Very interesting; very helpful. Thank you.
I installed BootitNG some time ago, forgot about it, and finally uninstalled it when I saw the trial time was about up. It left me a little something - a scan by NOD32 now tells me that it can't any longer read the boot sector on any of my 4 hard drives. It's clearly something tiny and technical because the system continues to work well.
Having read your posts here, I'm going back for a proper look at NG.
