How to access bios on Lenovo ideapad 100s 11IBY cause i tried f2 f12 and delete?

The keys used to get into bios are Esc. Del. F2, F11, F12, now if you don't press the keys at the right time you miss it… Now when your computer is booting up the second you press the power button LOOK at the bottom LEFT corner of the monitor and for a couple of seconds it should tell you what keys to press to get in the Biso or boot up device

I DID and there were no keys show up

lenovo says F2 is the key… So as soon you press the power on button start tapping the F2 key…

Go to your system settings>Update & Recovery>Recovery then click Restart now under the Advanced startup section. The device will reboot to the Windows Advanced startup screen, go to Trouble shoot>Advanced Options> UEFI Firmware Settings. This will load up the BIOS settings screen.
Hope this helps.

Fn+f2
