The previous article explained how to resize a disk on a Linux VM on proxmox. This article will explain how to resize a disk on a Windows VM in proxmox.
How to resize disk on Windows VM in proxmox?
In this article, I use Windows 10 on a VM on proxmox. As before, before resizing the disk, turn off the VM. Before turning off the VM, I took a screenshot on the VM’s HDD:
Turn off the Windows VM then I increase the HDD of the VM by 20 GB which is located in VM > Hardware > Hard Disk > Resize disk
After that, turn on the VM and if you check the size of the HDD, the size is still the same. Therefore, we must configure the hard disk partition on the VM. Type the command diskmgmt.msc on Windows, then Windows will open the default partition application on windows, as shown below:
As seen in the image above, the additional HDD we just inserted into the VM is still not configured. Then we have to do the configuration so that the new HDD can be used. Right-click on the HDD Drive C partition, as in the image below and my plan is to merge Drive C and the new HDD:
Then click on the Extend Volume section, then there will be a pop-up like in the image below:
Click the Next button, then there will be a display like in the image below:
As seen in the picture above, the new HDD has been selected, click the Next button, then there will be a display as below:
Press the Finish button. Then the HDD partition on the VM will be like in the image below:
After that, look at the size of the HDD, then the HDD size should increase by 20 GB.
Although in this article I use Windows 10, we can use these steps on any Windows OS. In addition, in this article, I use the default Windows partition application to merge partitions, but you can also use other Windows partition applications available on the internet such as the AOMEI partition or minitool partition disk, etc.
