Can't restore because it isn't showing me a Restore Point

I backed up my system using Comodo Backup to a network drive.

I rebuilt my system because of an issue. But on the rebuild, I virtualized it in VirtualBox so that I’d be able to do snapshots and images more easily.

Now I’m trying to restore the backup. I installed CB, and can successfully Verify the previous backup. But when I go to Restore it, it only presents “Disk0()” as the available files to restore (which I check) and nothing for the Restore Point. When I click Next, it insists that I select a(n unselectable) Restore Point.

How can I recover my system?

Thank you,
Rob
