What to do if advance start up options does not come up?

[ladybluedawg0224]

I can’t remember my windows password to log in to my Lenovo ThinkPad edge laptop and I read about this advance start up options that would reset my laptop to factory settings but I can not for the life of me get the advance start up options screen to come up? Please help

have you tried pressing F8 during boot?
