If you tell me your computer model and CPU generation (e.g. 10th Gen Intel, 11th, 12th etc.), I can tailor the instructions specifically for you.\n\n---\n\n## Why the IRST/VMD Driver Needed\n\n- On newer Intel platforms (11th Gen and later), the **Volume Management Device (VMD)** technology is used. Windows install media does **not** always include the appropriate driver, so your NVMe SSD or SATA drive may not be visible until you supply that driver manually during setup. ([dell.com](https://www.dell.com/support/kbdoc/en-us/000188116/intel-11th-generation-processors-no-drives-can-be-found-during-windows-10-installation?msockid=39ac3afdad3861263ec02c5eacf06058&utm_source=openai))\n- If your BIOS is set to RAID or IRST mode, or VMD is enabled, the stock installer often can\u2019t see storage devices without the right driver. ([dell.com](https://www.dell.com/support/kbdoc/en-us/000188116/intel-11th-generation-processors-no-drives-can-be-found-during-windows-10-installation?msockid=39ac3afdad3861263ec02c5eacf06058&utm_source=openai))\n\n---\n\n## Step-by-Step \u2013 How to Correctly Load the IRST/VMD Driver\n\nHere\u2019s a general outline. Your model or BIOS layout might differ somewhat, but these are the core steps.\n\n1. **Download the proper IRST driver:**\n   - From Intel\u2019s website: latest \u201cIntel Rapid Storage Technology Driver Installation Software with Intel Optane Memory\u201d for your CPU generation. ([intel.com](https://www.intel.com/content/www/us/en/download/19512/intel-rapid-storage-technology-driver-installation-software-with-intel-optane-memory-10th-and-11th-gen-platforms.html?utm_source=openai))\n   - Alternatively, from your system/motherboard manufacturer (Dell / HP / Acer / MSI, etc.), using your model/serial number. ([community.acer.com](https://community.acer.com/en/discussion/732968/irst-driver-problems-with-reinstallation-windows-11-on-a-predator-ph315-54?utm_source=openai))\n\n2. **Extract the driver files:**\n   - If Intel gives an `.exe`, run it with the \u201cextract drivers\u201d option (e.g. `SetupRST.exe -extractdrivers <folder>`) to get the raw driver files (`.inf`, `.sys`, `.cat`, etc.). ([intel.com](https://www.intel.com/content/www/us/en/support/articles/000057787/memory-and-storage/intel-optane-memory.html?utm_source=openai))\n   - If the manufacturer gives a `.zip` or `.exe`, extract it so you can access the driver folder. ([community.acer.com](https://community.acer.com/en/discussion/729723/acer-nitro-an515-57-windows-11-clean-install?utm_source=openai))\n\n3. **Prepare USB media:**\n   - Use one USB stick for the Windows 11 install media.\n   - Copy the extracted driver folder (or entire folder with the RST files) onto the same USB drive under a separate folder (e.g. `\\Drivers\\RST\\`), or use another USB drive. ([dell.com](https://www.dell.com/support/kbdoc/en-us/000188116/intel-11th-generation-processors-no-drives-can-be-found-during-windows-10-installation?msockid=39ac3afdad3861263ec02c5eacf06058&utm_source=openai))\n\n4. **Check/Change BIOS settings before install:**\n   - Ensure UEFI boot mode is set (not Legacy). IRST/VMD setups often require UEFI. ([intel.com](https://www.intel.com/content/www/us/en/support/articles/000057787/memory-and-storage/intel-optane-memory.html?utm_source=openai))\n   - Enable VMD controller if your system supports it, and set the storage SATA/NVMe ports you\u2019ll use under that controller. ([intel.com](https://www.intel.com/content/www/us/en/support/articles/000057787/memory-and-storage/intel-optane-memory.html?utm_source=openai))\n   - If it\u2019s currently AHCI mode, you might need to switch to RAID/IRST mode\u2014this depends on your mainboard. If VMD is enabled then AHCI may not work as expected. ([community.acer.com](https://community.acer.com/en/discussion/729723/acer-nitro-an515-57-windows-11-clean-install?utm_source=openai))\n\n5. **Begin Windows installation:**\n   - Boot from your USB Windows 11 installer.\n   - Proceed until you reach the \u201cWhere do you want to install Windows?\u201d screen.\n   - If no drives appear, click **Load driver**. ([dell.com](https://www.dell.com/support/kbdoc/en-us/000188116/intel-11th-generation-processors-no-drives-can-be-found-during-windows-10-installation?msockid=39ac3afdad3861263ec02c5eacf06058&utm_source=openai))\n\n6. **Load the IRST driver:**\n   - Click **Browse**, navigate to the driver folder you prepared.\n   - Find the appropriate folder: on VMD systems look under something like `Drivers\\VMD\\f6vmdflpy-x64` and select the `.inf` file such as `iaStorVD.inf`. On older AHCI/RAID setups it's often `iaStorAC.inf` or similar. ([intel.com](https://www.intel.com/content/www/us/en/support/articles/000057787/memory-and-storage/intel-optane-memory.html?utm_source=openai))\n   - Choose this driver and proceed. The installer should now detect your storage drive. ([dell.com](https://www.dell.com/support/kbdoc/en-us/000188116/intel-11th-generation-processors-no-drives-can-be-found-during-windows-10-installation?msockid=39ac3afdad3861263ec02c5eacf06058&utm_source=openai))\n\n7. **Continue installation:** \n   - With the drive visible, format or delete partitions as needed, then install Windows.\n   - After Windows is installed, install the full IRST driver software (like `SetupRST.exe`) so you get the management tools and full support. ([intel.com](https://www.intel.com/content/www/us/en/support/articles/000057787/memory-and-storage/intel-optane-memory.html?utm_source=openai))\n\n---\n\n## Common Pitfalls & Troubleshooting\n\n| Problem | What\u2019s going wrong | How to fix |\n|---|---|---|\n| Driver not recognized when using \u201cLoad driver\u201d | Might have wrong driver version (VMD vs non-VMD), wrong CPU generation driver, or missing correct `.inf` file. Driver signature issue could also exist. ([community.acer.com](https://community.acer.com/en/discussion/729723/acer-nitro-an515-57-windows-11-clean-install?utm_source=openai)) | Download the exact IRST driver that matches your CPU platform, use the correct subfolder, verify `.inf` presence. |\n| \u201cNo signed device drivers were found\u201d error | Driver might be unsigned, or BIOS secure boot interfering. Or wrong folder. ([learn.microsoft.com](https://learn.microsoft.com/en-us/answers/questions/b7f7e7a5-5757-4a1b-a103-1519c1eaca4b/windows-11-home-clean-installation-from-pen-drive?forum=windows-all&utm_source=openai)) | Ensure secure boot is off temporarily, use officially signed drivers, ensure you pick correct folder. |\n| After installing driver, installer crashes or reboots | Conflicts in BIOS (wrong controller mode), using outdated driver, or BIOS version too old. ([community.acer.com](https://community.acer.com/en/discussion/729723/acer-nitro-an515-57-windows-11-clean-install?utm_source=openai)) | Update BIOS to the latest version; check storage controller/SATA/NVMe/VMD settings; maybe disable VMD temporarily and use AHCI if you can. |\n| Drive visible only in BIOS but not during install | Missing driver, or \u201cLoad driver\u201d process wrong. ([techcommunity.microsoft.com](https://techcommunity.microsoft.com/discussions/windows11/hp-15s-fq2811nc-72h94ea-win-11-install---ssd-not-found-missing-irst-driver/4444913/?utm_source=openai)) | Use \u201cLoad driver\u201d, find correct path, ensure VMD is enabled in BIOS. |\n\n---\n\nIf you tell me your system model (for example, HP 15s-fq*, Dell XPS, Acer Predator PH315-54, etc.) and which generation Intel CPU (10th, 11th, 12th, etc.), I can pull up exact driver links and BIOS settings for your machine to make things smoother. Do you want me to do that?"
