Make sure you created the USB correctly and check your BIOS settings (UEFI enabled, secure boot disabled, etc.).

I did. But when Secure Boot marked Disabled, Secure Boot Status still said Enabled and can not be changed

No idea without seeing some screens of your BIOS and an idea of what exactly you did to prepare your USB. If you're saying the USB works on another computer, then it must be a BIOS problem or a problem with the USB ports. For example, my u430 BIOS will not recognize a certain USB3 stick I have unless it is plugged in via a powered USB2 hub.

After choosing USB as boot drive BIOS immediately pop-up a notice that it block USB from booting.
It means that it can not even boot into clover screen to select further.
BTW I used your guide to make USB boot.
Here are the screen shot of my computer

You need to disable secure boot. Make sure you change the setting and save, then verify. Try enabling legacy boot, even though you won't be using it.

Already tried all of those. Maybe I need a modified BIOS version

Until you get Secure Boot status to show disabled, there is no chance.

I've noticed that even my u430 is buggy with regard to the secure boot setting. You'll need to wiggle it a bit, until it reads as it should and allows non-secure USB boot.

Try setting defaults..., then enable legacy (legacy boot implies secure boot disabled).

Tried everything. Turn on legacy boot does turn off secure boot but only for legacy boot only. As soon as USB boot in UEFI mode it turn on secure boot.

I'm on version 2,01. lenovo really locked down EFI, it prevents you from booting into or even changing secureboot status if Windows boot manager is present and was installed with secureboot enabled. Only thing that works for me is renaming \efi\microsoft\boot\bootmgfw.efi to \efi\microsoft\boot\bootmgfw.<any other extensions>.
If you do not have windows preinstalled, then I suggest you erase your EFI partition, reset UEFI, disable secureboot and boot from clover (as RehabMan) said.

On a side note, has anyone managed to get HDMI audio working with FakePCIID_Intel_HDMI_Audio.kext?
