I got this error after I restored a time machine backup and had to rebuild my bootcamp from scratch.
Uninstalling and reinstalling vmware fusion didn’t help.
The solution was to delete the records of the old bootcamp setup and when i next opened vmware fusion and hit start on the bootcamp image, it rebuilt it and worked like a charm.
Delete the following folder with VMWare Fusion closed
\Library\Application Support\VMware Fusion\Virtual Machines\Boot Camp
Start VMWare Fusion and click start on the bootcamp image, it will rebuild and should start up fine.
