I launched a g5.2xlarge (Windows) instance type about a week ago. I've configured it exactly how I need and used the console to create an image of the server. The server contains only a single 150 GB EBS root volume. The image is created successfully but when I go to launch a second g5.2xlarge instance using this AMI, it shows the following under storage. I'm not sure where the second 450 GB volume is coming from or why I can't remove it.

When the server is launched, I can see the 150 GB volume (but not the 450 GB one) in Windows but none of the data (files, configs, drivers, etc.) from the original server are there. It just looks like a bare Windows install. Did the data copied to that second invisible volume or something? Basically, all I want is an instance that's identical to the one I've already configured. I've done this successfully in the past but usually with Linux and with different instance types.
Thanks.
