Solving "No Drives Found" During Windows Installation: A Guide to vmd_dch_intel_f_v19.5.1.1040_30787 If you are trying to install Windows 10 or 11 on a new Intel 11th, 12th, 13th, or 14th Gen laptop—particularly ASUS models—you may have encountered a frustrating issue: the Windows installer cannot find any hard drives or SSDs . This is not a hardware failure. Instead, it is a driver necessity driven by Intel Volume Management Device (VMD) technology, which requires the Intel Rapid Storage Technology (IRST) driver to be loaded during setup. The vmd_dch_intel_f_v19.5.1.1040_30787 package is specifically designed to solve this problem. What is vmd_dch_intel_f_v19.5.1.1040_30787? This file name refers to a driver package for Windows (often used by ASUS as VMD_DCH_Intel_F_V19.5.1.1040_30787 ) that enables the Intel Rapid Storage Technology (IRST) controller. VMD (Volume Management Device): A feature in modern Intel CPUs that allows NVMe drives to be directly managed by the processor for better power management and hot-plugging. DCH (Declarative Componentized Hardware): A new type of Windows driver designed for modular installation. v19.5.1.1040: The specific version of the IRST/VMD driver. 30787: Often part of the ASUS internal build or file ID string. Without this driver, the Windows installation media cannot communicate with the Intel VMD controller, resulting in an empty storage list. Why Do I Need This Driver? When VMD is enabled in the BIOS, the SSD is hidden from the standard Windows installer. This is designed for RAID setups or to utilize faster, more efficient direct-to-CPU storage communication. However, it requires a driver that Windows doesn't include in its base installation media. Steps to Install the Driver (vmd_dch_intel_f_v19.5.1.1040_30787) Follow these steps to extract and load the driver during Windows setup. 1. Download and Extract On a working computer, visit the official ASUS support page for your specific laptop model. Download the Intel Rapid Storage Technology (IRST) driver (v19.5.1.1040_30787) from the Chipset category. Double-click the downloaded executable file (e.g., VMD_DCH_Intel_F_V19.5.1.1040_30787.exe ). Choose [Extract] in the installation wizard and select your USB flash drive (which should be your Windows installation media) as the destination folder. Ensure the files (specifically the .inf, .sys, and .cat files) are extracted to a folder on your USB drive. 2. Load Driver During Windows Installation Connect the USB drive to your new computer and boot from it. When you reach the "Where do you want to install Windows?" screen and no drives appear, click [Load driver] . Click [Browse] and navigate to the folder where you extracted the driver files on your USB drive. Select the folder (often named RST ), and click OK. Select [Intel RST VMD Controller] and click Next. Once the driver installs, your storage drives will appear, and you can continue with the installation. Alternative Solution: Disabling VMD in BIOS If you cannot load the driver, you can disable VMD in the BIOS, although this may reduce the power efficiency benefits of your NVMe drive. Enter BIOS (usually by pressing F2 or Delete at startup). Go to Advanced Mode (F7). Navigate to Advanced -> VMD setup menu . Set Enable VMD controller to [Disabled] . Save and Exit (F10) and restart the Windows installation.

The identifier "vmd_dch_intel_f_v19.5.1.1040_30787" refers to the Intel Rapid Storage Technology (IRST) driver. This specific version is primarily used during a Windows installation to allow the setup process to "see" NVMe SSDs on modern Intel platforms (11th Gen and newer) . If you are a developer looking to "develop a feature" or integrate this driver into a deployment pipeline, the most common use case is Driver Injection into a Windows Image (.WIM) or an automated installation script. 🛠️ Implementation: Injecting the Driver into Windows Media To automate the deployment of this driver so users don't have to manually "Load Driver" during installation, you can use the Deployment Image Servicing and Management (DISM) tool. 1. Extract the Driver The .exe or .zip file must be extracted to get the raw .inf , .sys , and .cat files. Run the installer and select Extract rather than Install . Target a folder, e.g., C:\Drivers\Intel_VMD . 2. Inject via CLI (PowerShell/CMD) Use these commands to inject the VMD driver into a mounted Windows image: powershell # 1. Mount the Windows Image (boot.wim or install.wim) dism /Mount-Wim /WimFile:C:\ISO_Files\sources\boot.wim /Index:2 /MountDir:C:\Mount # 2. Add the VMD Driver dism /Image:C:\Mount /Add-Driver /Driver:C:\Drivers\Intel_VMD /Recurse # 3. Unmount and Save Changes dism /Unmount-Wim /MountDir:C:\Mount /Commit Use code with caution. Copied to clipboard 💻 Integration for Automated Setups If you are developing a custom OS deployment tool (like a WinPE-based installer), you should focus on the following: 📂 File Structure Requirements For the driver to be recognized, your source folder must contain: iaStorVD.inf (The setup information) iaStorVD.sys (The actual driver binary) iaStorVD.cat (The security catalog) ⚙️ BIOS/UEFI Considerations VMD Enabled: The driver is mandatory for the OS to detect the drive . VMD Disabled: The OS uses standard NVMe/SATA protocols, and this specific driver package may not be required . 💡 Troubleshooting Common Issues "No signed drivers were found": Ensure you are using the F6 or Floppy version of the driver package, not the standard Windows installer. Drive still hidden: Verify the VMD Controller is enabled in the BIOS under "Advanced" or "Storage" settings . Version Mismatch: Version 19.5.1.1040 is optimized for 12th/13th Gen Intel CPUs. Older or significantly newer hardware may require a different branch (e.g., v17.x or v20.x) . If you'd like, I can provide more specific help if you tell me: Are you building a custom ISO or an automated deployment (SCCM/MDT)? What is the target hardware (laptop model or motherboard)? Are you trying to write a script to automate this across multiple machines?

Overview of Intel VMD DCH Driver Intel's Volume Management Device (VMD) is a feature that allows for the management of NVMe SSDs directly connected to the PCIe bus, providing a level of abstraction and management capabilities similar to what is offered by AHCI for traditional SATA drives. The DCH refers to the driver package format that is compatible with the DCH (Device Control Model) specification by Microsoft, which standardizes the way drivers are packaged and installed on Windows systems.
