    Windows 10 guest OS with legacy bios. Updated to Parallels ver 18 and now won't startup
    Windows boot manager flashes on the screen briefly stuck in a loop but doesn't boot. Have looked at the KB's and tried the suggested vm.bios.efi=0 boot flag but this down't work either. Any suggestions please?
