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.

    • type diskpart and press enter

    Give the result of the following commands:

    list volume
    exit


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

      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.
