If you choose to create a new disk, specify the size and location for the new virtual hard disk file. If you choose to use an existing disk, browse for the file in the appropriate location.
7. Customize any additional settings, such as the disk format (VHD or VHDX) and storage type (fixed or dynamically expanding), according to your requirements.
8. Click “Apply” and then “OK” to save the changes.
9. Start the virtual machine if it is not already running.

Once the virtual machine has started, the newly added virtual hard disk will be available. You can then initialize and format it within the virtual machine’s operating system, just like any other disk.

Adding a virtual hard disk using Hyper-V Manager provides a simple and intuitive way to expand your virtual machine’s storage. However, it is important to ensure that you have enough physical storage space on your server or storage device to accommodate the new virtual hard disk.

In the next method, we will explore how to use PowerShell commands to add a virtual hard disk to a Hyper-V virtual machine.

Method 2: Using PowerShell to Add Virtual Hard Disk

If you prefer to use PowerShell commands for managing your Hyper-V environment, you can add a virtual hard disk to a virtual machine using PowerShell. This method provides more flexibility and allows for automation if you need to add multiple virtual hard disks or perform the task on multiple virtual machines. Here’s how you can do it:

1. Open PowerShell with administrative privileges.
2. Use the “Add-VMHardDiskDrive” cmdlet to add a new virtual hard disk to the desired virtual machine. Specify the virtual machine name using the “-VMName” parameter and provide the path to the virtual hard disk file using the “-Path” parameter.
3. If you want to create a new virtual hard disk file, you can use the “New-VHD” cmdlet to create a VHD or VHDX file with the desired size and specifications. Then, provide the path to this newly created file in the “-Path” parameter of the “Add-VMHardDiskDrive” cmdlet.
4. Customize any additional settings, such as the disk format (VHD or VHDX) and storage type (fixed or dynamically expanding), according to your requirements using the appropriate parameters.
5. Run the command and verify that the virtual hard disk has been added to the virtual machine.
6. Start the virtual machine if it is not already running.

Using PowerShell to add a virtual hard disk provides a flexible and efficient way to manage storage in your Hyper-V environment. You can easily create and add multiple virtual hard disks with specific configurations, and automate the process for easier management and scalability.

In the next method, we will explore how to add a physical hard disk directly to a virtual machine to further expand its storage capacity.

Method 3: Adding Physical Hard Disk to Virtual Machine

If you have available physical hard disks that you want to utilize directly within your virtual machine, you can add them to the virtual machine in Hyper-V. This method allows you to leverage the existing storage devices and maximize the storage capacity of your virtual machines. Here’s how you can add a physical hard disk to a virtual machine:

1. Ensure that the physical hard disk you want to add is connected to the server hosting the Hyper-V virtual machine. It can be connected via SATA, SAS, or other supported connections.
