# Windows is Unable to Detect a Virtual Disk Drive

### Virtual Disk Drive not detected in Windows

In most cases this is because the disk drive **Interface Type** is set to **virtIO-SCSI** (which is the default value) on any virtual machine that is being created. If that is the case, you will need to load the **virtIO drivers** during the Windows installation process. Windows does not natively recognize virtIO interfaces, so it cannot see the virtual disk.

Open Source virtIO drivers can be downloaded from [here](https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/README.md) courtesy of Fedora Linux.

If Redhat virtIO drivers are required due to signed driver needs within Windows, a Redhat account will need to be made on their website and the drivers downloaded directly from them.

### Installing virtIO Drivers during Windows Install

During a Windows installation, users can use the console interface tools to change the CD-ROM image to the newly downloaded virtIO drivers iso. Information on using the console interface tools can be found in the inline help within the category titled **VDI** under the section **Using the Console**.

Alternatively, you can choose to change the virtual disk drive **Interface type** to **SATA** and Windows will find the virtual disk and continue with the installation. !! info "This will come with a performance impact due to SATA drivers being software emulated."
