Detach Boot Disk from GCE VM

Question

I am trying to detach the Boot Disk from a GCE VM. As the VM is stopped so it should allow me to detach it but it\'s returning this error

UNSUPPORTED_OPERATI         


        

Answer 1

Detaching boot disks is now supported in Beta (docs). After shutting down instance, try: gcloud beta compute instances detach-disk INSTANCE_NAME --disk DISK_NAME

To re-attach a boot disk to the instance: gcloud beta compute instances attach-disk INSTANCE_NAME --disk DISK_NAME --boot
