How to enter BIOS or boot menu of Lenovo IdeaPad Yoga 11?

On Lenovo ideapads, If hotkey is enabled use fn+f2 for bios setup and fn+f12 for boot menu.

If hotkey is disabled then f2 and f12. Press the key(s) and power on while still pressing it.

If you need to boot from cd then insert CD before shutdown and power on with f12. The CD option will appear if CD is inserted. Hotkeys are disabled or enabled in bios setup.

For Lenovo Ideapad or Yoga machines: power it down and then start it using the Novo button. This is the tiny button to the left of the power button and you should then see options which allow you to choose the Boot Device, enter BIOS etc.

If your Yoga does not have a Novo key (applies to some early models) then you should be able to get into these settings by pressing the F12 key repeatedly after booting.

The best solution was a hammer. R.I.P. Yoga 11.
