uefi Boot Manager - Thinkpad Yoga - Boot Menu

[majac89]

Hi, I'm trying to set up a dual boot system on my new Thinkpad Yoga and I have a couple of questions related to its uefi Boot Manager.

On power up I can press F12 in order to pop up a Boot Menu in which I'm able to select among the entries that I have set using the uefi shell command bcfg. Now I would like to know if it is possible to instruct the uefi Boot Manager in order to display the Boot Menu without pressing the F12 key.

When I use bcfg boot dump within a uefi shell in order to see the possible entries of the Boot Manager I can see options like these:

Code:

Option: 10. Variable: Boot0010
Desc - Setup
DevPath - FvFile(86488440-41BB-42C7-93AC-450FBF7766BF)
Optional- N
Option: 11. Variable: Boot0011
Desc - Boot Menu
DevPath - FvFile(126A762D-5758-4FCA-8531-201A7F57F850)
Optional- N

however even if I set the Boot Menu option to be the first:

Code:

bcfg boot mv 11 1

the Boot Menu does not appear without pressing F12. Any ideas?

(I want to do so mainly because pressing F12 cause an irritating mobo beep which I cannot disable and because I'm curious about the possibility of setting up a dual boot system without installing an additional boot loader)
