How do I open the boot menu?

12.04 boot grub2

This from Lenovo:

While the "To interrupt normal startup, press Enter" message is displayed at the lower-left area of the screen, press the F1 key. The BIOS Setup Utility menu will be displayed. If a password prompt appears, type the correct password.

    I want to uninstall 12.04 and install Ubuntu 13.04 instead.

    When I was installing Ubuntu 12.04 from Windows 7 opened the boot menu F12.

    I have read that on Ubuntu to enter the boot menu I have to press F2 or Fn-F2. I have tried both ways but it still doesn't open the boot menu.

    So, how can I open the boot menu on Ubuntu 12.04?

    Note: I'm using a Lenovo ThinkPad X120e.

      The BIOS exists outside of and before any OS, so there is no "on Ubuntu" part to entering the BIOS.

      For me all you have to do is the moment you turn on the machine keep pressing shift to you come to a menu that says *ubuntu advanced options for ubuntu you want the advanced option then click recovery mode it will then all you have to do is click down to root and there you go
