UEFI EFI Shell: Cannot read from file - 800000000000001F

@PeterCxy - This method doesn’t appear to work for Bios version 0.22
I get the following after the "Press Esc in x seconds to skip startup.nsh, any other key to continue.
I let the timer countdown
Shell: Cannot read from file - 800000000000001F
Do you have any ideas/suggestions as to why?
Thanks.
