Hi @Myo Thiha
Thank you for reaching out to the Microsoft Q&A platform.
I just tested this in my 2 different subscriptions, one pay as you go model, and another is a visual studio subscription with azure credits, and I can see the create VM button on the disk that I have created out of a snapshot of my other VM's OS disk.
I don't think this is a limitation on the subscription type. What type of subscription are you using?
The 3 important steps involved in creating a VM from a snapshot are
- Create a snapshot of the disk.
- Create a managed disk out of the snapshot.
- Create an azure VM out of that managed disk created. After you have the disk that you want to use, you can create the VM in the portal:
- In the search box, enter disks and then select Disks to display the list of available disks.
- Select the disk that you have created and would like to use. The Disk page for that disk opens.
- In the Essentials section, ensure that Disk state is listed as Unattached. If it isn't, you might need to either detach the disk from the VM or delete the VM to free up the disk.
- In the menu at the top of the page, select Create VM.
