How to reattach an OS Disk after detaching from a VM?

Hi @Jugert Mucoimaj ,

in the Azure Portal navigate to the unattached disk (Search for Disks and navigate/open the unattached disk in the list).

In the top menu of the disk detail blade click on + Create VM and follow the wizard.

Hello Jugert Mucoimaj

To do that you need to follow these steps on the new VM:

1. Go to the Azure portal and select Create a resource > Virtual Machine
2. In the Disks section of the VM creation, select "Use an existing disk" for the OS disk
3. Browse to select your OS disk from the list of available disks
4. Complete the rest of the VM configuration

Hi Jugert Mucoimaj

As shown in your picture, after deleting the VM, go to the Azure portal -> Disks.

Select the disk that has been retained and ensure it is not attached to any VM.

Next, Go to Azure portal -> Virtual Machines -> Click create. In the Disks tab of the VM creation wizard, select Use an existing disk, then choose the retained OS disk. Proceed to create the VM with the necessary details.
