I upgraded to Catalina, updated to the latest version of Parallels Desktop, reinstalled Parallels Tools on the VM, yet still the following problem persists:
When firing up any of my Windows 2016 VMs, rather than loading the OS, a Boot Manager screen is displayed. Windows 2016 is the only option on the boot manager. Selecting it successfully loads the OS.
Uninstalling and reinstalling Parallels Desktop didn't solve the problem.
