Size of standard persisent disk problem

In Google cloud console, under VM instances market place I chose NVIDIA Quadro Virtual Workstation - Windows Server 2019 as my compute engine and in it I chose standard persisent disk to be 200gb and created virtual machine. But when I open the VM the disk size is 50gb only. Please help

Hi Maraleee

Please use Windows Disk Management console to extend the partition size to 200GB.
