SSD Driver Not Found Error during Windows 10 Installation on Acer Nitro N50-620

The SSD driver not found error during Windows 10 installation on the Acer Nitro N50-620 is typically caused by missing Intel RST (Rapid Storage Technology) drivers. This occurs because modern NVMe drives require specific storage controllers that are not included in the standard Windows installer image. By loading these drivers via a USB flash drive or modifying the BIOS settings, you can resolve the issue and proceed with a clean installation without data loss.

Understanding the Root Cause

When you boot from a Windows 10 installation media and reach the screen asking where to install Windows, seeing no drives listed is a common frustration. The Acer Nitro N50-620 utilizes high-speed NVMe SSDs that operate under different controller standards than older SATA drives. Specifically, many of these systems use Intel Chipsets configured in RAID or Intel RST mode by default. The generic Windows installer does not include the proprietary drivers needed to communicate with this specific storage controller, resulting in the "No Drives Found" message. It is important to note that this is not a hardware failure; your SSD is functioning correctly, but the software installer lacks the necessary bridge to access it.

Solution 1: Loading Intel RST Drivers During Installation

The most reliable method to fix this issue is to manually provide the correct driver to the Windows installer. You will need access to another working computer and a USB flash drive for this process. First, visit the official Acer support website or the Intel download center to locate the Intel Rapid Storage Technology (IRST) driver. Ensure you download the version compatible with your specific motherboard chipset, as the N50-620 often uses recent Intel processors. Once downloaded, extract the contents of the driver package to a folder on your USB drive. Do not simply copy the setup executable; you need the actual .inf, .sys, and .cat files contained within the extracted folder. Return to the Acer Nitro where the installation is stuck. Click the "Load Driver" button located in the bottom left corner of the drive selection window. Navigate to your USB drive and select the folder containing the extracted IRST files. After selecting the folder, click Next. The installer should scan the directory and display a list of available storage drivers. Select the appropriate NVMe or RAID driver and click Next. Your SSD should now appear in the list of available drives. If it does not, try refreshing the view or ensuring the correct driver version was selected.

Solution 2: Changing BIOS Storage Mode

If you prefer not to deal with external drivers, you can change how the system interacts with the SSD through the BIOS settings. Restart the computer and repeatedly press the F2 key to enter the BIOS menu. Navigate to the Main or Configuration tab using the arrow keys. Look for an option labeled "SATA Mode," "Storage Mode," or "VMD Controller." If it is set to "RAID" or "Intel RST," change it to "AHCI." AHCI is the standard protocol that Windows includes native drivers for, allowing the installer to detect the drive immediately. Save your changes and exit the BIOS. Reboot from the installation media again. While this method is quicker, be aware that switching from RAID to AHCI on an existing Windows installation can cause boot failures, so this solution is best suited for fresh installations on empty drives.

Solution 3: Using Third-Party Toolkits

In cases where official drivers are difficult to source, community-created toolkits can simplify the process. Tools like Rufus can create bootable USB drives that automatically inject necessary storage drivers into the Windows installation media. When using Rufus, select your ISO file and choose the target device. In the additional options section, look for checkboxes related to "Intel RST" or "NVMe" drivers. Enabling these options modifies the boot image to include the required drivers before they are even needed by the installer. This approach eliminates the manual step of loading drivers during the setup phase. However, always verify the integrity of any third-party tools and ensure they are downloaded from reputable sources to avoid security risks.

Post-Installation Steps

Once Windows is successfully installed, it is crucial to restore optimal performance if you switched to AHCI mode or used the driver injection method. If you changed the BIOS setting to AHCI, ensure that Intel Optane Memory or other caching features are reconfigured if applicable. Additionally, install the latest chipset drivers from the Acer support page to ensure full compatibility with the system's components. Without these updates, you may experience reduced SSD speeds or instability. Regularly updating the BIOS firmware can also prevent future detection issues, as manufacturers often refine storage controller support in newer versions.

Frequently Asked Questions

Will changing SATA mode to AHCI delete my data?

Changing the SATA mode from RAID to AHCI in the BIOS does not erase data on the drive itself. However, if you have an existing Windows installation configured for RAID, switching modes will prevent Windows from booting, requiring a reinstall. This risk only applies to existing OS installations, not fresh installs on empty drives.

Why does my SSD show up after loading the driver but then disappear?

This usually happens if the wrong driver version is selected or if the USB port used for the driver source is unstable. Try using a USB 2.0 port for loading the driver, as some USB 3.0 controllers lack native support in the pre-install environment. Also, double-check that the driver matches your exact CPU generation.

Can I use Windows 11 instead of Windows 10?

Yes, the same driver loading procedures apply to Windows 11. In fact, Windows 11 has better native support for modern NVMe drives, but the Intel RST issue persists on many Acer devices. You must still load the IRST driver during the initial setup phase if the drive remains undetected.

What if I cannot find the Intel RST driver on Acer’s website?

If the manufacturer site is unclear, download the driver directly from Intel’s official support portal. Search for "Intel Rapid Storage Technology Driver" and select the chipset corresponding to your processor. Extract the zip file to find the 64-bit driver folder, which contains the necessary files for the installer.

Is it safe to disable VMD Controller in BIOS?

Disabling the VMD (Volume Management Device) controller effectively switches the storage interface to a mode that Windows can understand natively. This is safe for installation purposes. However, if you plan to use Intel Optane memory later, you may need to re-enable it and configure it through the Intel management engine interface after installation.
