Boot scan not working in safe mode

I think my computer got a bug or two. I ran a boot scan and it found some errors and some bugs and I sent them to the vault but I wanted to run it in safe mode. I can schedule it and restart the computer but it does not run. It just loads windows.
I am running 7.

That’s on purpose - the safe mode prevents any print-outs from an application like the boot-time scan; the program would be invisible and you couldn’t interact with it. That’s why the boot-time scan doesn’t start in safe mode.
