First of all,
:wave: Welcome to TechSpot :wave:
If you would edit your first post and change the subject to something a little bit more helpful you might get some more responses. With a general statement like that people tend to look over it because it isn't specific.
As far as the boot keys go, I am also unsure of exactly what you mean. Any extra information is helpful and can never hurt.
Thank you, and I hope you enjoy your time spent here.
