**Step 2:** Navigate to **Compute** and then click on **Instances**.
**Step 3:** Choose the instance for which you want to attach the volume, click the **drop-down**, and choose **Attach Volume.**
**Step 4:** Select the **Volume** and click **Submit**.
**Note:** The volume should already be created and not attached to any instance.
With the above steps, the volume has been attached but not mounted. We must follow the steps below to mount the attached volume to our Windows machine.
**Step 1:** Select your instance and click on **Instance Name.**
**Step 2:** Click on the **Console** tab.
**Step 3:** On the remote desktop, right-click the **Start** button and click **Disk Management** from the list.
A dialogue box appears, showing all the disks available on the computer. The unallocated disk is marked with a red sign, which we'll allocate in the further steps.
**Step 4:** The attached disk will be available offline. To make it online, on the unallocated disk, right-click and select **Online**.
**Step 5:** You'll likely need to initialize a disk when creating a brand-new storage device before using it. To do so, right-click again on the unallocated disk and select **Initialize Disk**.
**Step 6:** A setup dialogue box appears; click **Next** to continue.
**Step 7:** You’ll be asked for the partition style; select **MBR (Master Boot Record)** and click **OK**. If your disk space is over 2TB, you may use a **GPT (GUID Partition Table)**.
The setup wizard shows the minimum and maximum disk space availability in MBs and allows the user to modify the volume size as per the requirements.
**Step 8:** Select the volume size and click **Next**.
**Step 9**: Choose the preferred drive letter from the drop-down menu and click **Next**.
**Step 10**: Click **Finish**.
The volume has been successfully allocated, which you can see in the console windows of **This PC**.
