f8 doesn't start safemode in windows 7

I have been testing my p.c. to get it into safemode and did the msconfig and that worked to get into safemode. But for testing purposes say if I have to restart a computer, f8 opens the boot menu. Is there some way of getting safemode to work if you have to hard reboot a pc, say if everything locks up, from a virus or other problems? Any advice would be appreciated.

Thank you.

I found the answer, when I pressed F8 it would go to Boot device menu, I hit escape and pressed F8 (not tapped it) then the
Advanced Boot option menu would appear, and I could select safemode from the choice. I hope that my research and the video I found can help if anyone needs it.

Thank you.

You may need to hold down the FN (Function) Key before pressing the F8 key.
My Dell brings up the following when you just press the F8 Key:
