Error: UEFI setting must be the same for the instance and the boot disk. While editing the VM Instance in GCP

Question

Basically I want to take a backup of a VM machine in GCP and came to know about snapshot. So I am trying to use snapshot feature of GCP I created a snapshot of a machine called angular(this machine contain data of angular and node) here is the image of the snapshot:

Now I want to use this snapshot to restored the data and I don't want to create a new instance, I get one way in which first you have to remove the boot disk of the instance in which you to restore the snapshot data and then create a new disk using that snapshot and then use that disk. I tried this technique but I am getting this error:

Error:

UEFI setting must be the same for the instance and the boot disk.

image of disk that I created using snapshot:

Image of VM instance in which I want to use the new disk (created from the snapshot):

What am I doing wrong?

I think your instance might not be compatible with UEFI. On Google Cloud there are some images that are UEFI compatible and others that are not. You can check if your instance is UEFI compatible with the following command (put the correct zone):

$ gcloud compute instances describe your-instance --zone=europe-west4-b | grep type:

If the instance is compatible, you will see type: UEFI_COMPATIBLE as a result. If it is not compatible, you will not see it. I think that currently it is not possible to edit UEFI compatibility on an instance. However, you can check what images are UEFI compatible. Here are a couple of examples:

Compatible:

$ gcloud compute images describe-from-family rhel-7 --project=rhel-cloud  | grep type:
- type: UEFI_COMPATIBLE

$ gcloud compute images describe-from-family rhel-8 --project=rhel-cloud  | grep type:
- type: UEFI_COMPATIBLE

Not Compatible:

$ gcloud compute images describe-from-family debian-9 --project=debian-cloud  | grep type:
- type: VIRTIO_SCSI_MULTIQUEUE
