Hello,
My PC displays "efi pxe network (f8-75-a4-45-eb-5b) boot failed" and cannot start after a BIOS update recommended by Lenovo Vantage.

The boot option menu only shows EFI PXE network (f8-75-a4-45-eb-5b) in its list.

This is a Lenovo Legion Y540.

Thank you in advance for your responses.

If it's there:

If you don't want to repair it, you can reset it: how to factory reset a Lenovo PC

Otherwise, to try to recover your Windows 10 installation:

  • Boot from it by modifying the boot sequence and indicating the USB drive or DVD: How to boot the computer from a USB drive
  • You will arrive at the Windows installation program.
  • Go to repair your computer (menu at the bottom left on the main page)
  • Advanced troubleshooting options
  • Command prompt
  • type diskpart and press enter

Give the result of the following commands: 

list disk
sel disk 0
list partition
list volume
exit


Take a photo of the result and provide the result as a screenshot.

And give the result of the command: 
bcdedit /v


Take a photo of the result and provide the result as a screenshot.

Thank you for your response!
The PC finally restarted after disabling secure boot in the BIOS and setting boot mode to legacy support and boot priority to legacy first as shown below.


Attached is the photo of the commands you asked me for.
