns]

I recently reset my computer (deleted everything and reinstalled Windows 10 locally) and now when I open my laptop (after a minute  or so) it restarts and gives me a INACCESSIBLE_BOOT_DEVICE error. I saw some people had luck fixing it by enabling AHCI mode in the Advanced BIOS settings, but I can’t seem to find it on my Omen 15. All I’ve really done on it was install Steam, then it started resetting. Every time it turns on, it’s just a matter of time (after every reset) before it gives me the error again.

Hello @A_Personns 

Sorry to hear that you are having problems ... 

AHCI mode is default !

BIOS => System Configuration => Intel(R) Rapid Storage Technology

Select your drive:

Controller Type: AHCI ( this options is not editable, it's default )

Please report your results

best regards

I’ve noticed the problem only occurs if I’m connected to Wi-Fi. What could be the fix for the problem?

Updating the BIOS is recommended as standard maintenance of the computer. It can also help resolve the following issues:

• An available BIOS update resolves a specific issue or improves computer performance.
• The current BIOS does not support a hardware component or a Windows upgrade.
• HP Support recommends installing a specific BIOS update.

Hello @A_Personns 

! Please reinstall your system !

Use HP cloud recovery tool !

Follow the instructions below ...

I quote what user Paul_Tikkanen wrote, changed the text color so it is clearer for you: "

You can use the HP cloud recovery tool on another Windows PC running Windows 7 64 bit or newer to create a bootable USB recovery drive that will reinstall W10, the drivers and the software that originally came with the notebook.

Here is an info link for how to use the utility.  You will also need a 32 GB USB flash drive to create the recovery media with.

HP Consumer PCs - Using the HP Cloud Recovery Tool in Windows 11 and 10 | HP® Customer Support

You will need to supply the product number of the notebook to use the tool, so use this guide for how to find the product number of your notebook.

HP Notebook PCs - Finding your product name and number | HP® Customer Support

If you cannot find the product number, you can also use the Microsoft media creation tool to create a bootable W10 installation flash drive and clean install W10.  Make the 64-bit installation media.

Download Windows 10 (microsoft.com)

Boot from the installation media and when you get to the part of the installation that asks, 'Where do you want to install Windows,' delete every partition on the hard drive, leaving just one partition of unallocated space.

Click next and W10 will install.

Using the second method to install W10, will give you the most amount of net usable space after W10 has completed installing.

You will have to be diligent in making sure you do routine disk cleanups, and do not install a lot of programs.
