Acer Nitro AN515-57 IRST driver not detected during Windows 11 clean Install

CarloLaggui

Hi guys!

Need your help. I recently clean installed w11 for my Nitro, apparently Ive searched all over the internet about its recognition on my m.2 ssds. I Landed on a video that discussed on turning the VMD on bios and my OS installation came in to success. After installing all drivers, FPS on my games(dota 2, NBA 2k25) dropped 10-30 fps average so I came tp google again to research about it. Now, I want to reinstall a clean windows 11 again and perform a IRST driver Installation upon OS installation.

I came across on many videos that instructs to download thr RST file on Acer web and intel web. Then tells to extract it and paste into the bootable pen drive. My problem now is neither of the 2 drivers downloaded from both sites are working. It keeps on telling me that driver isnt installed.

Any advice you can give guys, BTW, I used CMD to extract the RST files. Thanks!

To fix the Acer Nitro AN515-57's hard drive not being detected during a Windows 11 clean install, you need to download the correct Intel Rapid Storage Technology (IRST) driver from the Acer website, extract it to a USB flash drive, and then use the "Load driver" option on the Windows installation screen to install it from the USB drive. After loading the driver, the hard drive should appear, allowing you to proceed with the Windows 11 installation.

Step-by-Step Guide:
Download the IRST Driver:
Go to the official Acer support website and enter your laptop's model or serial number.
Locate and download the latest Intel® Rapid Storage Technology (IRST) driver for your specific model and Windows 11.
Prepare the USB Drive:
Extract the downloaded IRST driver files to a folder on your Windows 11 installation USB drive or a separate external USB drive.
Load the Driver During Installation:
When you reach the Windows 11 installation screen and select "Where do you want to install Windows?", click on the "Load driver" option.
Click the "Browse" button and navigate to the folder containing the extracted IRST driver on your USB drive.
Select the appropriate driver (it might be named something like "Intel RST VMD Controller") and click "Next" to install it.
Continue the Installation:
Once the driver is installed, your storage drives, including the M.2 SSD, should be recognized.
You can now select your drive and continue with the Windows 11 clean installation.
