Yep. The special Rollback MBR (which includes its sub-Console code) was never installed. Most likely MBR modification was inhibited on the target system. This is usually due to some anti-V/anti-rootkit app running on the target system. You'll need to unInstall the broken Rollback, find the app that's inhibiting you and disable it until after you have made a successful installation. Edit: some systems even have a BiOS setting that sometimes disallows MBR modification... but that would be a last resort to check on.
