And now… the 4 magic USB .efi solutions are working again. o_O

@sudburr ok so I’m a bit confused. It appears that you can network efi boot these devices. Is your goal to legacy boot these devices?
I can understand why the usb booting would work over network booting the same iPXE kernel if the netboot code is fault in the yoga’s firmware. We have seen the hand-off between firmware and iPXE fail on some of these lenovos in the past.

Just trying to find the path of least resistance given our environment. The 4 USB .efi solutions are now working again. Murphy has passed out in the corner.

@george1421 Like I mentioned above, the Lenovo ThinkPad 13 works perfectly with the same BIOS setup. No need for the USB solution that the Yoga 260 requires for UEFI/Legacy dual booting. I fully believe the problem is entirely with the firmware on the Yoga.
Both work better now than they did 4 months ago with the BIOS version available then.
