N540X-16Z4G8Q2C USB Boot Failure

[PK99]

Can someone assist me.

I have created a bootable USB with ncs540-usb_boot-7.x.x.zip. I moved the zip file to the USB and extracted the ZIP file and moved 

boot & EFI folders to the root of the USB 

I insert to the router, power it on, break the boot by hitting ESC.  Enter to boot menu and select the USB and it keeps failing.

I have tried it on USB1, USB2, USB3 and all 3 have same failure.

Can anyone shed any light?

This model runs XR7, did you download the USB file for eXR NCS540 models or XR7 NCS540 models?

You need ncs540l-usb_boot-7.8.1.zip not ncs540-usb_boot-7.8.1.zip, the non-L image should not be in this list:
