Yoga 3 Pro 1370 -- unable to boot to usb, not the usual problem ...

My buddy aquired a Yoga 3 Pro 1370 HE80 at the County Sheriff's auction. The LAW tries to  wipe the laptops they sell -- in this case I think they damaged the UEFI. 

 

Here is what the bios says .  Note that there is no windows boot manager listed under EFI ...

Yes I tried changing to "Legacy" -- and that results in an endless loop of the Lenovo logo flashing. 

 

I followed the lenovo instruction for creating a proper UEFI boot usb that I found here https://support.lenovo.com/pe/en/solutions/ht076615

 

I also created one via Microsoft media tool. 

 

Here is what happens. IMG_20180519_223235.jpg

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Next , I get this ... nothing bootable is listed (despite proper UEFI USB drives being inserted in the machine.

Anyone know of a way to fix the firmware? Is that even the issue? 

 

Thanks in advance.

Are you sure there is still a HDD in the laptop?     They may have wiped it by simply removing the HDD, because should still be given the option to set the HDD as a boot device even if as EFI

Ok -- this was my mistake. Evidently it is possible to use the Microsoft Media Creation tool to create a USB stick that has MBR instead of a GUID partition scheme. So I ditched the Kingston USB 3.0 drives and used Rufus to create a new USB 2.0 (generic) stick with the UEFI and GUID partition scheme option (and a windows 10 iso). Don't know if the USB 3 or 2 thing factored in on this ... but now Cortana is talking to me. Talking too much.
