+To do this, run bootstrap followed by phase 1 (installation)—both are explained [here](./NS_Install.md).  
+Afterward, [restart](./Restart.md) the server. You can then proceed with phase 2, as explained in the same guide.

-Deleting the virtual machine is hardly ever necessary.  You shouldn't do it.  It is only a last resort.

-Therefore, if you are certain you need to delete it, follow the backup instructions above to backup everything including your database.  
+#### **Deleting the Virtual Machine**

-
-Now, you can follow the [guide](./GoogleCloud.md) to recreate a new machine.  Then, you can restore your backup on the new machine.

+If you are certain you need to delete it, follow the backup instructions above to secure all necessary files.  
+
+Only proceed with [deleting the machine](./DeleteVM.md) if you have no other recovery options and have ensured you have backed up everything.
