Hello friends. I need to know how we can access the boot menu on lenovo laptops? What function is being used for boot from the cd, dvd or flash in such laptops? And is this function the same on all models or they are different?
We have one key to boot directly from harddrives or flash disks or dvd/cd rom based on what prioritize was already set from the bios and also there is one function that leads us to a menu which we can choos how do we want our system to be booted, so I'll be glad if you tell me the both functions, and I'll kindly appreciate your great help! Have a good day.

Try pressing F11 when loading.
